Today more and more pools and spas are fully heated using low cost gas heating, extending their usage period and providing you a greater return on your investment. A hot relaxing spa is a delight for the entire family, and is also perfect for entertaining – even at short notice. With an appropriatly sized Astral Pool HX Gas Heater, your spa can be heated in as little as 1 hour and your pool in under 24 hours* making the HX series gas heater a great choice at an affordable price.


Designed and built in Australia. HX heaters incorporate a marine grade powder coated external cabinet which will ensure that it will perform efficiently and last longer in all weather conditions.


The all copper finned tube heat exchanger accepts high flow rates which improves the heater efficiency and prevents scale formation in the waterways. This results in less maintenance needed and up to 83% efficiency meaning you will hardly notice a difference to your current gas bill when heating a 1600L spa.


The large Liquid Crystal Display was designed to be the perfect diagnosis tool providing as much, or as little information as you require. It displays water pressure and thermostat operation, ignition status, actual and set point temperatures. It even helps protect the heater and can be used to run a complete fault analysis if ever necessary.
