Are you tired of paying a fortune in utility bills to enjoy your swimming pool for an additional couple of weeks? A lot of homeowners have to make this sacrifice every year.
If you would like to have a chance to prolong your swimming season while significantly reducing your energy costs, then you should consider installing a solar swimming pool heater. The following article will take you through the entire process and explain each step in detail.
Understanding How A Solar Swimming Pool Heater Works
A solar pool system utilizes solar thermal energy. Water from the pool is circulated through solar collectors and heated.
The system includes collectors, a filter, a pump, a flow control valve, and a controller. The controller senses temperature differences and allows the flow of water only when heat is available.
There are two types of solar collectors: unglazed and glazed. Unglazed collectors are made of durable rubber or plastic and are best suited for warm weather. Glass and copper tubing are used to make glazed collectors, which are more efficient in a cooler climate.
The size is the most critical factor when choosing solar collectors. It is recommended that the area of solar collectors should be 50-100 percent of the pool’s surface area. This depends on the pool’s location, the roof’s orientation, shading, and the temperature desired.
Professional Consultation And Sizing Process
Every installation starts with a site evaluation. The technician inspects your pool’s water volume and surface area and the condition of your pump and filter.
A technician then checks the solar resource by examining the roof pitch, azimuth, and shade. South-facing, unshaded roofs are optimal.
They talk about usage and target temperature and season length. They use it to determine how much BTUs are needed, the circulation rate, and how many collectors are required.
The next step is permits. Most cities require a building and plumbing permit for roof-mounted solar thermal in 2026. Some HOAs may also require special approval. A professional solar thermal contractor can take off the permits.
What To Expect When Installing a Solar Pool Heater On Your Property
Roof And Ground Mount Preparation
On install day, crews show up with mounts, collectors, pipes, and safety equipment. For roof installations, they’ll find spots on the rafters to mount your flashed mounts and seal all penetrations.
For ground installations, crews will secure a level rack at the appropriate tilt (usually your latitude) and make sure that the installation is safe and up to code.
Be prepared to hear some drilling sounds and maybe have your water shut off for a little while. It usually takes 4-8 hours to mount an array.
Plumbing Integration And Controls
Once mounted, the installers will run insulated lines to your equipment pad, where a check valve, vacuum breaker, and a bypass for drain-down and freeze protection will be installed.
The solar loop is connected to the filter and is placed before any chemical feeders to ensure that the collectors are protected from freezing and that the water is heated efficiently.
The controller is wired in, and temperature sensors are mounted on the collectors and near the pool’s plumbing to allow for automated flow control and prevent overheating.
System Testing And Homeowner Handover
Pros will pressure test the loop, check for leaks, and ensure proper flow rate. They’ll check the controller differential, valves, and the pressure pumps under full sun.
They also run the system through at least one heating cycle to ensure that it can raise the temperature by 5-15 degrees over a couple of sunny days.
Finally, they give you operation and maintenance instructions and provide warranty information. You’ll learn how to check the pressure and winterize the system.
Why Choose A Certified Professional?
Licensed installers will properly size the system, make it code compliant, and keep the warranty intact. They will also take care of structural reinforcements, sealed penetrations, and flow balancing.
They’re also good at getting maximum power out of the wind, indirect, and cloudy days. Flat plate systems are good at using diffuse radiation, which means they can produce power throughout the day.
For the best results, SolarTubs provides SRCC certified high efficiency systems with a 20-year warranty and pre-engineered packages to make installation easy for professionals.
Going with the experts can help you avoid leaks, code violations, and warranty issues while making sure that all the permits are properly documented and approved.
To Conclude
Professional installation can make sunlight pay off in warm water with little effort and big savings. From permitting to mounting, plumbing to testing, every step is done right.
If you’re shopping for options for the next season, you can’t go wrong with experts installing a solar pool heater because it ensures proper sizing and a neat setup. A reliable company such as SolarTubs provides a quality solution that will prolong the swimming season for decades while helping you reduce your carbon footprint.
Frequently Asked Questions
How Long Does Professional Installation Take?
Most residential systems are installed within one to two days. Permits and inspections can take two to six weeks.
How Many Collectors Do I Need?
Allow 50 to 100 percent of the surface area of your pool. Less if you live in a warm climate; more if you live in a cooler climate. A solar cover reduces the amount of solar collector area required.
Do Solar Pool Heaters Work On Cloudy Days?
Yes, but they aren’t nearly as efficient. Solar collectors that are glazed are better than unglazed ones on cloudy days.
