Heat pumps are the most efficient form of mains-powered electric water heating, but even after STCs they can be out of reach for many people.
Hydrotherm has a range of lower cost heat pump water heaters using Panasonic rotary compressors to provide a CoP (coefficient of performance) of over 4, so you can reduce your electricity use by over 75% compared to a resistive element hot water system.
There are models available with either 150 or 275 litre tanks. To work out which model you need you can simply use the online system selector by choosing the number of bedrooms and bathrooms your home has and your hot water usage needs.
The systems come with a 2 mm thick 304 grade stainless steel tank with a huge 15-year warranty, with a five-year warranty on the rest of the system. Operating ambient temperature range is -5 °C to 45 °C.
One drawback we can see with these units is that, being a Queensland company, the systems are not available everywhere in Australia. The refrigerant R417a also has a relatively high global warming potential.
The units start at around $995 after STCs are deducted. For more information and to buy, contact Aquatech Solar Technologies Pty Ltd, 94-96 Kortum Drive, Burleigh Heads QLD 4220, ph: 1300 769 904, email@example.com, www.hydrothermhotwatersystems.com.au
