Haier heat pump hot water systems
The Haier heat pumps are surprisingly high quality heat pumps, with good insulation, features such as an inbuilt timer, and WiFi monitoring via a phone app. They have a generous 5 years parts and labour warranty on the tank and compressor, and an additional 2 years replacement only warranty on the tank.
Although heat pumps generally entail higher upfront costs, the ongoing running costs are very small. Compared to traditional electric hot water systems, they use at least 60% less electricity. And if you have rooftop solar and run the heat pump during the day (which is what you should do), your running costs will be negligible. In many cases this gets you to a happy scenario where the heat pump will pay for itself over a number of years. This payback period is typically around 5 years if you are a medium to large household replacing a traditional electric hot water system. You can find out more here.
This cost-saving is achieved by the advanced heat pump technology used in Haier heat pumps. Most of the energy to run the hot water system is drawn from the surrounding air. Electricity-based renewable hot water systems are the way of the future, and they are rapidly slashing the cost of household water heating.

The Haier heat pumps have very low running costs
The heat pump technology results in a 69-79% reduction in electricity used to heat the same volume of water compared to an electric-resistance water heater.
Low GWP Refrigerant
Our Heat Pump Water Heater uses R290 which has a global warming potential (GWP) of 3. Many heat pumps use R134A. R290 has a global warming potential that is 476 times lower than R134A. As many refrigerants are strong greenhouse gases, the use of refrigerants with low GWP is seen as a way to minimise the effect of refrigeration systems on global warming.
Several size options
We offer the Haier heat pumps in three sizes, which we cover next.
Haier 330 Litre Heat Pump
The 330 litre model is perfect for large households of around 5-6 people with heavy hot water needs. It is quite a large unit as you can see from the dimensions below.

Small and Medium Haier Heat Pumps: 200 and 250 litres
Haier also provides a 250 litre model, which is suitable for families of 3-4 people, while the 200 litre model works well with smaller households of 1-3 people. Details of the size of the two models are shown below.


How does heat pump technology work?
First of all the sun warms the surrounding air. Then a fan draws the air into the heat pump, and across a unit known as an evaporator.
Inside the evaporator is a refrigerant which boils at – 26℃, so this happens even in the depths of winter. The warmth from the air causes the refrigerant to boil and evaporate.
Having turned into a gas, the refrigerant moves to a unit which compresses and further heats it up. Now the refrigerant passes around the outside of the water tank, transferring the heat to the water.
The refrigerant condenses to a liquid state again, and moves back up to the evaporator and the cycle goes round again.
A highly efficient water heating technology
Heat pump technology operates on an entirely different principle to a standard electric hot water system.
With an electric hot water system, a heating element boils the water. It’s no more sophisticated than an electric jug, and it’s not very efficient. For every kWh of electricity that goes into the electric water heater, the most you can ever generate is 1 kWh of heat energy.
In a heat pump, electricity isn’t used to heat the water, but to run the heat pump components, such as the fan and the compressor. Only a small amount of electricity is needed (around 0.4 kWh).
The heat pump draws in the surrounding air, captures the warmth from the air (and there’s plenty of that, even in winter) and uses it to heat the water.
Just 1 kWh of electricity to drive the heat pump can produce around 4 kWh of heat energy when the air temperature is 20℃ or more.
The takeaway message here is that under most conditions, you will slash your hot water electricity bill by at least 60%.

Smart control unit
This unit enables you to change the tank temperature, switch it off when you go on holidays, and set it to operate at the warmest time of the day. And if you have a rooftop solar system, you let it power your heat pump.
