Solar Powered Air Conditioners: A Comprehensive Guide

The Sun has been a source of energy in our cosmic system for billions of years. The history of humans using the Sun as an energy source is as old as mankind itself. It helps to grow food, for warmth, for fire, and for other uses across different continents. With the passage of time and advancement in technology though, we have been able to harness the immense potential of the sun in the form of photovoltaic cells and use it for much greater purposes. The Sun’s rays can now be converted into electricity, and be used to power our homes and appliances at a fraction of the environmental impact as compared to conventional sources. In this era of sustainability, this serves as a major driver for the growth of solar power.
What started as a niche application of this concept, has now turned into mass scale implementation of solar power. One such application of this renewable energy source is in air conditioning, through solar air conditioners. These heating and cooling appliances can work by using the sun as an energy source. Reduced energy bills and minimal environmental impact are just some of the benefits which this energy source provides. If you are like most homeowners and your air conditioner is powered by electricity from the grid, it’s likely that you will notice an increase in your bills considering the recent energy price hike. With solar – powered air conditioners you can harness the sun’s natural energy to maintain an ideal home climate while saving on energy bills. Let’s read on and find out all there is to know about solar air conditioning.

Why We Need Solar Powered Air Conditioners?

Solar powered AC.

With solar – powered AC units, you may still need to use electricity from the main power grid, but your consumption will drop up to 50%, depending on your climate. So, with solar power AC, you can save tremendous amounts of money on AC bills. This also helps to offset the initial high installation costs of solar panels Switching towards solar powered central air conditioning or installing solar powered window or portable air conditioners can be a great step towards fighting the current climate crisis.

Benefits of Solar Air Conditioning

The solar panel air conditioners provide several advantages. The only downside is that they require a high initial investment.

1. Increases the Value of Your Property

In addition to environmental benefits, solar panel air conditioners can also help increase the value of your home. The buyers are willing to pay more for homes with solar air conditioning.

2. Saves on Bills

With solar – powered AC units, you may still need to use electricity from the main power grid, but your consumption will drop up to 50%, depending on your climate. So, with solar power AC, you can save tremendous amounts of money on AC bills. This also helps to offset the initial high installation costs of solar panels.

3. Reduces the Energy Demand

Conventional AC systems operating during the hottest days can overload the electricity grid, leading to power outages in summer. Solar air conditioners are particularly helpful as they lower the demand during peak usage by shifting the load from the main grid. This can help reduce the frequency of power blackouts and brownouts.

4. No Greenhouse Gas Emissions

As solar energy is a renewable source, the solar power air conditioning units reduce the dependence on fossil fuels. This, in turn, helps to lower the emission of greenhouse gasses that contribute to global warming.

Even with solar – powered air conditioners, there are a few different options available. These differ based on the mode of power that the air conditioner is getting. Let’s see them below.

  • DC Powered Solar Air Conditioners

Also known as conventional solar – powered air conditioners, DC solar air conditioners run on direct current (DC) electricity, meaning that the solar panels are directly wired to it. They can run through the batteries, which are charged through solar power; therefore can run entirely off – grid. They use solar panels, photovoltaic panels to collect sunlight and turn it into electric energy. This type of air conditioner provides a few major advantages, which are:

  • As a solar panel produces DC electricity, running such an air conditioner directly off the solar panel will not be a problem.
  • DC – powered solar air conditioners are the go-to option for complete off-the-grid living and you can run them with minimal extra equipment cost, as in AC – powered air conditioners.
  • They are easy to install and maintain.

The disadvantage of such a system is that you would need a hefty battery bank to supply power for night time operation. The other option is to use a rectifier device to convert the AC electricity from the power mains to DC and then run the air conditioner. Still, it defeats the whole purpose of a solar – powered air conditioner!

