Higher Efficient
LongClaw series reaches the A+ level(on 20C air condition) which proves its higher efficient heating water and less energy demand,contribution to the energy transition and reducing the carbon.


Sustainable Hot Water
Usually just in a quarter in one day hours the longclaw domestic hot water heat pumps keeps heating the water then storing the water in the tank for whole members usage.
Air Cooling Dehumidifying
When the water heater keep running,the fan keeps blowing the cooling air which is normally around 5degree than the absording air…the cooling air could be directed to the spaces where needs the dehumidification.


Heat Recovery
The heat source which the heat pump demand could be from the outdoor air,but also can be extracted from house indoors like kitchen or toliet room where usually the air temperature and humidity is higher than other places.
LongClaw+Solar PV
Selling the “not-used” electricity from photovaltaic to the national grid? Not advised to do that.Direct them to the heat pump water heater to heat the water to a highest temperature at the soonest time.


Extra Heat Source Availability
In some houses,which already had the solar hot water collectors or boilers or both have, it is a wise idea to intergrate the heat pump with them,to get the hot water from them.
(VR1-120,VR1-100,VR1-80 don’t support this function)
Controlling System:
