Panasonic CO₂ Heat Pump Hot Water System
A Panasonic CO₂ heat pump uses heat from the outside air to heat your water, and it keeps doing that through a Canberra frost. We fit them in homes coming off gas and on old electric storage tanks that have run out of years. If you arrived here looking for a Sanden, this is what we supply now.
HE-UM60CR and HE-UM40CR · Fitted across Canberra · Heat-pump hot water is on the eligible list for the ACT Sustainable Household Scheme
How does the system work
A heat pump moves heat that is already in the outside air into your water, using far less electricity than an element does.
01
The air outside
Outdoor air holds heat well below freezing. A fan draws that air across a coil, and the coil takes the heat out of it. The air costs you nothing.
02
The heat pump
A compressor squeezes CO₂ until the heat it is carrying is hot enough to be useful, and holds the water leaving it at a steady 63 °C. The heat pump is the only part drawing power, and it draws 2.3 kW at most.
03
The tank
The tank fills from the top down, so there is usable hot water in it long before the whole cylinder is up to temperature. Your tank decides how much hot water you have. The heat pump only heats it.
Coming off gas, or off an old electric tank
Two different jobs, and which one you are doing changes the pipework, the switchboard and how long your water is off for on the day.
Replacing a gas hot water system
Your gas service stays connected for anything else that runs on it, and your hot water comes off gas. We check your switchboard and where the old unit sat, because a heat pump needs its own circuit and the tank needs somewhere to stand. If the old one sat in a cupboard, we work out where the tank goes at the visit.
Replacing an old electric storage unit
An electric storage tank heats with an element, so one unit of electricity gives you one unit of heat. A heat pump does the same job on a fifth to a sixth of that, depending on which of the two sizes goes on. Ask for a quote and we'll size it around how many people are at home and when they shower.
Why we choose Panasonic
Six figures from the 6 kW unit, and they are the ones that decide whether a heat pump suits your home. If the 4 kW is the better fit, ask us for its figures when you enquire.
6.11
Coefficient of performance
How much heat you get out for the electricity you put in. An element gives you one for one. The 6 kW unit gives you just over six, tested to AS 5125. The 4 kW gives you five.
5 hours
To a full tank, at 1.2 °C
Panasonic's own measurement. A 315 litre tank taken from 8 °C to 63 °C on a morning of 1.2 °C. That is a Canberra winter morning.
37 dB(A)
Noise
About the level of a quiet room. The unit can run while you and your neighbours are asleep.
−10 °C
Still working at
The bottom of its range. Your hot water is made outdoors, and this unit keeps making it through a Canberra frost without an element cutting in.
59 °C
Water in your tank
The heat pump delivers at 63 °C and stops when the tank reads 59 °C. Your tank holds that overnight, and your shower draws it off in the morning.

Controlling your system. It's easy.
The controller has eight settings, and the daytime window is the one worth asking about. Run the heat pump between 10am and 4pm and your hot water is made on power your roof would otherwise export for very little. Your tank works as a water battery.

- A button. Heats the whole tank now
If you already have solar, PV timer is the better setting. It re-heats your tank on what your roof is making at that moment, so there is no window to set in summer and reset in June. It needs one wire run from your inverter to the controller, and we can do that on the same visit if we install your solar.
If your home has no solar on it yet, one of the overnight windows is the next best answer, and we can price the roof at the same visit.

What the ACT will help you with
Heat-pump hot water is on the eligible list for the ACT Sustainable Household Scheme. The scheme is a loan, and it is arranged before the work starts.
The ACT also runs a separate program for households holding a concession card, the Home Energy Support Program, and heat-pump hot water is on its list. That program pays a rebate. Which one you can use depends on your address and on what you hold, so ask us and we'll tell you which one applies to you. The ACT rebates and loans page sets out the loan terms.
A heat pump also earns federal small-scale technology certificates in its own right. We claim them, and the value comes off what you pay on the day. How many depends on the model and on where your home is, so we work it out on your quote.
The ACT schemes stop at the border. If your home is in Wollongong or anywhere else in NSW, the rebates and loans page is the one to read, and the NSW loan runs on its own terms.
