Air Source Heat Pumps Installations

Air source heat pumps are an exceptionally clean and efficient source of producing heating and hot water for domestic properties and commercial sites.

An air source heat pump works by extracting readily available heat in the air and local environment through temperatures between -20ºC and +35ºC, which helps to reduce the dependency on fossil fuels as well as significantly cutting carbon emissions. Air source heat pumps use electricity to operate and run the heat pump. For every 1kW of electricity used, between 3kW and 4kW of thermal energy is available for heating and hot water is available.


How do ASHP's work?

They work much like ground source heat pumps, but instead of extracting the ambient heat from the ground, it is extracted from the air. Unlike ground source systems though, the air around us is affected by the seasonal fluctuations in temperature, which means the efficiency of the system may also fluctuate.

Residential High Temperature Type

Hot water heated to 80℃ is available for domestic hot water and high temperature radiators. Both heating and cooling can operate using heat pump.




Residential Low Temperature Type

Hot water heated to 55℃ is available for floor heating and low temperature radiators. Both heating and cooling can operate using heat pump.

We work closely with air source heat pump manufacturing company daikin to inshore every installation is exactly how they want it, so close they come and sign EVERY single installation off!


So if you're looking for an air source heat pump installer look no further we supply, fit, commission and send off to start your RHI money back incentive.

Choose a professional air source installation company!


Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) is the world’s first long-term financial support programmed for renewable heat.

The RHI pays participants of the scheme that generate and use renewable energy to heat their buildings. By increasing the generation of heat from renewable energy sources (instead of fossil fuels), the RHI helps the UK reduce greenhouse gas emissions and meet targets for reducing the effects of climate change.

There are two parts to the RHI:

  • Domestic RHI – launched 9 April 2014 and open to homeowners, private landlords, social landlords and self-builders
  • Non-domestic RHI – launched in November 2011 to provide payments to industry, businesses and public sector organizations

The RHI is the main scheme of our heat strategy.




Domestic Feed In Tariffs (Price will need to be checked, as changes monthly)



Example – Air Source Heat Pump installed in a typical 4 bedroom house
Total annual Energy demand (taken from the EPC) = 25,000kWh
ASHP seasonal efficiency (SPF) at 4* in Heat emitter guide = SPF 3.0
ASHP tariff= 7.3p kWh
Eligible heat demand = 25000kWh x (1-1/3.0) = 16,666kWh
Total annual RHI payments = 16,666 x 7.3p = £1,216.62
RHI paid over 7 Years = £8,516.33
