Apart from addressing the root causes of a high electric bill, there are a few additional steps you can take to reduce your bill even further.
1. Invest in a Smart AC Controller or a Smart Thermostat
Heating and cooling costs make up a big chunk of your total electricity bill. Smart AC controllers can help you get AC costs under control through useful features such as geofencing, humidity and temperature triggers, usage tracking, etc.
2. Always Unplug Unused Appliances
Many modern – day energy appliances don’t shut down when given the command. Instead, they enter standby mode so they can power up quickly the next time you need to use them. The problem is that if you leave these devices plugged in, they will continue drawing energy. Over time, this energy usage adds up, leading to sky – high electric bills. So the next time you are wondering why your electric bill is so high, walk around your house and look for any unused devices still plugged in.
3. Turn Any Fans or Lights off When You Leave the Room
Many people believe that lights and fans don’t use much energy, so they don’t bother turning them off when they exit the room. However, if you routinely leave ceiling fans and lights on, you will have a high electricity bill. So make it a habit to check any lights and ceiling fans when you leave a room. You will notice a difference in your electricity bill soon enough.
4. Invest in an Electricity Usage Monitor
If you think an appliance consumes excess electricity, a watt meter or electricity usage monitor is your best friend. An electricity usage monitor helps you determine how much electricity an appliance uses. Plug the monitor into an outlet, and then plug your appliance into the monitor. Then, run the appliance for 24 hours. The monitor will tell you its electricity consumption for 24 hours. Multiply that figure by 365 to get an idea of your yearly cost. An electricity usage monitor can help you understand why your electricity bill is so high and where you need to reduce usage.
5. Keep Your Fridge Full
Turns out, always keeping your fridge full of food can actually be good for your wallet! Food acts as insulation and helps your fridge keep food items cold. Every time you open the fridge door, you introduce warm air into it. If you already have a lot of chilled food items in your fridge, they will retain cold air and that warm air will have less of an effect. On the other hand, if your fridge is always empty, the large amount of warm air that enters every time you open it has more of an impact and it has to work harder to keep cool.
Why Is My Electricity Bill So High All of a Sudden?
If you already follow all the tips given in this article, yet your electricity bill has suddenly skyrocketed, there could be a few reasons:
6. Electricity Leak
If your bill is suddenly higher than usual, an electricity leak could be to blame. An electricity leak occurs when electricity flows to the earth through the earth wire, usually due to faulty wiring. An electric leak can be expensive and dangerous. If you turn off the main breaker for your house and your electric meter is still showing electricity consumption, you may have a leak. If you suspect a leak, contact a licensed electrician immediately. Do not attempt to fix it yourself as you can get a nasty electric shock.
7. Rising Inflation
Your electricity bill may sometimes increase for reasons not under your control. If there is overall inflation in the country, naturally, your electric bill will also increase. Unfortunately, there is not much you can do in this situation. However, you can be even more diligent about not wasting electricity and reducing your consumption as much as possible.
8. Someone Could Be Stealing Your Electricity
A sudden unexplained increase in your electricity bill could be caused by pilferage. Switching off the main breaker is a simple and easy way to determine if someone is stealing your electricity. Contact the power company immediately if your electric meter continues showing electricity usage. They will send a technician to resolve the issue.
Which Appliances Use The Most Energy In A Home?
Heaters use the most energy in a home. They account for the highest percentage of a home’s total electricity consumption. Water heaters and cooling appliances are the second and third biggest consumers of residential electricity, respectively.
Does Unplugging Appliances Save Electricity?
Yes, unplugging appliances does save electricity. The average household has 40 products constantly drawing energy. Combined, these can amount to 10% of total residential electricity use. High electricity bills are a source of great financial stress and hardship. With these tips, you can reduce the burden on your wallet and benefit the environment. It’s a win – win! Start implementing these tips and enjoy big savings in no time!
