The Importance of Using a Buffer Tank
The main function of a buffer tank is to reserve enough heat for heating system to make the room temperature more stable and the room environment more comfortable. But in actual installation cases, the user in order to save costs, usually abandon the buffer tank which not only sacrifice the comfort indoor heating environment, but also cause adverse effect to heat pump. 

The Importance of Sufficient Actual Circulating Water Flow 
When heat pumps collect and ascent heat for house heating and domestic hot water, Most of them are using water as the circulating and heat transfer medium. Thus, water deliver the heat from heat pump to the using side.
