Ok..I've seen posts about the topic of how it's impractical to try to heat your swimming pool with a hot water heater. I get that. Bowman makes, what appears to be, a great heat exchanger and paired with a home boiler that is used to heat a pool. Here in Alabama, boilers are not practical for home heat. So...would a tank hot water heater in a closed loop scenario coupled with a pool heat exchanger be a viable option to heat an above ground 24-foot round pool?
 
Welcome to TFP.

Depends how many gallons are in your pool and the BTU output of the heater.

Over the years some folks have posted here about hillbilly pool heaters through hot water heaters.

It all depends how much you expect out of such a system.
 
A solar cover will heat your pool to about 90 degrees in the heat of the summer. It's a pain taking it off and on and where to put it while swimming, though. 24ft round pool, if 52 inches tall, is about 13,000 gallons.

You could also look into pool solar panels to run your pool water through.
 

Tankless Water Heater to Heat My Pool

Moved from here. I’m going to hook up tankless water heater to my “smaller” 11000 gallon pool, I’ll update how it goes in a couple months. I'm doing the same thing with my 8,000 gallon pool I'm putting up. I ran my natural gas line outside and bought an $80 3.2 gal/min tankless water heater...

heating pool with Home Depot electric water heater?

Would a regular home water heater from home depot 50gal work to heat my above ground pool about 4000gallon pool? The water heater would be set up just for the pool. I live in south Texas and would like to use the pool year round. winter is not very cold but cold enough to be unpleasant if the...

Anyone using a tankless water heater to heat a pool or spa?

Hi folks, I am new here but have really appreciated the info I have found so far, particularly regarding pool chemistry. Apologize for starting a new thread but couldn't find much via search. I want to air out this idea before I start doing something really silly. I bought a home about 21...

Use tankless natural gas heater to heat the pool?

So anyone tried to use tankless natural gas heater to heat the pool? I have Navien 240-A for domestic hot water, it is rated for 200,000 BTU. So theoretically it can easily raise the water temperature overnight by 8F (when nobody at home is using hot water). What do you think?

Heating pool and spa with household tankless hot water heaters

Hi, I've got an unusual situation. I have an inground pool and hot tub in the basement of my home that I inherited. They were previously heated using regular tanked household water heaters, so I know it's possible. Both have good covers and we're recirculating water, so they didn't need to...

SecoSteve.....I did try solar thermal panels last year. But these are primarily for solar hot water heaters. Putting four in a series did get the output of the water to over 120 degrees, if memory serves me correct, but a half inch line didn't raise the temp all that much. You're evidently referring to the thin panel ones with multiple tubes with the headers on top and bottom. My issue is the temp loss you'll have from after dark until the next morning. That's why I'm really enthused about the concept of a hot water heater and a heat exchanger. Just not sure if the 120 degrees from a hot water heater will be enough compared to a 190 degree boiler that most people use them.
 
Thermal solar should valve off at night unless you desire cooling. This probably requires automation of some kind, or at least a solar controller. There are panels made specifically for pools.
