Q: How fast can the pool be heated by the heat pump?

The time needed to heat a pool depends on how big the heat pump that you have is, the volume of the pool and the heat loss from the surface of the water in the location you are in. Depending on the month of the year it is, the first time you switch on the heat pump you can expect a temperature rise of between 0.1 and 0.3 degrees per hour. This also depends on the heat pump installed as well. For a quick guide to calculate how many hours it will take to heat the pool is a calculation (pool volume x 4.18 x temperature rise)/ 1800 Then divide the answer by the kW of the heater chosen and that is the approx. number of hours. (Note this is just to heat up the water and doesn't take into consideration the heat loss during heat up and other environmental factors) A heat pump is designed to maintain a pool temperature by running everyday. This ensure the water is always ready to swim in. (Note that a pool heat pump sized for Extended season only will not be able to achieve the set temperature in the winter months)

Q: What is defrosting option in our heat pumps?

Defrosting is a process used to protect the heat pump from frosting when the climate reaches very low temperatures, a reversible valve is installed in any unit that we have by default, this valve reverses the flow of the heated refrigerant at the compressor to flow back to the condenser to keep it from frosting, this is done automatically in case of any frostings started to form on the unit.

Q: What is the coldest temperature at which the heat pump can be operated?

Our heat pumps can be operated in temperatures as low as -10 degrees Celsius and as high as 45 degrees celsius.

Q: How does a pool heat pump work?

Heat pumps are basically a reversed cycle of an air conditioner, refrigerant R32 is the working fluid in our heat pumps, initially the fluid is liquid, refrigerant absorbs energy from the ambient air through the evaporator causing it to evaporate which leaves the R32 in the gas state. After that the gas refrigerant escapes to the compressor in which it’s heat and pressure are raised to the highest in it’s cycle, then it flows to the condenser, which operates as a heat exchanger, the heat of the refrigerant is exchanged with the low temperatures of the water in the pool system, causing the refrigerant to turn into liquid and heating the pool water. Finally, the liquid refrigerant goes back to the initial point which is the evaporator to repeat the cycle again for pool heating.

Q: How do I choose a heat pump?

Our team of experts are ready to guide you through your pool heat pump selection. The size of a heat pump is determined by the pool size, climate, whether you wish to swim through winter or not, and if you plan on using a pool cover.
