Solar pool heating systems use roof-mounted solar collectors to warm your pool water using free energy from the sun. Instead of running a gas heater or electric heat pump, your pool water circulates through solar collectors, warms naturally, and returns to your pool.
This allows you to extend your swim season in the spring and fall while keeping operating costs extremely low.
Solar pool heating is one of the most cost-effective solar technologies available because it directly offsets a major energy expense.
A solar pool heating system connects directly to your existing pool pump and filtration system.
Pool water is pumped through your filter
Water is diverted to solar collectors on the roof
The sun heats the water inside the collectors
Warm water returns to the pool
A controller automatically regulates temperature
The system runs automatically and only circulates water through the collectors when heating is needed.
Extend your swim season by 2–4 months
Very low operating cost
Uses existing pool pump
Automatic temperature control
Minimal maintenance
Long system lifespan
Environmentally friendly
No fuel costs
Quiet operation
Works well in Eastern Washington climate
Heliocol is one of the most trusted solar pool heating systems available. These systems are designed specifically for durability, efficiency, and long life.
Heliocol collectors use individual tube technology instead of flat panels, which allows the system to expand and contract with temperature changes and last significantly longer.
Heliocol systems are known for:
Long lifespan
High efficiency
Freeze resistance
Wind resistance
Low maintenance
Excellent warranty
Solar pool heating systems are very simple systems with very few moving parts. Most systems last 15–20+ years with minimal maintenance.
Typical maintenance includes:
Occasional system inspection
Valve and controller check
Winterization if needed
Pump system maintenance (standard pool maintenance)
Compared to gas heaters or electric heat pumps, solar pool heating systems have significantly lower maintenance and operating costs.
Gas and electric heaters can heat pools quickly but are expensive to operate long-term.
Solar pool heating systems cost more upfront than running a heater occasionally, but over time they are significantly cheaper because they use free energy from the sun.
Most homeowners choose solar pool heating because:
No monthly heating costs
Long system life
Lower lifetime cost
Extend swim season
Environmentally friendly
