Greater Flexibility and Enhanced Efficiency

Using a thermal store allows greater flexibility and enhanced efficiency when applying Ecodan QUHZ to different types of homes. Varying the setpoint of the thermal store, and how much of the store is heated, ensures the correct amount of hot water is produced for the home.

How Does an Ecodan Hot Water Heat Pump System Work?

There are three key components to the Ecodan Hot Water Heat Pump System.

The Outdoor Unit
Just like a heat pump for space heating, the Ecodan outdoor unit uses electricity to absorb freely available heat energy from the surrounding air and then transfers it to your home so it can provide energy efficient hot water heating and heating for underfloor, radiators or fan coils.

The Hot Water Cylinder
Ecodan provides your home with hot water via a dedicated all-in-one pre-plumbed 170, 200 or 300 litre cylinder that is specifically designed to integrate with the Ecodan outdoor unit. Alternatively, the Ecodan outdoor unit can be connected up to a different size hot water cylinder via the Ecodan Hydrobox module.




Smart Energy Controls
Ecodan Hot Water Heat Pump Systems come standard with built-in Smart Energy Control. This easy-to-use interface provides homeowners with smart energy monitoring to maximise energy efficient operation. Furthermore, advanced weather compensation ensures the system delivers comfortable heating no matter the season. The controller is intuitive to use, with individualised room temperature control available at your fingertips for the ultimate in total home comfort.

Energy Efficient Hot Water Heating

The efficiency of a heat pump is known as the Coefficient of Performance or COP. This is a ratio of the heat delivered to power consumed. For every 1kW of electrical input energy, Ecodan absorbs renewable heat energy from the outdoor air to provide the home with over 4kW*2 of heat output.
Compared to typical gas and direct electric heating systems that can have higher running costs with COPs as low as 0.82*3, Ecodan provides an energy efficient alternative.

*2 The overall system efficiency and energy savings will depend on the comparison with your current heating system, satisfactory system design and installation, and operational settings i.e. how you use the heating system.
*3 Based on manufacturer information for gas instant hot water heater (non-condensing).

Combine Hot Water Heating with Whole Home Central Heating

As you have come to expect, Mitsubishi Electric Ecodan Heat Pumps are advanced systems that can do more than just efficiently heat hot water. The extensive line-up also includes total home heating solutions that cover all of your hot water needs as well as super energy efficient room heating – all through the one system.
These total home heating solutions provide room heating using radiators or fan coils as well as underfloor heating. It’s the ultimate in total home comfort.
