Perfect for 2–4 people. The Sanden GAUS-250FQS uses natural CO₂ (R744) refrigerant with a COP of up to 4.5 — saving up to 75% on hot water costs. Ultra-quiet split system with built-in freeze protection to -10°C. Backed by a 6-year heat pump and 15-year pro-rata tank warranty.
The Sanden GAUS-250FQS uses R744 (CO₂) — a 100% natural refrigerant with zero ozone depletion and zero global warming potential — to deliver extraordinary efficiency even in cold weather, when most heat pumps struggle.
With a COP of up to 4.5, the Sanden delivers exceptional efficiency. CO₂ technology performs best in cooler conditions — unlike conventional refrigerants that lose efficiency in cold weather.
R744 (CO₂) has zero global warming potential and zero ozone depletion potential. It’s one of the most environmentally responsible refrigerants available and is future-proofed against regulatory changes.
Built-in freeze protection means reliable hot water in all Australian climates. The system operates from -10°C to +43°C — exceptional cold-weather performance without any supplementary element.
At 37–38 dB, the Sanden heat pump is among the quietest in Australia — quieter than a normal conversation. Install near bedrooms or neighbouring properties with confidence.
Qualifies for federal Small-scale Technology Certificates significantly reducing your upfront cost. We handle all the paperwork and pass the saving directly to you.
The GAUS-250FQS tank is constructed from Australian-made stainless steel for long-lasting corrosion resistance. Backed by a 15-year pro-rata warranty.
The Sanden is a true split system — the heat pump unit and storage tank are installed separately, up to 4 metres apart. This means the noisy pump unit can be placed outside or away from living areas, while the tank goes exactly where you need it.
The Sanden warranty is one of the best in the industry — 6 years on the heat pump unit and 15 years pro-rata on the storage tank, covering you long after most competitors’ warranties have expired.
The Sanden CO₂ heat pump is one of the quietest hot water systems on the market. Measured at 37–38 dB at one metre — quieter than a library or a quiet conversation — it runs day or night without disturbing the household. The CO₂ inverter compressor operates with significantly less mechanical noise than conventional R410A or R32 compressors.
Sanden’s stainless steel tanks use SUS316L — the same marine-grade specification used in food processing and coastal infrastructure. No sacrificial anode is needed: zero corrosion risk, zero tank maintenance. Rated for high-chloride coastal environments across Australia. Backed by a 10-year cylinder warranty.
The Sanden GAUS-250FQS is backed by one of the best warranties in the Australian heat pump market.
15-year pro-rata warranty on the storage tank. WARRANTY CONDITIONS APPLY.
6-year warranty on the heat pump unit. WARRANTY CONDITIONS APPLY.
