I was over at my brother in-laws Sunday evening for dinner. He has owned his house for about a year now. The previous owner removed the pool furnace, but it's a little cold for my brothers liking so he would like to add a heater. He was telling about a conversation he had with his neighbor where he claimed to have a heat pump to cool the house that in addition also heated the pool. His house gets very warm in the summer, so he would like to add some a/c. I did a little searching and I was not able to find anything like that. Is anyone familar with these?
