Air vs Ground Source

Both Air Source and Ground Source Heat Pump systems are a very efficient and effective form of heating for customers considering reducing their dependency on fossil fuels and reduce their energy costs, as well as contribute towards a greener environment. They can supply the full heat and hot water demand for a property using a standard wet radiator system.

Payback Scheme

Customers will also receive a payback via the government RHI (Renewable Heat Incentive) Scheme over 7 yrs whilst reducing their energy usage and bills!

Heat Pump Installation

Installation Types

An air source heat pump is usually placed outdoors at the side or back of a property. Ground source heat pumps use pipes that are buried in the garden to extract heat from the ground. Scroll down for more information.

An air source heat pump is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump needs electricity to run, but it will less electrical energy than the heat it produces, giving it a coefficient performance factor usually between 2.5-4.5.

What are GSHPs?

Ground source heat pumps (GSHPs) use pipes that are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home. A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year. The length of the ground loop depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.

ASHP

Takes heat from the air
Better for smaller properties
Less upfront cost
Less efficient
Less RHI payback

GSHP

Takes heat from the ground
Better for larger properties
More upfront cost
More efficient
More RHI payback
