Swimming Pool Heat Pumps How it works Pool water is drawn through a filter and circulation pump, passed through the heat pump's titanium condenser where it picks up heat harvested from the ambient air, and returned to the pool. Because the temperature lift required is small — typically from 26°C to 28°C — the coefficient of performance is far higher than in domestic hot water duty, making this the most efficient category in the range. Construction and features Titanium tube in PVC shell heat exchanger, chosen because titanium resists the corrosive effect of chlorinated and salt-treated pool water; rifled titanium tubing further improves heat transfer. Copeland or Panasonic scroll compressors, blue-finned evaporator coils, thermostatic or electronic expansion valve, vertical fan discharge. Heating in winter with optional cooling in summer, intelligent defrosting, smart-touch control, optional WiFi control and MODBUS communication for BMS integration. EVI variants available for cold-climate locations. Specifications SE-SP-17U through SE-SP-220V, covering 17 to 220 KW. COP 6.6 to 6.9, maximum output water temperature 45°C.
