How to Heat a Pool Fast DIY: A Beginner’s Guide Updated for 2025
Published January 15, 2025
A warm pool can significantly enhance your swimming experience, whether at home or in a commercial setting. For homeowners, a warm pool means extended hours of enjoyment for the entire family. For commercial pool operators, it’s an opportunity to boost revenue by keeping pools open even in cooler seasons. However, traditional pool heating methods can be both costly and time-consuming.
Pool heaters, while effective, can range from $300 to $5,000 and may take several days to heat an entire pool. Not to mention, they can significantly increase your energy bills. But what if there’s a cost-effective, DIY solution to heat your pool faster? Enter the DIY solar pool heater, a simple and affordable way to keep your pool warm without breaking the bank.
How Does the DIY Solar Heater Work?
A DIY solar pool heater is a budget-friendly alternative to expensive heating systems. It works by using solar energy to warm up your pool water. The setup includes a spiral of tubing exposed to sunlight, which heats the water as it passes through. Here’s how it works step-by-step:
- Water is drawn from the pool using a small pump.
- The water travels through the tubing, which absorbs heat from the sun.
- The warmed water flows back into the pool, gradually raising its temperature.
This ingenious system is easy to build and costs less than $100, making it an ideal project for DIY enthusiasts. Depending on sunlight intensity, the DIY solar heater can raise the pool temperature by 10°F to 20°F in just a few hours.
Materials You’ll Need for a DIY Solar Heater
Creating your own solar pool heater is straightforward and affordable. Here’s what you’ll need:
- 100ft to 200ft Irrigation Tubing | $15
- Irrigation Tubing Connector | $10
- Sump Pump | $10
- Wooden Sheets and Boards | $10
- Optional Tools: Drill, screws, table saw (if not available, rent or find alternatives)
Most of these items are available at local hardware stores or online. Once you have everything, you can start building your DIY solar heater.
Step-by-Step Guide: How to Heat a Pool Fast DIY Style
Follow these steps to create your DIY solar pool heater:
- Build a Base
- Cut the wooden sheets into a square base, approximately 4ft x 4ft.
- Attach wooden boards around the edges to create a shallow frame.
- Drill a hole in the center of the base, large enough to pass the tubing through.
- Prepare the Tubing
- Lay the irrigation tubing in a tight spiral on the base.
- Start from the outer edge and work your way toward the center, leaving the ends accessible.
- Secure the Tubing
- Use zip ties, clamps, or screws to hold the tubing in place. Ensure the spiral is tight and well-secured.
- Connect the System
- Attach one end of the tubing to the sump pump. Use the tubing connector to secure the fit.
- Place the other end of the tubing back into the pool.
- Set Up and Test
- Position the solar heater in a sunny spot near your pool.
- Submerge the sump pump in the pool, plug it in, and turn it on.
- Watch as the water circulates through the tubing and returns to the pool warmer than before.
