How to Build a Solar Pool Heater For an Inground Pool

by Pool Builders on 11-16-2008 in Articles

Are you trying to extend your swimming season or prepare for a better one next year? If so, there are many options when it comes to pool heaters and one of the most economical is a solar pool heater that you can build yourself. Here is a quick plan to help you get started with your new heater.

The most expensive part of this heater is going to be the pump and it will probably have to be replaced every other year. This needs to be strong enough to get the water out of your pool and through many feet of tubing. You can get some advice from your local hardware contractor manager since you will be getting your tubing there as well.

You will need to purchase about 50 feet of black tubing that is between 1/4 of an inch in diameter and 3/4 of an inch and diameter. Anything in between here should work just fine. You will also need some PVC pipe that fits in both ends of this tubing. Probably about 10 to 15 feet will be enough. You should also get a shut off valve that will attach to the pvc pipe.

Now you need to run the pvc from the pool to the pump, then out of the pump and into the black tubing. At the other end of the black tubing you want to run the PVC with the shut off valve back into the pool.

You will be taking the black tubing and running it back and forth between two 2 by 4 pieces of wood that you drill out holes in for the tubing. This should make a 3 to 5 foot set of tubing going up and down the 2 by 4s. This is your heater and you need to mount this part on a roof top or somewhere that it will get a lot of sunlight.

This type of solar pool heater will do a great job at getting you from the 70s up into the mid 80s for most of the year and should help you extend your swimming season by a few weeks or months depending on your climate.