According to WHO, the indoor temperature should be between 18 C – 23 C during winter. If you have children, the elderly, or people with health issues, the minimum temperature should be above 20 C degrees. If your indoor temperature falls below this range, it may be time to turn the heat on!
The WHO recommended temperature value above may not cater to everyone. You may have a different comfort threshold. If you are someone who doesn’t feel that cold, even if it’s below 18 degrees, you don’t have to turn on the heat. You can continue saving energy! On the other hand, if you feel chilly and uncomfortable when it’s 25 C indoors, you can definitely use your heating unit. Your personal comfort should be your top priority.
The ideal sleeping temperature is accepted to be around 18 C. For a comfortable sleep, it is recommended to keep your thermostat set between 15 – 19 C degrees.
In case your bedroom temperature goes below 18 C at night, you can turn on the heating system for a few hours. To save on energy, try turning the thermostat back 7 – 10 degrees from your daytime settings. For instance, if your thermostat is set to 20 C during the day, you can lower it to 17 C at night. You can also use warm bedding and a blanket to keep yourself comfortable without cranking up the heat.
What Is The Best Thermostat Setting For Winter?
The ideal thermostat settings for winter are between 20 – 22 C when you are at home. This range is a perfect balance of comfort and energy savings. You can save even more when you are away or sleeping by turning the thermostat back 7 – 10 degrees from your usual temperature settings.
Tip: Manually adjusting the thermostat for separate daytime and nighttime settings can be a hassle. A smart thermostat or a smart AC controller that works with a mini – split, window, or portable heat pump can help automate your home climate. With these smart devices, you can easily set schedules, and your temperature settings will be applied automatically at your set timings.
What To Do Before Switching On Your Heating System
Before turning on the heat, you need to take a few important steps, like checking the heating system and making sure your house insulation is at par. With the proper preparations, you can easily stay warm and cozy in the winter season.
Upgrade Your Thermostat
Find & Fix Air Leaks
You might not pay attention to small air leaks, but they can significantly affect your home comfort and energy bills in the longer run. Cold air can infiltrate your home through cracks and gaps, while hot air from your HVAC unit can easily leak out. Finding and fixing air leaks in your home can help lower your energy costs by an average of 15%.
Drafts are commonly found around doors, windows, pipes, floorboards, chimneys, ductwork, and wiring holes. You can use caulk to seal small gaps around your home. To fill in the leaks in doors and windows, apply weatherstripping. Silicone – based filler can be used to fill the cracks in your floorboards. Also, check for leaks around your air ducts. You can use foil tape or apply duct mastic to cover the duct holes and prevent heat from seeping through.
Perform Tune – ups
One of the best ways to ensure your unit is running at its best is by performing regular HVAC tune – ups. This means cleaning AC filters and checking for any signs of damage, leaks, or wear and tear. If necessary, schedule a maintenance check with a professional technician. This helps detect any issues, such as unusual HVAC smells or sounds.
Test Run Your Heating System
After you have performed the tune-ups, do a practice run before it gets cold. This helps to detect any issues early on and prevents you from suffering in the cold due to a faulty HVAC system.
Increase Your Home’s Humidity Levels
As the temperature drops, the humidity levels also plummet. And when you are going to turn the heating unit on, it is going to further strip the moisture from the air. Dry winter air can cause various health issues like an increase in allergies, dry skin, respiratory problems, and nose bleeds. Moreover, it can also pose damage to your wooden floor, furniture, and walls. To increase humidity in your home, you can bring in houseplants, air dry your clothes or invest in a humidifier.
Check Safety Alarms
Smoke alarms are one of the most important safety devices in your home. In case if anything goes wrong when heating, you need your smoke alarm to work. In order for them to perform their job, they require routine maintenance. Not regularly checking your smoke alarms increases the possibility of their failure, and that can put you in harm’s way. So, it’s best to test your smoke alarms before the heating season starts to ensure they are working fine. If your alarm or the detector uses a battery, check if it needs replacement.
