My wife saw a way to heat up a pool without an expensive pool heater. She doesn’t want low and slow, she wants hot and continuous. With family flying into town for spring break we’re trying to raise the temp from 65° to 75° today it hit 70. FYI I threw in a little cherry wood so the neighbors at least think I’m cooking something good.

How long did that take? Like 12 hrs? Also home brewer?
This is the fanciest egg I’ve ever seen. What is all the stuff on it? What do they do?
My guess is the heat exchange is relatively efficient. Wouldn’t be hard to measure the outlet temp, you’d want to insulate the outlet pipe until it hits the pool.
Biggest issue I see is flow. You need a higher flow rate.
You’re gonna get in 75* water? Yikes. That’s gonna be cold.
I’d put it vertical and the fire inside the coils. Should work faster that way due to more heat on more surface area. Great idea
Had to push a lot of water really fast I bet. Few thousand gallons an hour?

If anyone wants to nerd out
75? Jeez.. that’s still coldnfor us south Floridians. In summer my 40′ gets up to 93 without the heater. Epic pool parties are had.
The ole wort chiller on the bbq trick!
My dad and I when I was a kid took black hose and created this whole huge radiator that layed out in the yard in the sun. The pool pumped water through it and by time the water ran through all that hose it would come out scalding hot, we could also control the flow. On a sunny day we could litterly heat the pool 10 degrees. Then one summer we build this huge pergola and you guessed it, the whole contraption went on top, out of sight, that’s how we heated the pool for years and years. The cost was minimal, just the T’s and L’s and what ever the black tubing cost
