Designed and manufactured in Australia, the HX120 has been a trusted heater platform for more than two decades, valued for its \u003cstrong\u003erapid heat‑up times, low maintenance requirements, and excellent operating efficiency\u003c\/strong\u003e. \u003c\/p\u003e\n\u003cp\u003eDelivering approximately \u003cstrong\u003e24 kW heat output\u003c\/strong\u003e (around \u003cstrong\u003e110 MJ\/h gas input\u003c\/strong\u003e), the HX120 provides true \u003cstrong\u003eheat‑on‑demand\u003c\/strong\u003e, allowing spas to heat in as little as one hour when correctly sized and pools to reach operating temperature within 24 hours under typical conditions. In cooler climates, the heating performance is comparable to a much larger heat pump, making gas heating the preferred choice where fast recovery is essential. \u003c\/p\u003e\n\u003cp\u003eAt the core of the HX120 is an \u003cstrong\u003eall‑copper finned tube heat exchanger\u003c\/strong\u003e, engineered to accept high water flow rates while delivering \u003cstrong\u003eup to 83% thermal efficiency\u003c\/strong\u003e. The copper design helps reduce scale formation in the waterways, improving heat transfer, reducing servicing frequency, and extending heater life when water chemistry is maintained correctly. \u003c\/p\u003e\n\u003cp\u003eUser control is managed through the \u003cstrong\u003eGenus electronic touch control system\u003c\/strong\u003e, featuring a large LCD interface that displays actual and set temperatures, ignition status, water pressure, and fault diagnostics. \u003cstrong\u003eElectronic ignition\u003c\/strong\u003e eliminates the need for a continuous pilot light, improving gas efficiency and overall safety. Built‑in diagnostic and safety lockout functions assist with servicing and long‑term reliability. \u003c\/p\u003e\n\u003cp\u003eThe HX120 is housed in a \u003cstrong\u003emarine‑grade, powder‑coated steel cabinet\u003c\/strong\u003e, designed to withstand harsh outdoor conditions across Australia and New Zealand. Its \u003cstrong\u003ecompact footprint\u003c\/strong\u003e allows for straightforward installation in confined equipment areas, making it an ideal replacement heater for legacy Hurlcon and AstralPool models. \u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Technical Specifications – HX120\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFuel Type: \u003cstrong\u003eLPG\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHeat Output: \u003cstrong\u003e~24 kW\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eGas Input: \u003cstrong\u003e~110 MJ\/h\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eThermal Efficiency: \u003cstrong\u003eUp to 83%\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHeat Exchanger: \u003cstrong\u003eAll‑copper finned tube\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eControls: \u003cstrong\u003eElectronic touch control with LCD display\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eIgnition: \u003cstrong\u003eElectronic (no pilot light)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eApplication: \u003cstrong\u003eSpas, swim spas, small to medium pools\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBuild: \u003cstrong\u003eMarine‑grade powder‑coated cabinet\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOrigin: \u003cstrong\u003eDesigned \u0026amp; manufactured in Australia\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eModel: \u003cstrong\u003eHX120-LPG\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003eBrochure: \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003ca title=\"Brochure\" href=\"https:\/\/s3-ap-southeast-2.amazonaws.com\/astralpools-au-2\/Products\/Hx_Gas_Heater\/AstralPool_HX_Gas_Heater_Datasheet_Web.pdf\" style=\"color: rgb(43, 0, 255);\"\u003ehttps:\/\/s3-ap-southeast-2.amazonaws.com\/astralpools-au-2\/Products\/Hx_Gas_Heater\/AstralPool_HX_Gas_Heater_Datasheet_Web.pdf\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eManual: \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003ca title=\"Manual\" href=\"https:\/\/s3-ap-southeast-2.amazonaws.com\/astralpools-au\/manuals\/2020_Manuals\/INST_174_HX70_HX120_V08-20.pdf\" style=\"color: rgb(43, 0, 255);\"\u003ehttps:\/\/s3-ap-southeast-2.amazonaws.com\/astralpools-au\/manuals\/2020_Manuals\/INST_174_HX70_HX120_V08-20.pdf\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eGas Heater Sizing guide: \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003ca title=\"Gas Heater Sizing Guide\" href=\"https:\/\/s3-ap-southeast-2.amazonaws.com\/astral-test\/calculators\/Gas_Heater_Calculator-Viron-HiNRG-JX-HX.xlsx\" style=\"color: rgb(43, 0, 255);\"\u003ehttps:\/\/s3-ap-southeast-2.amazonaws.com\/astral-test\/calculators\/Gas_Heater_Calculator-Viron-HiNRG-JX-HX.xlsx\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Astral","offers":[{"title":"Default Title","offer_id":46818004893835,"sku":"AHEA120LPG","price":6000.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/1332\/4427\/files\/Spa-Parts-Pro-Astral-HX-120-Gas-Heater-Natural-Gas-AP-10972-1_1024x1024_5b9e516a-7ecd-4a3b-9026-fc4935fa794f.webp?v=1777252284","url":"https:\/\/www.spapartsonline.com.au\/products\/astral-lpg-water-gas-heater-hx120","provider":"Spapartsonlineau","version":"1.0","type":"link"}