How To Delay Putting The Heat On?
Due to increasing power prices, you may be reluctant to turn on your heater until you really need it in a bid to save on bills. However, you don’t have to feel uncomfortable in your own home. Here are some steps you can take to keep yourself warm without any compromises. You can also apply these tips to make your home more energy efficient when the heating is on.
Let the Warmth In
To improve warmth in your home, consider opening your drapes or blinds in the morning to let the sunshine in. This will help accumulate heat during the day, and you can close them at night to retain warmth.
Invest in a Room Heating Unit
Running your central HVAC system in the fall may lead to energy wastage as your whole house may not require heating. A better way to keep warm without driving up the bills is to perhaps invest in a small space heating, portable heat pump, or consider HVAC zoning. The best part about portable heat pumps is that you can move them from one room to another when needed. It works like any other heat pump by drawing in heat from the outside air, then circulating it inside.
Get Thermal Curtains
Thermal curtains can trap the air between the different layers of fabric, providing an insulating effect. This means that the temperature outside will not affect your indoor environment.
Layer Your Clothes
Putting on some extra layers is an obvious way to regulate your body temperature and stay warm without a heater. A sweater or a cardigan can definitely keep you comfortable on chilly fall evenings, allowing you to save the big switch for a later date.
Use Floor Rugs
Floor rugs have long been valued as an aesthetic element, but beyond their decorative function, they serve a practical purpose, helping to minimize heat loss. Floor rugs work by trapping tiny pockets of air between the rug fibers, slowing down the flow of heat from one side of the rug to the other. So, invest in a thick rug with a high stitch count; your feet will surely thank you.
Make Use of Draft Stoppers
Using a draft stopper at the bottom of the doors and windows is one of the simplest ways to keep your home warm. This prevents cold air from seeping into your home.
What if Your Heating Unit Doesn’t Turn On?
Sometimes, when you turn on your heating unit after a long summer, it doesn’t function properly. Here are some troubleshooting tips to help you deal with heating problems:
Check Your Thermostat – One common issue why your thermostat isn’t working is lack of power. If your thermostat is battery-powered, try replacing the batteries. For hardwired systems, check the circuit breaker and reset it if it has tripped. Also, check for blown fuses and call an HVAC technician for replacement if that’s the case. If that doesn’t solve the issue, try resetting your thermostat.
Clean Your AC Filters – The AC filters need regular cleaning for efficient performance. If you haven’t inspected them before turning the heater on, your unit may have trouble functioning properly.
Check Your Outdoor Unit – When your heating unit isn’t used during the summer, dirt and debris can get stuck in the outdoor unit and cause issues. Clean the outdoor unit before turning the on unit. Also, trim vegetation around it to prevent leaves or twigs from getting inside.
Remove Obstructions – Move furniture pieces that are blocking the vents so there is no airflow issue and warm air can easily circulate around. Also, ensure your thermostat is not behind a curtain or a furniture piece, as this blocks airflow, leading to incorrect temperature measurements.
Deciding To Turn On The Heater
If you are wondering when it’s time to start warming up in the fall, just keep in mind that there is no hard – and – fast rule for when to turn on the heater. Whether you choose to leave it off until temperatures drop significantly or turn it on as soon as fall hits is a personal decision that depends on your specific situation. If you are looking to save some bucks before the freezing weather, you can delay turning on the heat by letting the sun in, weatherizing your home, or sliding into a cozy blanket. And once you have decided that it’s time to crank up the heat, be sure to invest in smart climate control devices to keep your heating bills in check without compromising on your comfort.
Ever – increasing electricity bills are a great source of frustration and economic insecurity. With the extreme changes in the climate, it seems like no matter what you do, you can’t keep up with the skyrocketing electric bills. However, don’t lose hope just yet! There is a lot you can do to lower your electric bill. For example, switching to a smart thermostat or smart AC controller for automated heating/cooling can save you a lot on bills. Read ahead to find out why your electric bill is so high and how you can get it under control. With these handy tips, you will be saving big bucks in no time!
