Due to outlet water up to 60C, the unit can replace the traditional boilers which are applied to the house heating and domestic
hot water.
Intensive protections have been added to Nulite NEW ENERGY EVI Air to Water Heat Pump in order to make the units run safely.Protections for high discharging temperature, high vacuum degrees excess current and large temperature difference are reinforced in EVI Heat Pump.
