Everyone loves a good dip in the pool on a hot summer’s day. However, as it gets colder, swimming in the cooler water becomes less enjoyable for many. Once summer is over, you can either close the pool until the next year or extend its usage.
The latter can be done with a DIY Solar Pool Heater kit and for anyone who wants to extend the usage of their pool, here are 15 ideas of how you can do it at home.
1. DIY Solar Pool Heater for Above Ground Pool
This person explains that his house blocks the sun from reaching his above-ground pool in the evenings. He and his wife always wanted to enjoy the pool after work and found it got too cool, so he decided to put together a DIY Solar Pool Heater using plywood painted black and vinyl irrigation hose.
2. Solar Pool Heater – DIY in under $50

3. Make a Solar Pool Heater with Garden Store items
You don’t have to visit a hardware store to buy special tubing to make this specific DIY Solar Pool Heater. This blogger shows you how to make an inexpensive option using a black garden hose. You can choose to attach it to some wooden pieces to secure it or wind it tightly and use some rope to hold it together.
4. DIY Floating Solar Pool Heater
You can also make multiple floating solar pool heaters. These are made using PVC pipe (straight and elbows), 6mm thick black plastic, black pipe insulation, and duct tape. By adding 4 or 5 of these to a pool, and as the sun warms up the plastic, you will notice your pool heating up as well. Watch the video to learn more about how this idea can also be improved upon.
5. Solar Pool Heater – A Weekend Project
If you’re looking for a weekend project and also want to find a way to heat your pool, here’s a great DIY idea for you. This process is perfect for someone on a budget. Normal heating pumps and gas heaters can cost upwards of $3000 but this one is just a fraction of that price.
This DIY’er explains how he made a large enough heater to accommodate his inground pool that holds 22000 gallons of water.
6. DIY Solar Pool Heater – 3 steps to increase the temperature
This vlogger explains how adding copper wire to his prefabricated pool heaters on the top of his deck helped in increasing his pool temperature by 30 degrees.

7. Using a Child’s Toy and Garbage Bag for DIY Pool Heater
This is a very low budget solution for heating your pool on colder evenings. All you need is hula hoops, garbage bags and pool noodles plus a few other household items like scissors and tape. The important thing to remember is that the garbage bag has to be black. If you use any other color, it will not absorb the sun’s heat and your pool water will remain cold.
8. Using a Double-Glazed Window to make a Solar Pool Heater
This is a little bit harder of a project than some of the other ones that have been highlighted on this list. However, if you are a handyman and like challenging DIY tasks, this is for you. You may even be able to find a use for some old windows that you have lying around in the garage or basement.

If you do not want to invest in a new pool pump, this detailed guide will help you with the products and steps needed to make a working solar pool heater at home.

This is a unique idea for a homemade pool heater. The heat absorbers in this process are a few sheets of fluted metal roofing. A pump is used to direct the water from the pool to the header at the top of what is known as the “collector”. The water runs through the heated tubes and at the base of the collector, it is then channeled back into the pool.
For a total collection area of 4.33ft x 16 ft, the project comes in just under $300; quite inexpensive compared to some projects and prefabricated options that are over $1000.