Causes Of A High Electric Bill
While you may think you are doing all you can to save electricity, you may have picked up some unfavorable habits over the years that are making your electricity bill skyrocket.
1. You are lazy about AC maintenance
Air conditioning costs account for 17% of total home electricity expenditures. In more humid climates, this figure increases to 27%. Neglecting maintenance can make this number grow exponentially. For example, if your AC filters are blocked, your air conditioner will have to work harder to provide the same level of cooling, thus consuming more electricity. Moreover, regular AC maintenance will also save you expensive repairs down the line.
2. You Have Leaky Doors and Windows
Windows and doors are major sources of air leaks. Even when your walls are well – insulated, if the weatherstripping or caulking on your doors and windows has worn out, your air conditioner or heater will struggle to do its job properly. As a result, it will have to work overtime, leading to an increased electric bill. Before you start loading up on caulk and weatherstripping, it’s important to know exactly where the air leaks are. Read this handy blog on finding and fixing air leaks to ensure your electricity bills stay as low as possible.
3. You Use the Most Energy During Peak Times
If you have been wondering why your electricity bill is so high despite limiting your usage, look at when you consume the most electricity. Electric companies charge higher rates during peak times to limit excess energy consumption. Therefore, if your electric bill is still too high, you can save your electricity bill by not using the electronics at the same time as everyone else!
In summers, peak hours are usually between noon and 6PM when everyone is blasting their aircon units at full. Simply limiting usage during this time, or running your AC at a higher temperature, can make a difference and help you lower your electric bill. Other than the aircon unit, avoid using the washing machine, vacuum, dishwasher, and other appliances at peak hours to keep your energy consumption in check.
4. Your Home Is Inadequately Insulated
Inadequate insulation could also be the reason why your electric bill is so high. As a general rule, heat travels from areas with a higher temperature to areas with a lower temperature. Consequently, indoor heat is trying to escape outdoors in the winter. As a result, your air conditioner struggles to maintain a cooler temperature during the summer, and your heater struggles to maintain a warmer temperature during the winter. Proper insulation prevents heat transfer through conduction, convection, and radiation – making it easier for your air conditioner to maintain your desired temperature. Your AC no longer has to run overtime to heat or cool the room. This saves energy and prevents a high electric bill.
5. You Have an Old HVAC System or Other Old Appliances
Old air conditioners use a shocking amount of electricity. An average air conditioner can last for 10 – 15 years. After that, as they get older, individual parts, such as the compressor, become less efficient. Older compressors use considerably more electricity. As Energy Star regulations become stricter, newer air conditioners have a much higher EER and SEER rating than older ones.
Apart from air conditioners, older appliances, such as refrigerators or washing machines, can be massive energy hogs. Natural wear and tear decrease the efficiency of older appliances, and they have to run overtime and draw excess electricity. As technology improves, newer appliances are becoming more efficient. An old refrigerator consumes 35% more energy than an Energy Star certified refrigerator. Get rid of appliances when they have reached the end of their lifespan. If you don’t, you will spend more on expensive electricity bills.
6. You Run Your Hot Water Heater at a Very High Temperature
Your water heater’s temperature could be why your electric bill is so high. Water heaters account for 14 – 18% of your total utility bill. Thus, you can save a lot on your total electricity bill if you cut down on water heater costs. But unfortunately, most households keep their water heater at a higher temperature than required. Most water heaters come with a preset temperature of 60C. However, experts say you can safely set them to a temperature of 50C. Setting your water heater at a lower temperature will reduce energy consumption and prevent scalding injuries!
Another ingenious method of saving money on your water heater bill is insulating it with a water heater blanket. This will prevent heat loss, and the water heater will not have to work hard to maintain the desired temperature.
