The NorthFlo Arc Curved Solar Pool Heater is a practical, energy-saving way to warm your pool using the power of the sun. Designed specifically for above-ground pools, this solar heater helps extend your swimming season without increasing electricity or gas costs.

Its curved profile is engineered to absorb sunlight more effectively throughout the day, allowing water to warm efficiently while maintaining strong water flow. Unlike flat solar panels that rely on direct sun angles, the Arc’s shape captures heat from morning through evening, making it a smart choice for Canadian backyards.

With proper sunlight and circulation, a single unit can raise pool water temperature by up to 5°F (approximately 3°C) over several days. For larger pools or faster heating, multiple Arc heaters can be connected together to increase total heat output.

Key Features & Benefits

• Designed for above-ground pools up to 30 ft

• Suitable for smaller inground pools as well

• Uses solar energy only — no operating costs

• Curved design improves heat absorption and reduces flow restriction

• Simple installation with common pool hose sizes

• Modular system allows multiple units to be linked

Recommended Pool Size

• One heater: Pools up to 12,000 gallons

• Larger pools may require multiple units for optimal performance

Compatibility & Installation

• Fits 1.25" to 1.5" (32–38 mm) flexible pool hoses

• Includes:

  • Flexible hose

  • Stainless steel hose clamps

  • Adapter for Intex 2.25" (40 mm) hoses

Important:
Ultra Frame pools with 2.25" connections require an additional Intex 40 mm replacement hose for installation.

For best heating results, covering your pool at night or when not in use is strongly recommended to minimize heat loss.

For Best Results: Use a Bypass Kit

For optimal performance, installing the NorthFlo Arc Solar Pool Heater with a bypass kit is strongly recommended. A bypass allows you to control how much water flows through the solar heater, helping maximize heat gain while maintaining proper circulation through your filtration system.

Using a bypass kit also makes it easier to:

• Adjust water flow based on sunlight conditions

• Improve overall heating efficiency

• Reduce unnecessary strain on the pump

• Isolate the solar heater for maintenance or winterization

In Canadian climates, a bypass kit provides added flexibility during cooler mornings, variable weather, or shoulder-season swimming when precise flow control can make a noticeable difference.
