Rheem's Commercial War to Water (W2W) Heat Pump Plus range is designed for large commercial hot water systems with both indoor and outdoor installation.
A truly commercial grade heat pump that delivers hot water up to 65°C with a heating system Coefficient of Performance (COP) up to 5.07 at 20°C Cold Water temperature, increasing up to 7.01 at 35°C Condenser water temperature.
Detailed engineering has tuned the system operation allowing the heat pump to operate in low Cold Water temperature, reducing the reliance on auxiliary heating methods, thereby improving overall annual efficiency.
All models are made to order with 10-12 weeks lead time.
Optional Condenser: For longevity in harsh domestic water conditions, a suitable Copper Tube in Tube condenser heat exchanger is available.