7. You Keep a Spare Fridge
Many people like to keep a spare fridge in the basement, unaware that it could be why their electric bill is so high. However, even if you are not using your extra fridge, it consumes energy if plugged in. If your spare fridge is mostly empty, consider if you need it at all. If you must keep an extra fridge, ensure it is always full of something, or unplug it. So the next time you wonder why your energy bill is so high, look at the spare fridge lying in the basement and consider flipping it.
8. You Still Use Incandescent Light Bulbs
If you are still using incandescent light bulbs, they could be the main culprit behind your high electric bill. Incandescent light bulbs consume a lot of energy compared to LED bulbs. It is estimated that the average household could save €200 per year by switching to LED bulbs. Not only are LEDs cheaper, but they are also very long – lasting. Once you invest in them, you won’t have to change your lightbulbs for years. So what are you waiting for? Make the switch now!
9. You Frequently Use the Dryer
Using the dryer for every load of clothes is a major cause of high electricity bills. A simple clothesline can make a drastic difference if you want to lower your electric bill. Each hour of using a dryer costs anywhere between 24 and 72 cents. So if you use your dryer for every load of laundry, the cost can quickly add up. To avoid these costs, whenever the weather is good, skip on the dryer and hang the clothes outside to dry. Your wallet will thank you!
10. You Cool Your Entire House Even When You Don’t Need to
Most people only occupy 1 – 2 rooms at a time. However, they still turn on the air conditioning for the entire house. This is a massive waste of electricity and leads to excessive bills. To get around this dilemma, you can create HVAC zones. HVAC zones use dampers to let you divide your house into zones and set a different temperature for each. Your AC will no longer have to work unnecessarily to cool your entire home.
11. You Use Your Dishwasher and Washing Machine Too Frequently
Appliances such as dishwashers and washing machines are notorious energy hogs. Apart from their energy consumption, they also need loads of hot water, thus increasing your water heater usage. Fortunately, saving money on washing machines and dishwashers is very easy. You just need to be a bit more responsible. For example, never run your dishwasher for a small load of dishes. Instead, wait for it to fill up completely, then run it at the end of the day. You also don’t need to run your washing machine every day. Instead, keep a designated day or two to do the entire week’s laundry. These simple and easy steps will greatly help you lower your electric bill.
The HVAC industry has massively progressed since the invention of the first electric furnace in 1861. From burning wood to next-gen AI-based automated heating systems, the race toward highly intelligent, fully automated HVAC technologies is still on. New players are entering the scenario and taking the game of innovation to the next level. Technology is without a doubt a major contributor to the growth of the HVAC industry. It is playing an important role in satisfying the growing demand for energy-efficient solutions. The global HVAC system market is expected to grow from USD 202 billion in 2020 to 277 billion by 2025.
While the initial development in HVAC technology focused on mechanical advancements and increased efficiency, the current focus has also majorly grown towards sustainability, comfort, and energy-saving. This is extremely important considering the current impact on our climate and the rise in demand for efficient heating and cooling systems. Let’s take a look at some of the latest advancements in technology that are taking the present day HVAC system towards a brighter future.
1. Smart HVAC Technology- Automation is the Way Forward!
Think of your air conditioner automatically turning on exactly 15 minutes before you reach home from work. Whether you achieve this through scheduling or geofencing, smart technology offers ample convenience allowing you to set triggers and control your HVAC system from your mobile device. With these Wi-Fi connected devices, you don’t even need to be home to send commands to your unit!
Smart ACs, smart controllers, and programmable thermostats offer numerous benefits. Along with comfort and convenience, you can achieve energy savings by setting triggers to activate your HVAC unit exactly when you need it. This ensures that the unit would not be running unnecessarily throughout the day and thus saving energy.
