This was a typical college way of having a hot tub party. Go to Walmart/Target/Kmart buy cheapest above ground pool, throw a bunch of copper tubing on a grill and circulate the pool water through it.

A BTU (British Thermal Unit) is the measure of energy it takes to raise a pound of water one degree Farenheit.
A gallon of water weighs about 8 pounds. I don’t know how much water an average above-ground pool holds, but I would guess at about 10-20,000 gallons. That’s about 80-160,000 pounds of water!
Now, if you wanted to raise your pool temperature from 75 to 76 degrees for example, that grill would have to be able to put out at least as much power as a 3.5 ton air conditioning unit! (Refrigeration is measured in tons, i.e. 1 ton is 12,000 BTU per hour.)
Like I said, I’m not trying to be nitpicky. I went to school for HVAC, and I’m fascinated by heat exchange and stuff like that. Yes, I am an uber-nerd!
I’m sure this kludge makes a noticeable difference in water temperature though, or they wouldn’t have put together such an elaborate setup! Way to go!
@Paddy
Since you brought it up, this is more of a grill cooler than a pool heater. With roughly 30 gallons per minute blasting through that pipe, about the only thing that’s getting heated up are the bearings on the the pump. He’d be better off tossing the grill into the pool. Or peeing in it (the pool of course, not the grill).
If he is using a copper coil in the grill, and he is recirculating the water (which it kinda looks like he is…) then its not a bad idea at all! Not exactly efficient, but he has the basic makings of an instant water heater.
Ummm….wouldn’t a regular pool heater be less expensive to run? This thing must cost a fortune in propane. Plus being about seven times more dangerous. Although the advantage of being able to make dinner at the same time probably outweighs the downsides.
This one is too clever to make fun of. Congrats, intrepid Rube.
shouldn’t the pump be above water level?
the grill at least….
@Jero
Why? That’s why there’s a pump…
Somewhat ingenious if you ask me.
@Jero
Nah. Those pumps are powerful enough to push water up like 8 to 10 feet.
He could save alot of energy by isolating the block portion of the B&S and recovering the heat from that. Save the barbie for the burgers
A classic case of bouy meets grill.
wow, what a great idea! to bad he didn’t do this in the middle of winter.
dono1, that was incredible.
Also, won’t that give off toxic amounts of carbon monoxide?
Dono, how DO you do it?!
Wow! This one is truly impressive!
Soon to be followed by “Thar she blows [up]!”
I need to start smoking weed, and I’ll make a kickass engineer
This one is as old as the internets. It even has its own website: http://www.redneckpoolheater.com/
Not sure if this is the same one as the one in the photo, but the website is the original one, for sure.
Dono, my hero.

We now return to our regularly-scheduled comments:
“There’s GOT to be a better way to speed up this basting process…”
@dono1
Maybe if they added an old radiator or something…
It is sad, charcoal would add more flavor.
Bravo, sir. Bravo.
The line to shake Dono’s hand starts here.
Paddy, you may be an uber-nerd, but dang it, you’re our uber-nerd. We wouldn’t trade you for anything.
Except a real pool heater.
@Badgirl: Third!
“CHARCOAL!”
“POLO!”
“CHARCOAL!”
“POLO!”
(there’s a joke in there somewhere)
@Badgirl
Aww! *hugs*
@dono1
Heck, I’ll build you a new pool heater!
Little did the photographer know, that grill is the bowl for the worlds biggest water bong.

win!
Bonus points for the terrible-quality cell phone camera that was used to take this picture.
Dono, you’re my hero.

“Gee, Rube, I like your pool party. And the jets in here are nice toasty. But why does the water smell like steak?”

-tAE-
I had something just like this about 7-10 years ago
copper pipe coiled up in the grill part and the water went through it
@jucket
And you’re telling us this because you had HOW many months to live?
I give them points for using a gas-powered drainage pump.
@birddog
That’s actually not too bad an idea. Cool the engine, and recover the exhaust heat. So could you run it rich / lean to control the temp?
oh and on another note it actually worked being heated by the grill as well. thats what happens when boredom sets in lol
Now its a fire hazard and a drowning hazard.
“Ma, my burger tastes like chlorine.”
No one see the little rainbow that goes in opposite direction?
