Heat your home with an air source heat pump by extracting heat from outside

What is a Heat Pump?

A short introduction to ground and air source heat pumps

The basic principle is as simple as it is brilliant; taking the free energy that exists in the air and ground outside and converting this energy into heating your home.

This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water throughout your home.

For every 1kW of electricity fed into an Ecodan heat pump unit (outdoor unit) you could achieve at least 3kW of heating energy. An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15°c.

Heat pumps are particularly suitable for rural locations, whether on oil, LPG or direct electric, as huge savings can be obtained.

Is a Heat Pump Suitable for my Home?

To tell if an air source heat pump is right for your property, there are a few key questions to consider

Do you have a location for the heat pump to go?

You will require a position outside your home where an outdoor heat pump unit can be fitted to a wall or placed on the ground. It will need spacing around the heat pump to allow sufficient flow of air. A sunny wall would be an ideal location.

Is your home well insulated?

Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s essential that your home is insulated and draught-proofed well for the heating system to be effective.

What fuel will you be replacing?

The heat pump system will pay for itself much more quickly if it’s replacing an electricity, oil or coal heating system. Heat pumps may not be the best option for homes using mains gas.

What type of heating system will you use?

Air source heat pumps can perform well with both UFH and radiators. But both of these heat emitters need to be properly designed and installed in order for the system to work correctly.

Is the heat pump system intended for a new-build, extension or renovation?

Combining the installation with other building work can reduce the cost of installing the system.

Introducing Ecodan from Mitsubishi Electric

Mitsubishi Electric is a leading global manufacturer of air conditioning, ventilation and renewable solutions

About Ecodan

At the heart of an Ecodan is a modern, inverter-driven heat pump compressor which converts free energy from the air and upgrades it to higher temperatures suitable for heating.

The inverter controls and regulates the system so that heat output modulates to match the exact capacity required – meaning the boiler will only consume the exact energy needed at any given time and thus increase efficiency further.

Heat Pump Maintenance

Achieving the maximum performance from your heat pump system throughout its working life

We believe that by investing in a planned preventative maintenance programme you can ensure that your heat pump equipment operates at its maximum efficiency coupled with optimum reliability and reduced running costs. Relying on a reactive strategy is a short term solution that can prove costly in the long term.

We recommend that your heat pump is serviced annually to ensure you comply with our warranty conditions and also to meet the requirements of the Renewable Heat Incentive (RHI) Scheme should this be of interest.

AES has a range of heat pump service and maintenance packages to support your heat pump system. Whilst it is rare for our customers to experience no heating or hot water we can offer our expertise providing affordable peace of mind.
