Hot water heat pumps
Hot water from thin air.
A hot water heat pump heats your water with warmth from the outside air, using a fraction of the power of a standard cylinder.
Up to 77% less energy
Carrier's figure for its Blue heat pump compared with a standard electric cylinder.*
Gas to electric
Swap gas hot water for a heat pump and go all electric.
Made for solar
Use the timer to heat water while your panels are producing.

1 kW in. Over 4 kW of heat out.
A heat pump works like a fridge in reverse. It pulls warmth from the outside air and moves it into your water, so every unit of power it uses gives you several units of heat.
- Runs down to minus 7°C, with a built-in element as backup
- Water heated to 60°C by default, adjustable up to 70°C
- Frost protection and automatic disinfection built in
- Natural R290 refrigerant
Thinking of ditching gas?
Water heating is nearly a quarter of the energy used in an average Kiwi home. Moving it from gas to a heat pump is one of the simplest ways to go all electric, and if hot water is your last gas appliance, the gas bill can go too. We arrange the plumber and gas fitter, so it's one job for you.

Questions, answered.
Does it work in winter?
Yes. The heat pump runs in outdoor temperatures down to minus 7°C, and a built-in element takes over below that, so you still get hot water on the coldest mornings.
Is it noisy?
Not very. Carrier rates its Blue units at 47 to 48 dB(A), about the level of a quiet conversation. We help you choose a spot away from bedrooms.
Can I switch from gas hot water?
Yes. We'll look at your current setup and take care of the changeover, including arranging the plumber and gas fitter. If hot water is your last gas appliance, you may be able to drop the gas connection altogether.
Will it work with solar?
Yes. The controller has a timer, so you can heat your water in the middle of the day when your panels are producing. If you are planning solar, we design both together.
What size do I need?
The common sizes are 190 and 300 litres. We size it to how many people live in your home and how you use hot water.