With smart technology, completely automated homes are also becoming a reality. Now, your HVAC unit can be connected with other smart appliances in your home and behave automatically based on climate conditions, preferences, and settings. As an example, when it’s sunny and hot outside your blinds may turn halfway down, the AC may turn on a cool, low fan setting to preserve energy while your ceiling fan can turn on to circulate air at low power. Moreover, you can also give voice commands to your air conditioning unit. All appliances can be interconnected and adjusted according to each other!
2. Geothermal HVAC Systems – Sustainable Technology
Sustainable or green technology is the talk of the present and the future. In the HVAC industry, this means keeping the natural flow of air in mind and relying on a more efficient system.
Geothermal heating and cooling systems are an excellent option to start reducing your carbon footprint. Their major emphasis lies on naturally cooling a house using heat pumps, water, and an underground piping system. They exchange heat with the ground and no refrigerant is used, which makes them highly environmentally friendly.
During winter, the heat from the ground is absorbed and transferred into a building while in summer the heat is transferred to the ground after being absorbed from the building. Geothermal systems are expensive to install but they deliver double to four times the efficiency of other systems.
3. Ductless HVAC Systems – Efficiency & Savings
Energy efficiency is the key to the HVAC systems of the future. Ductless systems are quickly becoming the system of choice as they are super efficient and their installation does not involve extensive ducts. This makes them easy to install and cost effective.
Another benefit of ductless systems is their zoning capability. In the case of a ductless system, you do not need to heat or cool an entire home, but you can simply heat or cool a particular zone. These systems are very efficient with great seasonal efficiency ratings.
Ductless HVAC systems can be installed from moderate temperature zones to harsh temperature zones. The already efficient ductless system can be made more efficient by the use of smart AC controls. These smart AC controls are brand and type independent and you can control your ductless system from anywhere. Moreover, users can benefit from intelligent smart AC features such as geofencing, scheduling, comfy mode, and more.
4. Thermally Driven Air Conditioning – Go Solar
Thermally driven air conditioning is a new HVAC technology picking up on the need for sustainable systems. It provides an energy-efficient cooling method and can be used as an alternative to traditional air conditioners. Instead of electricity, this system utilizes solar energy for cooling, and if unavailable then natural gas kicks in. This completely eliminates electricity costs!
While this HVAC technology is not extremely widespread, it is a great glimpse into an eco-friendly future. Thermally driven air conditioning systems remove heat with evaporation at low pressure. They are extremely effective and efficient however a high temperature (around 350F) is required to generate electricity from the solar panels.
A dual fuel heat pump is an excellent system for homes in areas where the electricity rates are not too high and during winter the temperature does not fall below freezing point. This advanced HVAC technology utilizes a combination of a gas furnace and a heat pump to provide efficient, cost-effective heating and cooling.
If the outdoor temperature is above 35 degrees, the heat pump utilizes electricity to pull in heat from the outside air. This is extremely cheap compared to firing up the furnace. Although, once temperatures are below 35, gas is used to create heat for higher efficiency.
When the weather is cool, such as in spring, the dual fuel heat pump comes in handy to distribute air. Even during summer, the heat pump circulates the refrigerant through the furnace’s air conditioning coil to blow cool air! This system has a high upfront cost but this can be recovered through energy savings over the next few years.
6. Zoned HVAC System – Customize Temperature According to an Area
An HVAC zoning system divides a house into different areas, each of which can be individually controlled by a separate thermostat. Different temperature settings may be required in different parts of a home and by utilizing zoning you can achieve the best temperature for each area. This is especially important to decrease usage in empty rooms. Zones can be applied to central air conditioning systems, VRF systems, or ductless systems. Zones can easily be installed in existing systems also by utilizing a zone control panel. Apart from the latest innovation in HVAC technology, the latest trends in HVAC service and service delivery are also helping both the service providers and the end-users. Here are the latest trends in HVAC service delivery:
7. Predictive Maintenance – Stay Alert
Predictive maintenance, utilizing IoT and AI is revolutionizing the upkeep and maintenance of HVAC technology. HVAC repairs, maintenance, and installations can be extremely costly. Nobody wants to go through unnecessary maintenance nor take on the hassle and cost of fixing an issue. This makes it imperative to stay alert and be able to predict when maintenance is needed before a serious issue arises!
