Ground Source Heat Pump

Ground Source Heat Pumps utilise pipes that are buried in the ground to extract heat. This can then be used for space heating and domestic hot water.

As the ground stays at a relatively constant temperature under the surface, a ground source heat pump can be used all year round. If the is a greater heat demand is required or space limitations, an alternative to a ground loop is to have a borehole drilled.

Why install one of our ground source heat pumps?

  • Our heat pumps are the first choice for lowering heating bills and reducing your reliance on natural gases.
  • Our heat pumps can reduce your heating costs by a minimum of 40% in comparison to oil and LPG and offer heating, cooling and domestic hot water services.
  • You can also lower your carbon emissions and no longer require a fuel delivery.
  • Planning permission is not required.
  • Our products have a twenty year ‘fit and forget’ lifespan with our online monitoring and inspection tools.
  • With theRenewable Heat Incentive you can also generate a guaranteed income for  period of 7 years for domestic installation and 20 years for non-domestic.

How do Ground Source Heat Pumps work?

Heat from the ground is absorbed by a mixture of water and antifreeze situated within these buried pipes, also known as a ground loop. The length of this loop it determined by the heat requirement. This heat then travels through a heat exchanger, transferring into the heat pump where it is passes through a compressor that raises the temperature, which is then distributed to the heating and hot water systems.

Air Source Heat Pumps

Air source heat pumps absorb heat from the outside air. This heat can be used for a multitude of purposes, from heating radiators and underfloor heating systems, to hot water and warm air convectors in your home.

Some air source heat pumps can be used for heating and cooling. Beneficial for installation within a conservatory, allowing for 365 days a year usage as can heat during the winter and cool during the summer, avoiding the expensive cost of installing blinds or conventional electric storage heaters.

An Air Source Heat Pump is capable of getting heat from the air even when the temperature is as low as -15° C.

Why install one of our air source heat pumps?

  • Lower fuel bills, especially if you are replacing conventional electric heating
  • no fuel deliveries needed
  • can heat your home as well as your water
  • minimal maintenance required

Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods.

How do Air Source Heat Pumps work?

Different from a ground source heat pump, an air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. The heat is absorbed into a fluid mixture of water and antifreeze. This then passes through a compressor which increased the temperature before it is then transferred to your heating and hot water systems.
