Astral Pool JX Series Gas Pool and Spa Heater
The AstralPool JX Series gas pool and spa heater is a premium fan forced heater that delivers efficient and reliable heating for pools and spas. Designed for indoor and outdoor applications, the JX offers maximum flexibility and convenience, especially in confined spaces where larger heaters cannot be installed. With its forced draft combustion system, the JX does not rely on natural draught like normal flues. Instead, a fan powers the JX draught, ensuring compact design, superior efficiency and safe operation near windows and surrounding objects.

Key Features of the JX Series
- Premium fan-forced design – Unlike normal flues that rely on natural draught, the JX gas heater uses a fan-powered combustion system. This delivers better efficiency, higher flow rates and cooler operation.
- Wall saving space – Specifically designed for wall mounting, the AstralPool JX gas pool and spa heater is compact and easy to maintain.
- Fast heating on demand – JX heating is immediate, warming most spas in about an hour and, when sized correctly, heating a pool in under 24 hours.
- Durable stainless steel Venturi burners – Designed for long-lasting performance, these burners ensure even flame distribution, quiet operation and resistance to corrosion.
- Indoor and outdoor application – The forced draft combustion system allows safe installation in tight spaces, providing flexibility not possible with heaters that rely on natural draught.
- Efficient operation – As a natural gas pool heater or spa heater, the JX combines compact design with high efficiency to keep heating costs low.
- The JX gas heater incorporates a cupro nickel heat exchanger for improved heat transfer and corrosion resistance.