  • AC Powered Solar Air Conditioners

Alternating Current is the more well – known solar air conditioner. For AC air conditioners to run with solar power, you need a device known as an inverter, converting the DC from the solar panels into AC. The inverter is an integral part of such a setup. Moreover, the solar powered air conditioner then uses up the energy stored in a battery after passing through the inverter. Due to this reason, AC powered solar air conditioners provide the following advantages:

  • These air conditioners can also be tied up to the grid power and run as a standard air conditioner. You don’t require an extra equipment since this air conditioner can run on AC power.
  • The primary advantage of such a system is that you can run it with grid power and solar panels.
  • If these ACs are tied to the grid, you can give excess electricity produced back to the grid and get credits for it by a process called net metering.
  • Hybrid Powered Solar Air Conditioners

Hybrid solar-powered air conditioners can run on both DC and AC at the same time, seamlessly. Such units can be connected to both the solar panels/batteries directly and to the grid at the same time. The unit can then use the appropriate power source according to the time of day and power load.

  • There is no additional equipment, such as an inverter, which means the total costs are also less.
  • They can switch between solar power and grid power smoothly.
  • They are very flexible to operate during all times of the day and seasons.

The disadvantage of this system is that if your batteries are not charged and installed it off-grid, it won’t work at night.

How Does a Solar AC Work?

A solar air conditioner combines solar electricity and air conditioning. In simple words, it takes energy from the Sun and uses it to power your AC to cool your space!

A solar panel is a device that captures the power of the Sun. It converts the Sun rays into electrical energy. This energy can then be used directly or stored in a battery. This is known as DC power. A solar – powered air conditioner then uses this DC power, either directly as DC or after conversion into AC (using an inverter), and heats or cools your home. Instead of using grid energy, a solar – powered air conditioner uses the energy of the Sun. It can use the grid energy, though, if needed.

The solar AC units collects energy in two ways: photovoltaic (PV) systems or solar thermal systems. Solar PV systems use photovoltaic panels to generate electricity, while solar thermal systems work like solar water heaters. They use up the sun’s energy to heat up water which then changes the refrigerant into a heat-absorbing gas that provides air-conditioned air to your home.

Factors to Consider When Shifting to Solar Powered AC

Here are some factors to consider when choosing a solar power air conditioner for your home.

  • Climate Conditions

Areas that receive more sunlight around the year and have longed summer season will only require a few solar panels. On the other hand, if you are in a location that gets less light will need more panels and a bigger battery for backup to harness the sun’s energy.

  • Size of Your Home

If your home is larger, it will need more AC capacity for air conditioning the entire space. So, you will need more solar panels as compared to a smaller area. On average, most homes need 10 to 20 solar panels to cover all the electric appliances.

  • Battery

If you live in a mild climate that doesn’t get much sunlight, it’s best to invest in batteries. Opting for batteries is also a good idea if you want to go completely off – grid so you can store solar energy for the night and on cloudy days.

What Is the Make Your Solar Powered Air Conditioners Smart

Saving energy with solar powered air conditioning is one step; save even further with smart air conditioning! Pair your mini – split, window, or portable air conditioner with a smart AC controller for home climate automation and greater savings. Smart AC controllers can help you save up to 25% on electricity bills. Moreover, you can also control your solar – powered AC unit from anywhere using your phone, set weekly schedules, enable geofencing or set other intelligent triggers for your home cooling and heating!

Is Switching to Solar Air Conditioning Worth It?

Solar-powered AC’s can be a game – changer. With modern, efficient air conditioners, powering through solar energy is becoming more simple year after year. Considering environmental benefits, energy savings, and tax credit, solar powered air conditioners are an exceptional choice for heating and cooling requirements.

7 Affordable, Stylish Gunite Pool Features to Consider

Are you planning a gunite swimming pool and want beauty and functionality—without busting your project budget? The good news is that an affordable gunite pool can have style and personality too. While the sky’s the limit on how much you can spend customizing a gunite design, no one has to. A number of features are not only attractive and functional, but reasonably priced. As you research inground pool prices, here are seven features to consider. Every one of them will add visual intrigue and pleasing aesthetics to any aquatic resort. The final cost of each will depend on the size, style, quantity, and local pricing in your local market.

