Current Category Pool heat pumps
Pool heat pumps can be widely installed in any kind of places, swimming pool, sauna, hot water for homes…
-
Economical and high-efficiency
Using water heat pump technology compared with other ordinary hot water equipment (for example, oil, gas, electric and so on), reduces operating costs by 65-80%.
-
Bright design, easy installation and replacement
Unit design separated for main model and water unit model, with water unit indoor, avoiding freezing in winter. It especially suits for cold climate. The unit is remarkable compact, with pump and flow switch inside.
-
Compressors
Compressor brand names are: HITACHI, SANYO or Copeland. Low sound rotary or scroll compressor, low noise fan, high quality pump, making quiet operation.
-
Multi protection
Multi protections to protect from water temperature compressor exhaust pressure, compressor temperature, evaporator temperature and so on.

How to Choose a Pool Heater pump Size
The chart below is an easy way to size a swimming pool heater. Simply determine the surface area square footage and the desired temperature.
Then refer to the chart for the amount of BTUs required to heat up your swimming pool. For example: A 400 sf pool with a temperature of 20 degrees.
The heater output per hour needs to be at least 223,700 BTUs to heat your swimming pool in 24-hours.
