    Winter Pool Maintenance

    Winter Pool Maintenance: 7 Off Season Pool Care Pro Tips

    Depending on the region you live in, ongoing pool care can be a year round requirement. Yes, the water temperatures are cold, UV ray angles are low and your pool might not have any bather load; however your pump, filter, heater and other pool equipment are functional and need to be watched.

    When it’s finally the warm pool opening season, you don’t want to find out that your pool surfaces and equipment are damaged and unusable. By doing small, weekly pool care tasks, like balancing your water chemistry, you can save yourself from large, time-consuming repairs and replacements. To avoid unexpected problems when it’s time to open your pool for the summer, follow these seven off season pool care tips this winter:

    1. Keep an eye on your pool

    If your pool is covered, remember to periodically remove any debris above the cover and check underneath it to ensure you have no unwanted surprises down there.

    In addition, the winter-induced wind or snow can put stress on your cover, so make sure that your cover, attachments, water bags and lawn anchors are securely attached so they don’t come loose.

    2. Balance your water chemistry

    Water chemistry balancing is not as demanding as it may seem, but it is a crucial part of protecting your pool or spa investment. If pH, alkalinity, cyanuric acid and calcium hardness are out of standard ranges for an extended period of time, it can wreak havoc on your pool equipment and surfacing.

    In the winter, you should balance your pH, pool water weekly at a minimum; spa users are recommended to check their water chemistry every two to three days. In addition, use an algaecide to kill any existing algae and prevent new blooms during the winter. Your sanitizer levels can be reduced during the winter months, while still maintaining the proper water chemistry balance.

    3. Check on your equipment

    Even when your pool is covered and not in use, dirt, pollen and other contaminants can still enter the water. So, remember to keep an eye on the filter gauge, perform backwashing and clean your filter per the manufacturer’s recommendations. Additionally, don’t forget to check your pool pump, heater and exposed plumbing to make sure everything is functioning properly and there are no leaks.

    4. Beware of freezing weather

    If water is left in your equipment during the winter, the cold weather can freeze and expand the water and ruin your equipment and plumbing. So remember keep an eye on your freeze guard to ensure that your pool equipment has circulation when temperatures plummet. This can help you avoid expensive repairs from frozen equipment or plumbing.

    5. Clean your pool surfaces

    Maintaining clean walls, floors and other pool surfaces will prevent algae growth. Skimming, vacuuming and brushing organic debris on a weekly basis is a great off season pool care habit that will save you time dealing with a green, dirty water in the spring.

    Tip: Don’t forget to brush the hard to get areas, including behind ladders, steps and corners.

    6. Clear out unwanted debris

    As debris builds up, remember to empty your skimmer baskets, pump baskets, floor cleaner containers and cleaner bags. This will keep your water and equipment cleaner, while also making your life easier in the spring.

    7. Monitor your water level

    Always make sure your pool’s water level is correctly topped off to protect your pump and keep the pool primed. The right pool water level can depend on the climate you live in. If you live in a warmer environment, that doesn’t experience freezing temperatures, your pool water should almost be filled to the top during the winter. However, if you are located in a cold environment, your pool water should be four to six inches below the skimmer in the winter months. Spending a little time each week on your off season pool care will make a big positive impact on opening your pool this spring and summer.

      Heat Pump

      Heat Pump For Domestic Hot Water

      What is a Heat Pump?

      A heat pump system circulates heat from an external energy source to a compressor inside a heat pump unit. It can collect low-grade heat from renewable sources such as water, ground or air to compress and deliver heating and hot water to a property.

      Advantages

       The actual set of the heat pump is controlled by a climate curve for preventing that the hot air taken from outside (over 25°C with water at 65°C, over 35°C with water at 55°C) may cause high pressure alarms.

      The electrical heater integrates automatically the temperature of the tank to the desired setting when the actual setting is controlled by the weather curve.

      Predisposition for integration with photovoltaic system. After enabling the photovoltaic inverter, the set temperature will increase to the maximum value (according to the climate control).

      Flexibility and Benefits

      Problem with Space? This is the answer. Compact efficient. Solar and 3rd party heating option connections available.

      Waste heat recovery: the unit can be installed near the kitchen, in the boiler-room or the garage, basically in every room which has a largenumber of waste-heat so that it has the higher energy efficiency even with very low outside temperatures during the winter.

      Hot water, cooling and dehumidification: the unit can be placed in the laundry room, in clothing room, gym or garage. When it produces howater it lowers the temperature and dehumidifies the room as well.

      Compatible with solar energy: the unit can work with a second heat source as solar panels, boilers or other different energy sources (remark: the extra heat source is not provided with). The function for which the unit has been designed is only that of heat pump for DHW production. Any other side effect (ambient cooling, dehumidification, waste heat recovery) should be considered as a perk.

      The performance data are therefore provided only with respect to the function of water heating.

      Technical Features

      • Steel tank with double layer vitrification.
      • Anti-corrosion magnesium stick for assuring the durability of the tank.
      • Condenser wrapped externally to the boiler, free from fouling and gaswater contamination.
      • High thickness polyurethane foam (PU) thermal insulation.
      • Outer shell made of grey colour plastic material.
      • Acoustically isolated top part plastic cover.
      • Highly efficient compressor with the R134a refrigerant.
      • High and low gas pressure protections.
      • Electrical heater available in the unit as a back-up (with integrated thermo cut out with protection set at 90°C), assuring constant hot water even in extreme cold winters.
      • ON-OFF contact for starting the unit from an external switch.
      • Weekly disinfection cycle.
      • Possibility of manage hot sanitary water re-circulation or solar water integration (presence of a dedicated temperature probe, flow switch input and command for an external pump).
      • Electronic expansion valve for precise control
      • The pipeline intake/discharge of the air can be reduced from 177 to 160 mm by a reduction / diaphragm (not provided) inserted into the end of the pipeline.

        GROUND SOURCE HEAT PUMPS




        Ground source heating/cooling utilises heat pump technology. A heat pump is a device that moves heat energy from one place to another and from a lower to a higher temperature, or visa versa. Heat pumps are available as both heating only or reverse cycle heating/cooling systems and are classified according to the type of heat source and the heat distribution medium used.

        There are many different variations of ground source energy systems available, but the main types involve utilising the natural thermal conditions of the ground, large bodies of underground water, or large bodies of surface water. Ground source heat pump systems (GSHP) can be used for heating or cooling purposes and obtain their thermal energy from the ground, which has a much more stable temperature profile throughout the year. For heating, the system pump-extract the heat from the underground and distributes it through a pipe system. For cooling, the process works in the opposite way, extracting heat from the building and injecting it into the ground.



        heat pumps



        A GSHP system contains three main components:

        1) The ground side to get heat out of or into the ground.

        2) The heat pump to convert that heat to a suitable temperature level.

        3) The building side transferring the heat or cold into the rooms.



        heat pumps



        The system is a process which allows the transport of heat from a lower temperature level to a higher one, by using external energy. The thermodynamic principle behind a compression heat pump is the fact that a gas becomes warmer when it is compressed into a smaller volume. In a heat pump, a medium with low boiling point (“refrigerant”) is evaporated by the ground heat, the resulting vapour (gas) is compressed (by using external energy, typically electric power) and thus heated, and then the hot gas can supply its heat to the heating system. Still being in the high pressure part, the vapour now condenses again to a liquid after the heat has been transferred. Finally, the fluid enters back into the low-pressure part through an expansion valve, gets very cold and can be evaporated again to continue the cycle.
