R290 Air Source Water Heater Replace Gas Fuel Heater with CE/CB Certificate

R32 environmental refrigerant

1. R32 has a GWP of 675, roughly 30% lower than that of R410A
2. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate
3. Ozone Depletion Potential of 0
4. Easier to recycle than R410A, as R32 is a single component refrigerant

Floor preheating and drying

Protect your home floor by activating the Floor Preheating function which slowly increases the heating temperature of the floor coils, avoiding possible floor damaging and transitioning smoothly to the heating function. The Floor Drying Up function provides an additional solution to the installer as it helps remove any residual moisture from newly installed floor coils, further protecting the installation and ensuring the optimal and effective operation of the heat pump.
