- 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.
- What happens when the heat pump reaches the desired swimming temperature?
Heat pumps have built in thermostats that monitor the pool's temperature, when the swimming temperature is reached the heat pump is turned off automatically, it comes back in operation only if the pool temperature is dropped by 1 degrees less than the set temperature. All our heat pumps have the best of inverter technology which allows it to drop to a lower speed and higher efficiency. You may notice a reduction of the fan speed once the heat pump displays the set temperature this is how it maintains a perfect swimming temperature whilst your filtration pump is running.
our heat pumps can be operated in temperatures as low as -10 degrees Celsius.
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.
The time needed to heat a pool relies on how big the heat pump that you have, the bigger unit the faster heating, Moreover, in all of our selections we always choose heat pumps that will reach the desired temperatures in less than 10 hours in the coldest day of the year.
With regular maintenance and servicing, our heat pumps can last a lifetime with no issues.
All our heat pumps come with the highest quality titanium finned heat exchangers, allowing you to use any type of water without worrying about the units lifetime.
Having a pool cover will significantly reduce the size of the heat pump required for your pool, thus reduce the unit cost, that is due to its ability to save the heat supplied to the pool from being lost to the atmosphere.

Yes that is possible however, this will not reduce the size of the heat pump and that is because solar heating cannot be operated in certain climate conditions for instance if the weather is cloudy only the pool heat pump will be operating thus you need it’s full capacity to work.
