The reason for many people choosing air to air heat pumps is their advantage of combining heating and cooling. While compared with the air source heat pumps, the user  experience will have large differences between them.

Cooling is the main function of air to air heat pumps, and heating is only the auxiliary function. If combining these two functions in one unit, air to air heat pumps will cause energy consumption greatly. Otherwise, if the units only have the function of cooling, the COP of them will be much higher. In addition, it is hard for the air to air heat pumps to reach the target efficiency in the cold winter because of the low ambient temperature outside. What’s more, the electric consumption of air to air heat pumps need 300kw each month that will be a big cost for a family, so using the air to air heat pumps for heating is not the best choice.

By contrast, the air source heat pumps have more advantages. Firstly, floor heating gives people great user experience, as the heat comes from floor. Secondly, the heat is even more well-distributed, as it is conveyed by radiation mode. Thirdly, the floor heating pipes will not affect the indoor beauty, because the pipes have been buried underground. Finally, for the energy consumption, the air source heat pumps are more energy saving and environmentally-friendly. It’s the first choice for modern house heating.
