Using air source heat pump for heating heat source, in terms of safety, cost, service life has obvious advantages, especially in a heat pump system can not only meet the demand of the winter heating, and can satisfy the need of the summer air conditioning refrigeration, and energy use is the most popular electricity floor heating in Europe's new house is very common, but the use of terrestrial heat water temperature is about 30 ℃, but the room temperature can be constant in 20 ℃ or so, due to low water temperature, so the air source heat pump can achieve higher efficiency.

Compared with mainland China, floor heating temperature 45 ℃ or more generally used in water temperature, and even some system water temperature above 60 ℃. And the reason for that,

There are two main reasons:

It is the heat source that does floor heating at the beginning is gas furnace, because of its water quantity limitation, so water temperature nature requirement is higher, cannot achieve ideal heating effect otherwise;

Second, the Chinese people use floor heating and air conditioning habits are the same, some people at home to open floor heating, no one when the time off, if the floor heating water temperature is too low, each time the boot heating time is very long, the effect is not ideal. It can be seen from the comparison that using air source heat pump as heating source has obvious advantages in terms of safety, cost and service life. In particular, a heat pump system can meet both the heating demand in winter and the cooling demand in summer, and energy is the most popular power.

By contrast, the wall hanging furnace is limited by the quantity of air supply and the air supply pipe network. Speaking from the environmental protection, the gas wall-mounted furnace has CO2, SO2 and other emissions, but also consumption can do other USES of high-grade energy. As can be seen from the above analysis, heat pump as an independent heating system heat source, has a huge advantage. Wall-mounted furnace heating and air source heat pump heating have unsolvable problems technically. The emission problem and technical obstacle of gas wall hanging furnace are the hindrance of its further development.
