Air Source Heat Pumps

How does it work?

The Ecodan air source heat pump system consists of an external box which is fitted to your outside wall.  It harvests renewable, low grade energy from the outdoor air and upgrades this into useful heat to supply a home with hot water and heating. 

For every 1kW of electricity fed into Ecodan, you will get at least 3kW of heating energy.

The outdoor unit is a bit like your fridge in that it has a circuit of factory-sealed copper piping containing ozone-friendly refrigerant, which is continually compressed and expanded to extract the free, renewable energy from the air.

It can work efficiently all year round even if the outdoor temperature should drop to -15ºC.

The ECODAN RANGE of air source heat pump systems have been developed by Mitsubishi Electric specifically for the UK and bring advanced, inverter-driven technology refined in the commercial heating sector to your home.

A variety of styles and sizes for every home.

Ecodan heat pumps are ideal for use in a variety of house sizes or styles and it's carefully developed control system is designed to work perfectly to provide hot water to either traditional radiators or under floor heating systems.

The Ecodan will vary the flow temperature in the room automatically, based on the ambient temperature to keep the house warm.

Operating at these lower flow temperatures significantly improve efficiency (in comparison to older heating systems).

And more good news...

Ecodan offers hope for hard-pressed households everywhere, with a system to suit almost any property, providing they are well insulated; whether it is a small flat or a large detached house. Older properties that have been thermally upgraded can also benefit from this low carbon alternative to traditional domestic hot water systems.

To tell if a ground source heat pump is right for you, there are a few key questions to consider:

	Do you have the space?
	You'll need a place outside your house where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air.
	Is your home well insulated?
	Air source heat pumps produce less heat than traditional boilers, so it's essential that your home is insulated and draught proofed for the heating system to be effective.
	What fuel will you be replacing?
	If you're replacing an electric, oil, Liquid Petroleum Gas (LPG) or coal heating system, an air source heating system will pay for itself more quickly than a new more efficient one.
	What type of heating system do you want?
	Underfloor heating systems or warm air heating will be much more efficient than radiator-based systems.
	Is the system for a new development?
	Combining the installation with other building work can significantly reduce the cost of installing the system.

Costs and savings

Savings can be considerable.

Air source heat pumps are much easier to install than ground source so they are more suitable for a wide variety of properties from flats to detached houses

Advantages of ECODAN
	Lower CO2 Emissions* *In independent tests carried out by the Building Research Establishment, BRE, Ecodan was found to reduce emissions by 50% and running costs by 30% in comparison to a modern gas boiler.
	Reduced energy bills compared to gas. Mean that the system can pay for itself within 2 - 3 years. In areas off the gas network, Ecodan can offer significant reductions in installation and running costs over oil.
	Maintenance on an Ecodan system is easier than gas. And with a professionally maintained Ecodan heat pump unit offering an average lifespan of 15 - 20 years, you'll save on annual maintenance costs too.
