I have solar heat but would like to move toward year round use of the pool. I am in Southern California, LA area, where winter is relatively mild. I'd like to have the water temp somewhere between 80 - 85 degrees and I'm trying to find a unit with decent energy efficiency. I have been reading about gas heat versus electric heat pump, but I'm concerned about the heat pump adding to my already high electric bill. SC Edison has penalties for going over the number of therms they say you should be using, so with the need (not want) for A/C during the summer months, lights, computers, etc. gas may be the least expensive way to go. My gas bill is very low, less than 50 dollars monthly, while the electric bill averages 200. Can anyone provide a little more insight? Any particular brands more reliable than others? Features to look for? Best time to buy (is there a typical seasonal sale time)?
Thanks in advance for any help. 8)
