Variable Applications
Heating capacity range from 3.5kW to 7.5kW, the heat pump
delivers 75 to 160 liters per hour hot water to hot water storage
tank as individual system, also it works together with electric geyser
and solar water heater as backup and combined system, in order
to obtain best efficiency.

System Operating Process
1. Tap water goes into water tank;
2. Water pumped to heat pump;
3. Water heated in heat pump and
pumped back to water tank for
storage, and repeat process 1-3;
4. Hot water 55°C ready for use;
Note: Water tank need to be ordered separatedly.
