Ground Source Heat Pumps

Green Build Energy work with carefully selected Ground source heat pump manufactures to provide our Domestic and Commercial customers with high quality products and installations. Ground Source Heat Pumps use pipes buried in the ground to extract heat. This is usually used to warm water for radiators or under floor heating systems. It can also be used to pre-heat water before it goes into a more conventional boiler.

Ground source heat pump can be used throughout the year - even in the middle of winter due to the ground staying at a constant temperature. This means that Ground Source Heat Pumps provide one of the most efficient ways of heating and cooling properties using renewable energy.

Air Source Heat Pumps

Green Build Energy supplies and installs Air Source Heat Pumps, again we have dedicated time and effort to pick the best from a growing market place, providing our customers efficient high quality design and installations. Air Source Heat Pumps reuse thermal energy by collecting it from the air. Air Source Het Pumps can be used for central heating, hot water and cooling. The efficiency of an Air Source Heat Pump depends quite strongly on the outdoor temperature. The advantage compared to ground source heat pumps is that no ground work is required. The downside is the lower efficiency in cold weather.

They are normally cheaper then Ground Source Heat Pumps so may more easily be installed when budgets are tight.

Heat your home with energy absorbed from the air around you
Air source heat pumps absorb heat from the outside air. This heat can then be used to warm water for radiators or underfloor heating systems, or to warm the air in your home.

How do air source heat pumps work?
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 extract heat from the air even when the outside temperature is as low as minus 15° C.

The efficiency of air source heat pump systems is measured by a coefficient of performance (CoP) - the amount of heat they produce compared to the amount of electricity needed to run them. A typical CoP for an air source heat pump is around 3.3 at an outside temperature of 6 degrees, the Cop will increase with higher outside temperatures.



The benefits of air source heat pumps

Reduce your fuel bills: air source heat pumps run on electricity, so there's no need to pay for gas, oil or solid fuels to heat your home.
Cut down on wasted electricity: heating your home with an air source heat pump is much more efficient than using electric radiators.
Save space: an air source heat pump system is compact, and requires no storage space for fuel.


Is an air source heat pump suitable for my home?
To tell if an air source heat pump is right for you, there are a few key questions to consider:

Do you have somewhere to put it? 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? Since air source heat pumps produce less heat 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 system will pay for itself much more quickly if it's replacing an electricity, Liquid Petroleum Gas (LPG) or coal heating system than a gas or oil one.
What type of heating system do you want? Air source heat pumps can be used to heat a radiator system but are better suited for powering underfloor heating systems.
Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.


Costs and savings
Costs for installing a typical system suitable for a detached home range from about £5,000 to £9,000 including installation. Running costs for space heating and hot water for washing are likely to be around £790 per year. This will vary depending on a number of factors - including the size of your home and how well insulated it is.

Savings can be considerable - up to 5 tonnes of CO2 and £700 per year for a system that replaces an electric heating system.
