FAQ Pool Heat Pumps


Q: Swimming pool heat pumps - how does a heat pump work?

A: A heat pump works like an air conditioner in reverse. It uses a relatively small amount of electricity to extract heat from the surrounding air and then heats water with this energy.

Q: How much money will a heat pump save me?

A: A swimming pool heat pump with a COP of 5 (efficiency of 500%) will save you 80% of the electricity currently used with a normal electrical element. So, for example, to heat a 50 000L pool with an electrical element could currently cost about R1500/month. If a heat pump with a COP of 5 is connected to this pool and the current electrical element is disconnected then they will not only use R300/month to heat the water.

Q: Do I need a pool blanket?

A: The thermal losses on the surface of a pool is significant and even a slight cool breeze blowing over the surface of the pool can drastically cool down the pool. It is therefore very important to always use a thermal pool blanket to cover the pool when not in use even if it is an indoor swimming pool. If for some reason a thermal pool blanket cannot be used we would normally recommend the heat pump to be 3 times bigger. In other words, due to the losses you will now need to spend 3 times more money on electricity per month.

Q: How long will it take to install a heat pump system?

A: On average it takes less than half a day to install a heat pump system.

Q: How hot can a pool heat pump system make the water?

A: ITS heat pumps are designed for a maximum temperature of 40°C. The heat pump can produce these temperatures even with the ambient temperature being below 0°C.

Q: How much maintenance and service is required?

A: Our heat pump technology requires virtually no maintenance of the system except for making sure the evaporator is clean from dirt and leaves. We do however recommend that the system be checked annually to ensure that you are getting the best possible efficiency out of the system.

Q: What are the advantages of heat pumps over solar collectors?

A: The main advantage of a pool heat pump is that it can heat the water all year round and independent from the weather conditions. The black “spaghetti” pool solar panels that you often see covering the roof of a house is very cost effective and works well if you would just like to extend the usable season of your pool for a few months (and if you do not have a lot of cold wind in the area).

Q: What is the life expectancy of a heat pump system?

A: The life expectancy of a heat pump is more than 10 years.
