I am in the process of getting my backyard oasis built (pool and spa) and need to make a decision on heat source. I live in Texas and only need the heat source to heat my 7x7 spa. I do not have natural gas so it is either propane tank or heat pump. My pool builder said it might take a full day to get the water temp of the spa up to 104 degrees. Is this true? Is it a no brainer to choose the highest btu rating heat pump? Also, my pool builder said a heat pump is a more cost efficient heat source vs. propane to heat my spa. However, after searching threads on this forum for heat pump I am now scared to go with it. I am also a bit skeptical of using the pump in the heat pump to drive my pool circulation (no heat) vs. having a separate pentair whisper flo. For my needs should I simply go with propane and deal with the pain of refilling it every year?
Thanks.
Thanks.
