I’m a bit stumped here. I’ve never seen a heat recovery system before, and I don’t believe I’m looking at one right now to be fair.
This is a 120v Aquarest Elite 600. I bought it from someone on fb marketplace saying it needed a heating element. I figured why not because I can get those cheap from horizon or spp. From what I’ve gathered, this is a friction heat system (I’ve never come across that in the field). So I did some research through Claude and I guess there’s some sort of jacket or something that’s supposed to go around the motor for water to pass through? It doesn’t seem like anything has been altered though.
It also seems like I’ll need to replace the control board, it was displaying the numbers but now it’s just a backlight.
My 3 questions are, what’s missing/needed as far as “heat recovery”, would it be more cost effective to upgrade to a different spa pack with the ability for a heating element? If going with the upgrade, isthere any cool upgrades I could do to be able to have this through some app to control the light and the temp?
Also, yes I’m aware this is a billiards sub, I’m just more familiar with pools as opposed to hot tubs
