We've always joked about getting a pool heater but hubs is seriously thinking about it now. Please tell me where to even start. We have a very simple setup - variable speed pump, sand filter, 1 main drain, 1 skimmer, 2 returns. No spa, SWG, fountains, or anything else. It would have to be a propane heater because we do not have natural gas service in our area and our electric is too expensive for a heat pump type. Pool is about 24,000 gallons. I'm fairly confident Mr. V can do the work himself but I need to start putting together a budget.
