Hot water heat pumps
Hot water heat pumps
A heat pump heats your water with heat taken from the outside air, so it uses about a quarter to a third of the electricity of an electric storage tank. Stiebel Eltron's units can be powered by a 10 A circuit and earn the federal rebate.

How to choose
Three questions decide the model
1
How many people live there?
As a general guide, 200 to 220 litres suits 2 to 4 people. 300 litres suits 4 to 6, or a smaller household with long showers or a big bath.
2
Does the climate matter?
Yes. The SHP-O Premium suits every climate in Australia, from mild coastal cities to alpine areas. Active defrost keeps its heat pump running down to -10°C, so it also handles hard frosts. The SHP-O Plus has no active defrost and works down to -5°C: fine for mild and cool areas, not for regular hard frosts. The same goes for the WWK.
3
Where will it stand?
Outdoors it needs 500 mm clear either side of the air grille. Indoors it needs a room of at least 13 cubic metres. Every model can be powered by a 10 A circuit, connected by an electrician.
FAQ
Questions about hot water heat pumps
How much will I save compared with an electric storage tank?
As a modelled estimate: a household of four using about 200 litres of 60°C water a day needs around 4,400 kWh of heat a year. An electric tank turns that into a bill of about $1,450 at 33 cents per kWh. A heat pump averaging a COP of 3.5 over the year uses about 1,250 kWh, or about $410. That is roughly $1,000 a year less on a general tariff, or about $600 on a cheaper off-peak tariff. Your result depends on your hot water use, your tariff and your climate.
Will it keep working in winter?
Yes. The SHP-O Plus and the WWK keep heating with the heat pump down to -5°C outside, the SHP-O Premium down to -10°C. Below that, the built-in electric element keeps the water hot. Only the Premium has active defrost, so only the Premium suits regular hard frosts.
Can a hot water heat pump heat my house as well?
No. These units heat water for taps and showers only, and Stiebel Eltron warns that warm water returning into the cold inlet would damage them. For floor heating or radiators you need an air-to-water heat pump.
Are they noisy?
Stiebel Eltron publishes 45 dB(A) at 1 metre for the WWK and 47 dB(A) at 2 metres for the SHP-O. Converted to the same distance (sound drops about 6 dB each time the distance doubles), the WWK is the quieter of the two. Either way, put the unit away from bedroom windows.
What does the installation involve?
A licensed plumber connects the water, fits a tempering valve for the bathrooms and any other valves your area needs, and plans a drain for the condensate. An electrician connects the unit to a 10 A circuit: it comes with bare wires, not a plug. Every product page has an installer brief to send them, so you can get a fixed price before you order.
Which rebate can I claim?
Every model earns the federal STC rebate after installation. Some states add more through accredited installers. See rebates by state.
