How to choose a good heat pump?

1.Compressor. The compressor is the core component of the air source heat pump. The compressor with poor quality will effect the heat pump lifetime directly.So, when you are selecting the heat pump, you should notice the compressor. All the wotech heat pumps are adopted the imported brand compressor(Panasonic compressor for domestic heat pump, Copeland for commercial heat pump.)
2.Water tank. The water tank decides the safe, keep warm performance and the lifetime of the heat pump.So when you are selecting the heat pump, you should notice the inner material and quality.  
3. Thermal insulation. Heat pump is a storage water heater. When the water temperature reach the set point, it will stop heating, when it lower the set point,it will start heating again. So if the thermal insulation of the water tank is poor, it will cost a lot of energy. Wotech heat pumps are adopted the 500mm thickness polyurethane foam layer, which is with the advanced high pressure foaming technology to once moding. Every 24 hours just decline 4℃, which is more energy saving.
4.Evaporator.The evaporator quality is related to the heat pump efficiency. The evaporator tempereture is required to be lower than the air temperature,then it could absorbing the heat from the air.So the evaporator will easily has the condensate water. If the condensate water on the fins could not drain then it will easily attched the dust and become the dirt. In winter it will frozen and effect the heat exchange. Wotech heat pumps are adopted the hydrophilic concave-convex fins,which make the evaporator absorbing heat more quickly and higher efficiency.
