Heat Pump Systems

Heat Pump Systems

There are 2 main types of heat pump available.

– Air source heat pumps
– Ground source heat pumps

Air Source Heat Pumps

“Heat your home with energy absorbed from the air around you!”

Air source heat pumps absorb heat from the outside air so it is usually placed
outside at the side or back of a property, and takes heat from the air and boosts
it to a higher temperature using a heat pump. This heat can then be used to heat
radiators, under-floor heating systems, or warm air convectors and hot water in
your home.

The pump needs electricity to run, but the idea is that it uses less electrical
energy than the heat it produces as it capitalises in the heat absorbed from the air.

There are a number of benefits in installing an air source heat pump. These
include:

– They can generate less CO2 than conventional heating systems.
– They can provide heating and hot water.
– They require very little maintenance.
– They can be used for air conditioning in the summer.
– You need to use electricity to power the pump which circulates the liquid in the
outside loop, but for every unit of electricity used by the pump, you get between
two and three units of heat – making this an efficient way to heat a building.

Cheaper Economy 7 electricity tariffs can be used to lower the cost of electricity
to power the heat pump and special heat pump tariffs may be available from
some electricity suppliers – alternatively consider solar photovoltaic panels for a
greener source of electricity.

Will I need Planning permission?
Air source heat pump installations In England and Scotland may be considered
Permitted Development, in which case you will not need planning permission,
but the criteria are complex so it is always a good idea to check with your local
planning office. However in Wales and Northern Ireland they do require planning
permission.

Ground Source heat pumps

“A ground source heat pump system harnesses heat from underground by pumping water through it.”

It uses pipes which are buried in the garden to extract heat from the ground. This heat can then be used to provide home heating i.e radiators, under-floor or warm air heating systems, and hot water in your home.

The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year – even in the middle of winter.

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.

The heat pump performs the same role as a boiler does in a central heating system, but it uses ambient heat from the ground rather than burning fuel to generate heat.

The pump needs electricity to run, but the idea is that it uses less electrical energy than the heat it produces.

There are a number of benefits in installing a ground source heat pump. These include:

– They could lower your fuel bills, especially if you replace conventional electric heating
– They could provide you with an income through the government’s Renewable Heat Incentive (RHI)
– They could lower your home’s carbon emissions
– It doesn’t need fuel deliveries
– It can heat your home and provide hot water
– it requires little maintenance

We work closely in partnership with our preferred suppliers to properly survey and advise on the best, renewable energy system for your situation. This may be an air or ground heat pump, solar PV, or solar thermal or a combination of all of them.

We will explain to you the costs involved but more importantly the excellent returns you can receive through fuel savings and of course the government’s Renewable Heat Incentive!
