My 140 feet copper coils with manifolds from the original Redneck Pool Heater
Cajun style burners (KAB5) from http://www.cajun-outdoor-cooking.com/Kick_A_Banjo_Burner.htm
I bought 2 and each puts out 210,000 BTUs with the 30psi upgrade (not needed as I found out later...to much HEAT)
These are the standard 20psi hoses that come with the burners. Just right. 30psi upgrade not needed.
Side view of heat assembly
Start of the 4 sided cover box made from tread plate and angle iron
Four tread plate sides are ready. I used scrap so I had to tack weld small bits to make larger plates.
One side with angle iron legs is being checked here
Three sides of cover box is clamped to welding cart and ready for final welds
The cover box is almost ready 30“ x 14.5” x 16“ with 24.5” lags
Handles make placing the box over the burners and coils easy
Tread plate fire box rests over heat assembly with no attachments. Just a wind block.
Bottom of fire box is open but the top will be covered with these adjustable ventilation covers.
Ventilation covers from Home Depot (not needed once you know how much air flow is required) I recommend simple fixed vents
Two 16“ x 16” brick pavers from Home Depot for a base.
Brick pavers nicely leveled beside pool deck.
burners set on first
Coils rest on top of burners.
Fire box sets over burners and coils.
Cover rests on top with room to spare.
Top is on but I later find its best that the vents are only 10% open for best heat transfer and flame.
Rapping the heated hose around the low part of tank keeps tanks running until they are empy, else they freeze up and stop at 1/4 tank.
One tank lasts 3 hours with upgrade 30psi hose (upgrade hose not recommended, standard 20psi hose would have been fine...to much heat anyway)

My output was going direclty from 80F to 119F with just one trip through the heat. Later I got 80F to 121F by closing the vents to 10% open.
