Air/Ground Source Heating

Many have heard of ground source heat pumps and the high efficiency levels they can offer but few have realised that air source heat pumps can also offer significantly higher levels of efficiency when compared to traditional methods of heating our homes.

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.

The 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 the pump, 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.

Your fridge extracts heat from the box inside (to keep food cold) and rejects it at the back. The air source heat pump works a bit like this but in reverse in that it extracts heat from the outdoor air and upgrades it to heat up your hot water supply.

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

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

Microgeneration can help you access carbon trust loans

Microgeneration is registered to be able to help businesses apply for interest free loans for small or medium-sized enterprises (SMEs) in England and Scotland, or all businesses in Wales* that have been trading for at least 12 months. You could borrow from £5,000 to £200,000. It is unsecured, interest free and repayable over a period of up to 4 years. There are no arrangement fees and applying is straightforward.

Solar Energy

Our solar panels use the power in both direct and diffused sunlight, converting the energy into heat, to produce hot water for the home.

A well-sized solar panel system should provide around 50-70% of the hot water requirements of a home.

Our solar panels are designed to go with existing heating systems that use a cylinder to store hot water. The panels are the perfect partner to our Greenstar regular and system condensing boilers.

The solar panels are available in portrait and landscape versions to suit a variety of roof sizes and shapes.

Under Floor Heating

Underfloor Heating is not new, the principles go back to Roman times. In Europe it is the system of choice and in some countries accounts for 70% of new heating installations.

A radiator system transfers energy into the room largely by convection. This convection results in the floor being the coolest part of the room and leaves a mass of warm air at ceiling level.

It also picks up fine dust from the floor and distributes it into the air and over the furnishings.

This can mean that much of the energy, which had been put into the room, is wasted and not in the area you want it to be.

A UFH system heats mainly by radiation. This is the most natural and comfortable form of heating – just like the sun.

Radiant energy emitted by the floor is partly reflected by each surface and partly absorbed. Where it is absorbed, that surface becomes a secondary emitter.

After a while, all surfaces become secondary emitters. Furnishings themselves radiate energy and the room becomes evenly and uniformly warmed. The energy reaches into every corner of the room – no cold spot, no hot ceilings and no cold feet.

When compared to other forms of heating, the overall effectiveness of a UFH heating system can be seen below.

The heat is concentrated where it is most needed for human comfort and energy efficiency.

Condensing Boilers

Like conventional boilers, a condensing boiler burns fuel to heat the water in a metal heat exchanger.

A condensing boiler uses an extra-large heat exchanger (or sometimes two) to maximize heat transfer from the burner and recover useful heat from the flue gases.

In condensing mode the flue gases give up their ‘latent heat’ and exit the flue in a visible plume of water vapour at 50-60°C – they’re usually 120-180°C in a non-condensing boiler.

At the same time water or ‘condensate’ is produced which must be drained away.