1. Multicolor LED Lighting

One low-cost, “brilliant” idea for enhancing your pool’s appearance relates to how you illuminate it. In recent years, the advent of LED pool lights has been a game-changer. Using light-emitting diodes, this technology transforms any pool with an array of vibrant colors each evening. With the touch of a button, you can “paint” your pool & spa in a single color—not only white and blue, but in green, gold, pink, or purple. For even more drama, set the LEDs to rotate through a spectrum of colors. But for the ultimate in scenery and ambiance, go for an LED “light show.” Preset, themed programs such as “Gemstone,” “Tranquility,” and “Cool Cabaret” cycle in hundreds of colors that flash and dance around your pool at various speeds. As a bonus, LEDs cost less to maintain than old-school incandescent pool lights. LEDs are incredibly energy-efficient, and they will ensure many years of dazzling performance.

2. A Bubbler—or Two or Three

Add a dash of frothy bling to your pool water. Bubbler fountains bring motion and interest to your aquatic retreat even when it’s not in use. Entertaining poolside? Just switch on your bubbler fountains for a lovely, soothing sight. Bubblers can go into a pool’s top step. But by far, the favorite location is a tanning ledge. Accenting the shallow ledge with one, two, or three of these fountains not only looks great, it provides a visual cue to recognize the ledge’s shallow depth. Bubblers are trending more than ever when it comes to modern pool design. With a low price point, these fountains can fit into most gunite pool budgets. The playful feature is priced low enough that you can add a pair or trio of them to enjoy. Splurge a little, and you can add LEDs to light them up when the sun goes down.

3. Cascade Water Features

For some splashy spirit, include one or more cascade water falls on your pool. These affordable fixtures emanate a small, continuous sheet of water that flows into the pool below. The plumbed fixture mounts to the pool’s “bond beam.” Bond beam is a section of pool wall that extends at least 6 inches above the pool. On the shortest bond beam—just half a foot—it’s possible to include one special kind. This particular style produces an arcing cascade. The water moves upward and out before falling onto the pool’s surface. However, the two other kinds are used far more frequently. One has a sheet that descends straight down in a sleek fashion.

The other kind produces a sheet that arcs; it travels several inches or more outward and over the pool before hitting the surface. To accommodate one of these common versions, the bond beam must be at least one foot high. The final cascade effect will be even better if the beam is 18 to 24 inches high. When it comes to width, most cascades run 12 to 18 inches. Custom versions span several feet. Although a single cascade looks great, many pool buyers prefer two or three mounted at set intervals across the bond beam. Most cascades will produce flat, sheer sheets of water. Their smooth surface will catch the sunlight and make them virtually shine. For a different cascade look, a broken “raindrop” style is also available.

4. Umbrella Via Sleeve

Bring comfortable shade and a bright pop of color to your pool area. Integrating a sleeve to hold an umbrella pole is a simple, effective way to make both possible. During construction, your builder can incorporate a hidden sleeve. Later, when your pool’s complete, pop in the patio parasol of your choice. Since the sleeve is always present, it’s easy to add or remove the umbrella as you wish. You can request one or more umbrella sleeves in various spots around your pool or spa. For example, the sleeve can be inserted into the pool coping around the spa. There, an umbrella can block some of the sun’s rays while you hang out in the bubbling water. However, the hands-down favorite approach is for sleeves to go into tanning ledges. Pool owners appreciate having an umbrella on the ledge for some sun protection. An umbrella sleeve is a genuine bargain. Once the sleeve is ready, buy a patio umbrella in any price range you like. Now you have a colorful, stylish, convenient way to beat the heat for minimal cost.

