How To Install R290 Heat Pump At Home

For Residential Home Heating And Cooling Scenarios

The R290 heat pump, an air-source model with low GWP, eco-friendliness, and high efficiency, complies with EU regulations phasing out global warming substances but has an A3 flammability rating, requiring cautious home installation. Pre-installation steps include: selecting a well-ventilated, rain-protected location for the main unit; building a 10-15cm cement platform (for outdoor use to prevent water ingress and ensure stability) or cleaning the equipment area; and preparing matching connecting pipes based on the specific heat pump model.

Most manufacturers offer professional installation, but for DIY, key steps are: unpacking with tools (checking for damage and new condition); verifying the heat pump matches the purchased model and normal pressure gauge reading; inspecting internal components and loosening the smart display control panel; connecting the water system (distinguishing inlet/outlet, linking pump/valve/filter); wiring the circuit per the diagram (power lines, sensors, etc.); testing the water system for leaks; and debugging (testing heating/cooling modes, monitoring for abnormal sounds/leaks). Proper installation and regular maintenance reduce leakage risks from its flammable nature.