Smart HVAC technology senses data on air quality and equipment status to be able to predict the right time for maintenance. This helps to fix any problem or indication before it has already occurred and caused serious damage. Other than monetary benefits you can greatly benefit from improved air quality at all times and better comfort and a safer home with predictive maintenance!
8. HVAC Energy Analysis Software – Make Informed Decisions
Energy analysis software can be extremely useful in helping owners or constructors to implement the most efficient and least costly HVAC system. This software can analyze and predict a building’s lifetime energy use and calculate savings in comparison to other HVAC systems.
Furthermore, previously HVAC users had to keep a check on their bills, energy consumption, and other related data manually. It was a hassle but with the advancement of HVAC technology, analytical software helps you to stay on top of any data related to your HVAC system. Through various software, you can check your energy consumption and track the efficiency of an HVAC system. This is greatly helping consumers make educated decisions concerning their HVAC system and cut down on energy costs.
9. Virtual Reality – Training for HVAC Professionals
While viewing advancements in HVAC technology, it is also important to note the developments in technology for training HVAC professionals. In an era where you can get assistance from HVAC professionals remotely, HVAC professionals can also benefit from technology and can be trained for exceptional circumstances through virtual reality.
Virtual Reality training has proven to be cost-effective for organizations because professionals can first use virtual components and develop their skills before moving to the real world. It doesn’t only save money but saves time as well. With the help of a virtual simulator, technicians can look into the process of installation of the HVAC system or troubleshooting of the new system. A large group of people can be trained through virtual reality in lesser time and with less equipment.
Furthermore, for advanced or dangerous technology, VR training also provides safety for beginners. It can also be a great tool to practice real-life, dangerous situations. Virtual reality is not the only application for training, it’s growing to find its purpose in many more use cases also!
The Future of HVAC Technology
From manual buttons, dialers, remote controls to controlling your HVAC system via voice commands, technology has come a long way.
HVAC is bound to embrace new technologies. The smart home trend is here to stay. AI in the form of machine learning is going to thrive. Fully automated, super-efficient, self-learning and sustainable HVAC systems are the future. Optimization in every aspect of the supply chain is the new normal.
If running costs and safety are important to you then a swimming pool cover is an essential consideration for any pool, indoor or outdoor. Amazingly evaporation causes 70% of pool heat loss. A cover helps to prevent heat loss by sitting on the water, minimizing air contact and stopping your pound notes escaping into the atmosphere.
Another benefit is maintenance becomes less time consuming as the cover decreases the amount of dust or leaves entering your pool, giving you more time to enjoy your swimming, and less time to resent the cleaning.
So what kinds of covers are there?
There are four main types of pool cover:
Geobubble / Solar cover
Isothermic / Foam cover
Blade / Slatted covers
Winter / Safety covers
The majority of our clients choose the Geobubble Solar cover with Blade/Slatted covers being the premium option when you want design and functionality combined.
What is a Geobubble™ Solar Cover?
Bubble covers are made from two types of polyethene film. One flat level and one bubble level which enables the cover to float. It is the ‘value-for-money’ option, since it minimizes evaporation, heat loss and debris entering your pool. It is also the fastest to be delivered in just 3-5 working days upon order and we can make it bespoke to fit exactly your pool needs.
Bubble covers are traditionally manual; thus we recommend a roller to ease your life when putting the cover on and off your pool before you swim. A reflective (protective) cover is also recommended to be placed on top of your solar cover after your swim to protect it from the sun!
What is an Isothermic/Foam Cover?