5. Raise the Spa

If you are already planning a gunite spa with your new pool, take it—literally—to the next level. Building a spa even just 6 inches above the pool will draw more attention. Raise the spa 12 to 18 inches, and it transforms into a bolder focal point. This added height enhances the spa’s aesthetics. Here’s how: As spa water overflows down a foot or more to the pool surface below, the spillway creates an attractive “water-in-transit” effect. As a bonus, some spillover designs generate soft gushing sounds as they hit the pool surface. But again, these wonderful effects are not possible with a spa that’s level with the pool or raised a mere 6 inches. A spa that’s at least a foot above the pool boasts another decorative treat: The spa will reveal its upper dam wall—the barrier that separates the spa water from the pool water. This section of exposed spa dam wall becomes a backdrop for showcasing colorful pool tile, specially arranged tile patterns, or decorative stone. Elevating your spa may also elevate your backyard experience. As you relax in the hot bubbling water, the higher perch provides a better view. From the comfort of your raised spa, you will enjoy the views across your pool surface, surrounding landscape, and any distant vistas.

6. Jets on Deck

How about some liquid “eye candy” along with an aural ambiance that your ears will appreciate? With deck jets, you will relax watching graceful streams gently hit your pool’s surface. These moving arcs glisten in the sunshine as their spray falls onto the water below. With several on a pool, you may hear lovely sounds as well. Pool deck jets project several feet upward, and some can go taller. As the emanating arc descends, the tubular shape diffuses and spreads into small droplets. Whether they accent a chic geometric pool, classic Roman/Grecian, curvy tropical lagoon, or any other pool style or pool shape you pick, deck jets will bring extra motion and character to the setting. Best of all, deck jets can be had for surprisingly little. With an economical price point, you can introduce one or more of these playful features into your pool and deck design.

Note: Avoid confusion between the modest deck jet and its high-cost cousin: a laminar. Equipped with its own motor, a laminar emits a highly uniform, glass-like arc. This pricier option can also be internally illuminated with LEDs.

7. Ready-made mosaics

If the Greeks and Romans could enjoy the beauty of mosaics, so can you! Now, handcrafted tile mosaics rank on the list of stunning, expensive pool features. It’s true, “custom” mosaics are essentially original works of art that command big price tags. However, you can achieve some of the looks of fancy mosaics—for a fraction of the cost. Many off-the-shelf mosaics are available for a gunite pool’s floor, walls, ledges, benches, and steps. These versions are easy on your wallet and come in colorful, whimsical, and sophisticated designs. The wide assortment of standard images will make choosing your pool mosaic big-time fun. Sea creatures such as fish, crabs, turtles, and dolphins are among the most popular.

Daikin Europe Lifts Patents On R32 in VRF Systems

Brussels, 1 July 2022 – Daikin Europe N.V. released its ‘HFC-32 PATENT NON-ASSERTION PLEDGE’ which will provide free access for the entire market to Daikin Europe’s 30 patents related to VRF systems combined with HFC-32 (R32) refrigerant. Providing this free access will further promote the use of the non-blended, single-component HFC-32 refrigerant in VRF systems, which has a lower global warming impact than R410A, the refrigerant conventionally used in VRF systems.

The decision of Daikin to provide free access to its patents happens against the background of global attempts to reduce the impacts of HFCs on global warming, especially now that the Kigali Amendment to the Montreal Protocol*1 is being translated into actual country regulations. For the European Union, the European Commission is currently considering an update of the existing F-Gas Regulation, which might result in stricter requirements for the use of refrigerants. Also VRF systems will be subject to the new regulation, if it comes into effect. VRF systems heat and cool large buildings such as offices, schools, hospitals and so on. To do this, multiple indoor units are connected to a single outdoor unit, and a closed refrigerant circuit flexibly moves through the system, allowing individual temperature control throughout the rooms of a building. The HFC refrigerant conventionally used in VRF systems is R410A.

The F-Gas regulation will force air conditioning and heating manufacturers to choose a refrigerant with a lower GWP. HFC-32 can provide a VRF solution with such a lower GWP refrigerant. This is where free access to Daikin’s patents can accelerate the adoption of HFC-32.

