The Dux Airoheat® — 250 litre heat pump water heater
The easy one-piece, compact design makes for a quick and simple installation. Working like a refrigerator but in reverse, it takes air from outside the tank and uses it to heat water.
- Patented in-tank heating coil to improve heat transfer
- Water connections on both sides of the tank for easy installation
- Dual anodes for greater protection against tank corrosion
- Originally supplied with a 5 year tank warranty, 2 year refrigerant components, 1 year full parts and labour

Parts for this system
The Airoheat is discontinued and we do not currently hold parts for it, but we can often source them.
The most common failure on these units is the fan motor — water gets into the bearings, which shows up first as a swirling or metallic noise, then as icing and poor performance. Controller boards, thermostats, ambient air sensors, capacitors and anodes are also available.
Email sales@solarhotwaterparts.com.au with the model and serial number from the data plate and a description of the fault. We will tell you what is available and what it costs — or tell you honestly if the unit is not worth repairing.
