My wife would like to add a spa to our backyard. I like the idea but I'm cheap
Anyway a have a decent solar set up, a hard plumbed pool (AG 9 x 18) with a 3/4 HP pump and sand filter. It is automated. My thought was to add a heater after the solar and utilize the existing pump. I can get a "shell" of a spa for free without pump, heater or blower.
I would need another valve/actuator or two, a blower (I guess?) and plumbing.
Would my existing setup be ok? Everything is 120v so I don't have 240 available.
Any advice, pictures, schematics or conversation is welcome.
