Hot Water Heat Pumps

The WWK 222/302 (H) hot water heat pumps have an active defrost function that switches on when the frost monitor detects a build-up of hoar frost at the evaporator. When frost is detected, it will switch the fan off but will keep the compressor running. Hot vapor is directed to the evaporator and the condenser is shut off, this hot gas will begin to actively defrost the evaporator.

Yes, the H-models, WWK 222 H and WWK 302 H, are heat pumps with smart elements. These models have a 1.7 kW element that when engaged will heat approximately the top 80 litres of the tank.

The heat pumps have an active defrost function that can control any icing that occurs at lower air temperatures. The active defrost function will remove any hoar frost that occurs at the evaporator and then reverts back to hot water generation mode.

Our heat pumps have an encased compressor design to reduce noise. They are operating at 46 dB. Heat pumps do make a sound when they are operating which is the sound of the compressor and fan. The noise from a heat pump is dependent on a number of factors, we encourage our customers to read the operating and installation guide to also take into account the positioning of the heat pump when installing.
