AstralPool HX120 Gas Spa Heater – Natural Gas or LPG (Propane)

The AstralPool HX120 (formerly the Hurlcon HX120) is Australia’s most trusted and best-selling gas spa heater. Designed and manufactured in Australia, this heater combines reliability, speed, and long service life in a compact design that’s remained proven for over 25 years.

It directly replaces older Hurlcon HX120 in beige, HX150, HX 150, and all earlier HX and WX gas spa heater models. It also replaces older MiniMax, MX125, MX150, HiNRG175, Raypak Spartan 131, and Raypak Premium 109, 127, 167 units — making it the go-to upgrade option for legacy systems.

About the Hurlcon / AstralPool HX120

Gas heating remains the fastest and most reliable way to heat spas and small plunge pools. The HX120 delivers up to 25 kW of heating power with a gas input of ~110 MJ/h, achieving up to 83% thermal efficiency. It can raise 1,000 L of water by 20 °C in about 1 hour under ideal conditions.

The unit features a copper-nickel finned-tube heat exchanger, electronic ignition, and touch controls for precise temperature management. The compact cabinet and side plumbing layout allow a drop-in replacement for older Hurlcon HX/WX or Purex MiniMax heaters — no major re-plumbing required.
