Heat pump hot water systems

We are proud to offer you our highly efficient hot water systems at a price that is little more than the cheapest comparable electric or gas hot water systems on the market.

Not only will you pay a miserly price for a high quality product, but you’ll slash your electricity bill by around 60%.You can find out more here.

This cost-saving is achieved by the advanced heat pump technology used in our systems, which draws most of the energy to run the hot water system 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.

It means your new system will pay for itself within a few years.

We offer the Midea heat pumps in two sizes. The HP170 litre model is perfect for households ranging from 1-3 people, while the HP280 tackles families of 4-6 or more effortlessly.

How does heat pump technology work?

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.

How does heat pump technology work?

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%.

A highly efficient water heating technology

Cutting edge technology

In addition to using smart heat pump technology, our hot water systems have a whole lot of features which turn a good heat pump into a great one.


Stylish design

The Midea heat pump is a stylish all-in-one unit with slim, elegant lines.

Stylish design

A highly efficient unit

The intelligent heat pump technology as well as the many smart technology features make the Midea heat pumps highly efficient, which means you save money.

A highly efficient unit

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.

Smart control unit

Automatic disinfection function

This feature is brilliant! Once a week theheat pump takes the tank temperature up to 65℃ to prevent the growth of bacteria and Legionella. This means that for the rest of the week you don’t need to keep the tank at 60℃ or more. You can avoid
unnecessary heating costs and tank heat losses by keeping the tank at a much more reasonable 50℃.

Automatic disinfection function

Low operating noise

Rated at just 48 decibels, the Midea is quieter than the average reverse cycle air conditioner. You’ll hardly know it’s there!

Low operating noise

Vacation mode

With a couple of keystrokes you can make sure that when you go on holiday, so does your heat pump, saving you energy while you’re away.

Vacation mode

Tank-wrapped condenser coil

Keeping the condenser coil outside the tank allows efficient heat transfer while avoiding contamination of the water.

Tank-wrapped condenser coil

Wide operating range

The Midea heat pumps operate through a wide range of temperatures.

Wide operating range

Built-in frost protection

No need to worry about the heater being damaged in icy conditions! The automatic frost protection ensures that can never happen.
