不知道电费和gas比如何？
费用差不多的话，就把家里用gas heat的换成heat pump了
实在是没找到有gas heat，带cool，through wall的那种空调 |

When outside temperature is around 40-45F, they become less efficient than
gas heat.

发帖数: 1006 | 8 I think a heat pump means that there is a reverse valve inside the unit.
During summer time, the cold refrigerant flow thru the coil and the fan
blows cold air to the room, then the heat removed from the room will go thru
the condensing coil and will rejected to outside, and the function reverse
during winter (by extract heat from outside and blow them inside).
What you are looking for is not a heat pump anymore, maybe you can write
down the existing one and buy the same model if they still have ti.
