Hi, I have owned a pool for about a year now that was built back in 1984. Its 12,000 gallons with an attached 810 gallon spa that spills into it. Also it is indoors. My propane heater broke when we first got the house and now were looking at rebuilding our whole pump system and adding a heat pump to it. We want to go electric b/c we are adding solar our house that will hopefully cover most of the cost of heating the pool. If that doesn't fit into our budget then just adding water solar panels to the pool system. I am trying to figure out what is the best setup for our pool and spa as far as how many pumps, one for the spa and one for the pool and what pumps and filters i should be running. Best automated pool cleaner, electric vs suction and if its suction should it be on its own pump? The pump I have now doesn't have enough suction for the pool cleaner to climb the walls. I don't really trust most of our pool people around where we live due to the fact that no one has ever had anything good to say about any of them so i'm trying to gain as much good knowledge as I can before we rebuild. Any advice or recommendations would be greatly appreciated!