Mechanical Installations

‘Daikin comprehensively evaluates a wide variety of refrigerants and promotes the selection of the appropriate refrigerant for each application, and currently considers HFC-32 to be the most suitable refrigerant for VRF systems.’, says Martin Dieryckx, General Manager Environmental Research Center. ‘HFC-32 has many advantages that can help reduce the environmental impact of air-conditioning. HFC-32 is a non-ozone depleting refrigerant and its GWP is one-third*2 of conventional R410A refrigerant. It provides excellent system performance and is readily available. As a single-component refrigerant, it is easy to recover, recycle and reclaim, which reduces the need for additional production of virgin refrigerant.’

Kazuhide Mizutani, General manager of EMEA Research Center, says ‘The patents that Daikin Europe pledged not to assert include those relating to the control of compressor rotation speed and safety systems such as refrigerant leakage sensors. The Pledge will make it easier for other air conditioning and heating manufacturers to develop VRF systems using HFC-32. Furthermore, promoting the installation of safety systems in equipment reduces the burden on air-conditioning installers to inspect equipment.’

Daikin Industries, the mother company of Daikin Europe, has pledged the non-assertion of the patents in relation to applicable air conditioning equipment using HFC-32 from 2019 in order to contribute to the environment. Apart from Daikin Europe’s patents,  the company simultaneously pledged today the non-assertion of the new 90 patents. Daikin Group aims to make further environmental contributions worldwide. A list of the pledged patents and the specifics regarding the pledge is available here.

The Perfect Climate For A Good Night’s Sleep

Have you ever woken up with a dry mouth and a sore throat? Humidity levels in your bedroom are likely to have fallen below the internationally accepted threshold for a healthy indoor climate. But what exactly is the threshold? And how do you create the perfect atmosphere for a good night’s sleep?

Why does humidity matter?

Humidity is the concentration of water vapor in the air. The humidity level in your home can affect your personal health in many ways. Excessively high humidity, for example, is associated with higher concentrations of allergens, while exposure to excessively low humidity can cause health problems such as dry skin, itchy eyes and sore throat. Maintaining healthy humidity levels is important to make the bedroom a comfortable space and ensures a healthy sleep cycle for rejuvenation.

How can I ensure the perfect climate?

Humidity levels are usually measured by the relative humidity which is the ratio of water vapor in the air to the amount of vapor that can be present in the air at a given temperature. The best relative humidity for sleep has been a topic of discussion but most studies agree that the best indoor relative humidity is between 40 and 60%. If you usually wake up with a sore throat and dry eyes, the relative humidity level in your bedroom may have dropped well below the 40% threshold.

Ensuring a perfect indoor climate can be a challenge. In climates with extremely high humidity levels, it is a good idea to install an air conditioning system with a built-in dehumidifier . These systems automatically detect values ​​that exceed the preferred humidity level (usually starting at 60 ° C) and extract moisture from the air to achieve healthy humidity levels.

For extremely low humidity levels, installing an air purifier with a built-in humidifier can help achieve a healthier, more comfortable indoor climate. For example the ionizer with Daikin humidification function, injects moisture into the air when the relative humidity falls below the preferred level (usually starting at 40%) to maintain a healthy humidity level. Daikin air purifiers also minimize asthma and allergy symptoms by removing dust particles and pollen from the air, and Streamer technology keeps the air healthy and clean by eliminating allergens, eliminating bacteria and removing odors. This cleaning element separates ionizers with a humidification function from traditional humidifiers as traditional humidifiers tend to accumulate pollutants instead of eliminating them, allowing them to continue to reproduce and possibly cause disease. And what about the noise? The Daikin humidifier with built-in humidifier is extremely quiet thanks to a new innovative device and a state-of-the-art quiet operation, making it one of the quietest series of air purifiers on the European market. The perfect solution for a good night’s sleep while at the same time staying healthy, refreshed and feeling comfortable.

The unit also offers greater flexibility by having a low sound mode that reduces the sound pressure at 3 metres to 35 dBA, representing a real reduction of half the sound level!

The acoustic level can be evaluated in two ways

› The sound power is generated by the unit itself, independently of distance and environment

› The sound pressure is the sound perceived at a certain distance. The sound pressure is usually calculated at between 1 and 5 metres from the unit.