An Isothermic/Foam cover is considered to be the most suitable for heated pools, due to its isothermal qualities and long lifespan when used intensively in private/public pools and spas.
It is the ‘dedicated’ option in the solar cover family for minimizing heat loss. It also has the same delivery time in just 3-5 working days upon order and can be made bespoke to fit exactly your pool needs.
What is a Blade/Slatted Pool Cover?
A slatted pool cover consists of a series of PVC or polycarbonate slats that float on the surface of the pool. The slats sit on a motorized reel, housed in a cover pit, cover cave or a special bench, meaning there is no ugly manual pool reel at the end of your pool.
Like most automatic covers, they are usually operated by turning a key switch which clients often locate in view of the pool.
In terms of achieving a balance of excellent thermal efficiency, aesthetics, ease of use and longevity, a blade/slatted cover is what we believe is best suited to most luxury pools. It has better U-values than most other cover types and the ability to conceal it under paving or a deck when rolled up makes for a far nicer appearance.
PVC slats are the more cost-effective of the two options and come in a variety of colors. Polycarbonate slats are tougher, more resistant to heat, have a longer warranty and more available colours, but they also have a higher ticket price, being on average 20% more expensive than the PVC option.
What is a Winter/Safety Cover?
One of the most important things to bear in mind for families with younger children and pets is safety.
Safety covers are comprised of high-strength PVC reinforced fabric which is fixed to an aluminum “leading-edge” bar which pulls the cover along the width of the pool. Safety covers should be strong enough to endure any accidental slips, even by an adult. The fabric has a high gloss lacquer on both sides and contains a high tensile polyester scrim reinforcing layer to guard against tearing.
The material has a life expectancy of approximately 7-10 years. Apart from UV and wear & tear, the most common cause for a reduced fabric lifespan is the incorrect use of pool chemicals.
More than a third of the world’s population lives in drylands, areas that experience significant water shortages. Researchers developed a low-cost gel film made of abundant materials that can pull drinkable water from the air in even the driest climates.
The researchers developed a low-cost gel film comprised of abundant materials that can pull water from the air in even the driest climates. The materials that facilitate this reaction cost just $2 per kilogram, and a single kilogram can produce more than 6 liters (~1.6 gallons) of water per day in areas with less than 15% relative humidity and 13 liters (~3.4 gallons) in areas with up to 30% relative humidity.
The research builds on previous breakthroughs from the research team, including the ability to pull water out of the atmosphere and the application of that technology to create self-watering soil. However, these technologies were designed for relatively high-humidity environments.
“This new work is about practical solutions that people can use to get water in the hottest, driest places on Earth,” said Guihua Yu, professor of materials science and mechanical engineering in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering. “This could allow millions of people without consistent access to drinking water to have simple, water generating devices at home that they can easily operate.”
The researchers used renewable cellulose and a common kitchen ingredient, konjac gum, as a main hydrophilic (attracted to water) skeleton. The open-pore structure of gum speeds up the moisture-capturing process. Another designed component, thermo-responsive cellulose with hydrophobic (resistant to water) interaction when heated, helps release the collected water immediately so that overall energy input to produce water is minimized.
Other attempts at pulling water from desert air are typically energy-intensive and do not produce much. And although 6 liters does not sound like much, the researchers say that creating thicker films or absorbent beds or arrays with optimization could drastically increase the amount of water they yield.
The reaction itself is a simple one, the researchers said, which reduces the challenges of scaling it up and achieving mass usage.
“This is not something you need an advanced degree to use,” said Youhong “Nancy” Guo, the lead author on the paper and a former doctoral student in Yu’s lab, now a postdoctoral researcher at the Massachusetts Institute of Technology. “It’s straightforward enough that anyone can make it at home if they have the materials.”
The film is flexible and can be molded into a variety of shapes and sizes, depending on the need of the user. Making the film requires only the gel precursor, which includes all the relevant ingredients poured into a mold.
