For example, if your swimming pool size is 20m³, if you want to use the swimming pool all year round, the target temperature of the pool water is 28℃, the local minimum ambient temperature and maximum temperature range are 7℃-43℃, and the coldest month water temperature is 10℃. Then your basic requirement is to need an 8.7KW swimming pool heat pump (the selection method is as follows), and then you can buy the most suitable heat pump according to the efficiency of the heat pump and other additional functions of the product.
Swimming pool selection formula (includes pool cover):
Required heating capacity
=Pool size *(target heating temps-coldest month water temps)*1.163/Initial heating time
20m³*(28℃-10℃)1.163/48hours=8.7KW
Note: If there is no swimming pool cover, during the heating process of the unit, there will be 50% heat loss, so you need to choose a heat pump with a heating capacity higher than about 35%. For example, a heat pump of 8.7KW needs to choose a heat pump larger than 10KW.
