Solar Swimming Pool Heaters
Frequently Asked Questions
This page answers frequently asked questions about solar swimming pool heaters. These are actual questions asked by interested swimming pool owners and users.
- What is the purpose of solar heating for pools?
- The purpose of any swimming pool heater is to extend the useful swimming season. The modest investment in the solar pool heater guarantees a warm water swimming pool for many years to come. No recurring expenses are needed to buy fuel or to use electricity to warm up the pool water.
- How does a solar pool water heater work?
- The pool water are circulated in a close loop with the help of a pump through a large size solar collectors, get heated up and circulated back to the pool. To view more details click here to read the solar swimming pool heaters operation page
- How are solar swimming pool heaters different than the solar hot water heaters?
- Although the principle of operation is the same and both systems use a solar thermal collector as their main component to heat up the water, there are differences. A solar hot water heater can heat up a relatively smaller volume of water stored in the tank to higher temperature of more than 100 degrees F (37 degrees C). Solar swimming pool heaters circulates the large volume of water that is contained in the pool to relatively lower comfortable temperature at about 78 degrees F (25 degrees C). The solar pool heater doesn’t need a storage tank and the solar pool collectors are much cheaper than the solar thermal panels used for the domestic solar water heater.
- What is the required size of the solar pool collectors?
- As a rule of thumb, solar pool panels with an are equal to 20% of the pool surface area will raise the pool water temperature by 3 degrees Fahrenheit. Five time that, 100% of the area will raise the temperature by 15 degrees Fahrenheit (8 degrees C). If you cover the pool over night you can save on collectors size (size equal money)
- Where can I mount the solar collectors?
- You need an exposed to the sun un-shaded area on your tilted roof facing south. Tilted roofs facing west or east will provide you with a less than optimum performance. If you have a flat roof, use a structure to mount the collectors tilted.
- What are the other components of the solar pool water heater?
- The other components are a small pump, water filters and a temperature sensor (thermostat). In case the water temperature exceeds the comfort temperature, a valve bypass the water and they don’t go through the collectors.
- What would be the expected cost of the solar pool heater?
- The cost depends on the pool size, the region where the pool is in and on how long you want your season to be extended. You can expect a cost of $2,000 to $6,000.
- What do I need to know about maintenance of solar pool heaters?
- The maintenance cost and effort is really minimal. Cleaning the water filters, cleaning the collectors’ surface and taking care of the pump.
