Astral JX 160 Gas Heater
Fast heating for pools and spas. The JX 160 is designed to deliver rapid heating performance, allowing most spas to heat in around an hour and properly sized pools to heat within 24 hours or less.
Compact wall-mounted installation. Unlike many traditional gas heaters, the JX 160 is designed for wall mounting, helping save valuable equipment space while making servicing and maintenance easier.
Efficient fan-forced combustion system. The integrated fan-powered draft system improves combustion efficiency while allowing the heater to operate with reduced clearance requirements compared to standard natural draft heaters.
Ideal for tighter installation spaces. Thanks to its compact design and lower clearance requirements, the JX 160 is well suited to confined residential equipment areas and modern pool installations.
Durable stainless steel burner system. The stainless steel Venturi burners are designed for long-lasting, corrosion-resistant performance while producing quieter and more efficient combustion.
On-demand heating convenience. The JX range allows pool owners to heat water quickly when needed rather than maintaining continuous heating, helping reduce unnecessary energy usage.
