We've got a heat pump with electric aux heat. It was probably a really nice one when it was installed in 1991. It's still doing a pretty good job of heating and cooling our sieve of an old wooden house with practically no insulation. It does a good job of heating the house down to the mid 40s.

My hypothetical is this, would running water over or spraying the outside coils allow the heat pump to work. The thought just occurred to me when I was outside with the dog. WHen the temp is 36º like it is now, the heat pump has a hard time pulling heat out of the air to pump into the house. If I ran water over the coils, and since the water is well water that's probably ~55º, that water should have enough heat for the coils to grab some.

The other thing that's sticking in my head is that usually water cools things off due to evaporation, and with the fan blowing air over the coils, it seems that could be a detriment.

I'm not actually suggesting that I'd do this, it's a theory question.
