I bought a 16' x 4' pool, but found that a gas or electric heater would cost more than the price of the pool itself. I also had a lot of limbs and split wood from a fallen tree in my yard. This made for a very easy and effective combination. Now, when I burn wood in my fire pit, I also heat my pool.
Step 1: How it works
Step 2: Materials
- One old, but useful, fire pit or grill
- 60 foot coil of 3/8 copper tubing
- 10 feet 1/2 water hose
- plastic 1/2 female water hose adapter (recommended) and zip tie
- 6+ feet black foam pipe insulator
- 1/2 hose clamp (comes with female hose adapter above)
- 4 wire copper pipe hangers
- 1000 gph Submersible sump pump with water hose adapter
- scrap brick or stone
Step 3: Installing the copper tubing
I would recommend feeding at least 2 feet of tube through one hole for the intake and 10 feet for the outtake. Drill small holes for the u-shaped wire pipe hangers and install, bending to fit the bulk of the coil. The coil cost about $75. A little costly, but it is much more efficient and easy to install than using a series of elbows and straight pipe, as in my original design.
