Hello,
I have this crazy idea to heat my pool water with a wood stove, but I need a little help with the design.
I would use a small/medium wood stove with a heat exchanger in/on the stove, use a second pump to pull the water from the pool and push it through the heat exchanger, then the heated water goes back in the pool.
Yes it would take a while to heat all the water but I am talking about raising the temp a max of 20 degrees, probably 10 - I dont see why it would not work. Any problems so far?
I need help with the heat exchanger.
What metals would be bad for pool/pool water?
I was thinking about using a copper coil (flexible line - no solder joints) inside the stove, or galvanized pipe loop(s) built with nipples and 90s or the best would be a stainless steel tank/exchanger but that would be a little harder to make up...Maybe aluminum tank also, would aluminum work?...
So again what metals should I stay away from or does it not matter at all?
Not like I would be running it for the whole season.
The fire in the stove would not be crazy hot or big and with the cold water in the line/exchanger would keep it all from melting if it was any where close to the melting point of the metal.
I already have a stove and a pump - just need a loop/tank to give it a try.
Let me know.
thanks Kevin
