Description
AstralPool HX120 Gas Spa Heater with ~24 kW Heat Output.
Available in Natural Gas or LPG (Propane).
The AstralPool HX120 (previously the Hurlcon HX120) is Australia’s most popular replacement gas spa heater. Built for reliability and performance, it’s the trusted choice for replacing older spa heaters such as the Hurlcon HX 120 Beige, HX 150, MiniMax, MX125, MX150, HiNRG175, and Raypak Spartan 131. Proudly designed and manufactured in Australia, the HX120 has been proven for over 25 years and remains the benchmark for fast, efficient spa heating.
- Physically in stock at our Carrum Downs (VIC) warehouse – ready same-day.
- We are an Authorised Fluidra Dealer (AstralPool & Zodiac) with real warehouse stock and a walk-in retail store — not a drop-shipper or online-only seller.

- Purchase from a genuine Australian dealer offering warranty compliance, after-sales service, and the largest HX parts range in the country.
Fast, Efficient Heating for Spas, Swimspas, and Small Pools
Gas heating remains the quickest and most dependable way to heat spas. The HX120 delivers up to 25kW of output from about 110 MJ/h gas input. It can raise 1000 L of water by 20°C in about an hour under ideal conditions — perfect for on-demand spa use.
Its copper-nickel finned-tube heat exchanger, electronic ignition, and digital touch controls provide durability and precision. The HX120 installs easily as a drop-in replacement for older Hurlcon HX/WX, Wilton or MiniMax units.