One solution, multiple combinations

The Quintessence range can be combined with three different indoor units to connect to the outdoor unit, offering specific features to ensure heating, cooling and domestic hot water in your home.

Outdoor unit

The outdoor unit is available in 6 classes 8-10-12-14-16-18 kW.

How to open up your pool after the winter

1. Remove cover

  • Wind up the pool cover carefully ensuring as few leaves and debris enter the pool as possible.

Mechanical engineering cyprus2. Clean the cover

  • Place the cover flat side up with the bubbles facing down.
  • If possible use the space available around the pool by setting the reel system back, creating a flat surface between the reel and pool.
  • Your cover can also be laid out on a lawn to be cleaned.
  • Rinse down with a hose or jet washer (ensure jet washer kept 20cm – 30cm from cover).
  • Use a soft brush to remove embedded residue.

3.Clear the pool of debris

  • Use deep net or skimmer net to clear leaves and debris from surface and floor of the pool.
  • Open and empty skimmer baskets, clean inside of skimmer.

4. Deep clean the pool

  • Use a soft pool brush to brush away algae and dirt off walls and floor of the pool.
  • Remove inlet cover plates and eyeball inlet nozzles and clean.
  • Vacuum the pool – run your robotic cleaner to remove the last residue at the bottom of the pool.

5. Top up water levels

  • Run hose line to the pool and bring the water level to the middle of the skimmer.

6. Set up the filter

  • Ensure pump is switched off and turn off inlets, main drain, and skimmer valves to pump and filter.
  • Open the lid to the pump remove the pump filter basket.
  • Clean the pump filter basket and reinstall.
  • Ensure the pump seal is clean and reinstall.
  • Use a bucket of water to help prime pump. Replace pump lid.
  • Open inlets, main drain, and skimmer valves to pump and filter.
  • Switch on pump for 24 hours, ensuring the multi-port valve is set to “filtration”
  • Backwash the pool filtration as required.

7. Check chemical levels and balance pool

  • Take water samples from the pool (ensure taken 20cm under the water level).
  • Check pH, Free Chlorine (FC), Combined Chlorine (CC), (calculate Total Chlorine (TC)), Calcium Hardness (CH) and Total Alkalinity (TA).
  • Take appropriate actions to balance pH, CH and TA (take time to allow chemicals to settle).
  • Add stabilised chlorine to level the pool between 2-4ppm.
  • Allow to settle and recheck chemical levels

8. Shock the pool (if required)

  • Put on PPE and weigh out shock chlorine.
  • Fill bucket with warm water.
  • Add the required shock to the bucket slowly.
  • Stir until dissolved.
  • Add shock slowly to the pool moving around the pool and ensuring not to splash and to pay attention around the skimmer.
  • Ensure all pool equipment is cleaned thoroughly.
  • Leave and allow the shock to do its work.
  • Repeat as needed.
  • Ensure the pool cover is off the pool water until the free chlorine level has returned to 2 – 4 ppm

9. Reinstall the cover

  • When the chemical levels have returned to industry standards, reattach cover to reel and install on pool.

10. Set the pump and filtration timings

  • Check the inlet nozzles are set to provide the best possible circulation.
  • Set the filtration time schedule ensuring enough time to completely circulate the pool.
  • For best heating performance set filtration to turn during the sunlight hours between 11 and 4.

 

11. Check, check and Recheck

  • Recheck pH, FC, CC ,TC and make adjustments if required.

Roth Original Tacker System

Perfectly coordinated system solutions form the basis for handling demanding tasks in the installation of heating. The trouble-free connection of the pipes and the patented laying technique is therefore always the number one choice for all demanding applications. A perfect result is guaranteed, whether it is construction projects of family houses, apartments, offices or industrial buildings.

The demand for high-quality living spaces in both existing and new buildings is increasing all the time,and with it the expectation of state of- the-art temperature control. Whether it be for residential building, office and business construction, industrial and sports halls or open spaces – what was an exception to the rule yesterday has now become expected: usage-optimised heating and cooling systems that continually keep pace with individual requirements. It is therefore hardly surprisingthat the majority of planners and building owners looking for modern and advanced system solutions are now choosing radiant heating and cooling systems. The retrofitting of radiant heating and coolingsystems is also gaining in popularity.

The many innovations introduced by Roth over the years have made a significant contribution to this development. In addition to user comfort and freedom of architectural design, the decisive criteriain the selection of a radiant heating and cooling system are energy savings, hygiene and environmental protection.

An optimal room temperature profile with precisely adjustable dosing makes the performance capability of Roth radiant heating and cooling systems readily perceptible – day in, day out. Equally, negative impacts on room temperature (such as those caused by swirling air, draughts or heat accumulation) are a thing of the past. As a matter of fact, their march of temperature characteristicscorresponds almost precisely to ideal heating (see graph).

Experts know: the larger the heatradiating surface, the more effective and economical the room heating will be. In comparison with conventional radiators, the ideal room temperature with a radiant heating system is 1 ºC to 2 ºC lower. The resulting energy savings of 6 to 12 % speak for themselves, as do the lower system and flow temperatures. These systems are also extremely well suited for use in conjunction with equipmentthat produces renewable energy, such as Roth solar panels. Additional plus points are also to be found from the point of view of hygiene: the dryness of the heat deprives bacteria and dust mites of themoisture they need for survival.

Roth Original Tacker® System… proving its worth in millions of new buildings

Roth Original Tacker® System – for solutions that retain their value A system solution whose components are designed to work together in perfect harmony provides the basis for mastering sophisticated heating construction tasks.

The Roth Original Tacker® System (which has proven its worth a million times over) used in conjunction with Roth DUOPEX S5® and X-PERT S5®+ system pipes provides the ideal foundation for creating a heating supply system that will retain its value in the long term. The friction-free interlocking comprehensive connection of pipe and patented pipe laying technique is therefore always the first choice for the entire array of sophisticated applications. Perfection in the result, whether it is for residential, office or industrial construction projects.Three system steps to perfection The high-quality ex-works prefabrication of all system components – pipe, composite panel and accessories – makes it possible: the complete Roth radiant heating and cooling system is laid in only three work steps using the patented Tacker technique. Of course, everything is in accordance with a precise computer calculation and taking into account all valid regulations.

Roth radiant heating and cooling – comfort can be so simple Fase of assembly with a high degree of flexibility, paired with operational and building site safety and superior efficiency, characterise Roth radiant heating and cooling systems – even with unusual floor plans. The Roth Original Tacker® System makes assembly really simple and enables pipes to be positioned to the centimetre, with a view to achieving optimum heat distribution and cooling, even in the most difficult installation situations.

The underfloor constructions of Roth radiant heating and cooling systems conform to DIN EN 1264 (“Waterbased floor heating”), taking into account DIN 18560 (“Floor screeds in building construction”), DIN 4109 (“Sound insulation in buildings”) and the Energieeinsparverordnung (Energy Savings Regulation [EnEV]). The consistently high quality standards of the individual components and of the overall system are documented by a large number of marks of testing, monitoring and quality. System composite panel for radiant heating and cooling systems Simple, fast, in compliance with standards: system composite panels made of polystyrene particle foam. An excellent choice for heat and sound insulation. They provide a self-enclosed space at the blink of an eye during the pipe laying stage. This makes it possible to have a two-sided, self-adhesive overlap that is 30 mm wide. A secure closure against damp and screed (in accordance with DIN 18560) prevents sound and thermal bridges from forming. In addition, animprinted grid makes it easier to put the system pipes exactly in place in accordance with precisely calculated laying distances. A strong solution for high stresses The Roth EPS 30 SE 26 mm systemcomposite panel comes into play wherever traffic loads are high (in car showrooms, for example).

This composite panel or panel combination can be utilised under an appropriately coordinated screed construction with maximum traffic loads of up to 35 kN/m2. The Roth range of products also includesadditional insulation panels made of EPS or PU, which may be needed depending on the thermal insulation requirements of the application in question
