Air to water Heat pumps


Air Source Heat Pumps work using similar technology as the ground source heat pumps, but using the outside air as its energy source. In the UK and Ireland, the outside air temperature rarely goes below -3°C. The heat or energy moves from hot to cold (2nd law of thermodynamics) and the refrigerant in the heat pump boils at very low temperatures of -30°C so the difference between the outside air and refrigerant create the energy that flows into the heat pump.



Domestic customers receive a £2500 grant up front, plus they receive annual RHI payments at 5.6 pence per unit (kWhr) for seven years.

The RHI payment for a domestic biomass boiler is typically between £1000 and £2000 per annum. This equates to an impressive average grant income of £13,000 at the end of the 7 year period.

Biomass Boilers

The cost of Biomass fuel is considerably less volatile than oil or gas, and unlike these dwindling fossil fuels, woodpellets are a renewable energy with a secure supply Our Biomass boilers operate up to 93% efficiency and can massively out-perform oil or gas (a typical non-condensing fossil boiler may only be 70% efficient). So your biomass boiler delivers much more heat for every pound you spend on fuel Under the Government’s NI Renewable Heat Incentive (NI RHI) scheme, you will receive regular grant payments when you install a biomass boiler generating renewable heat


Non-domestic customer (0kw -199kw)

Non-domestic customers do not receive an upfront capital grant, but they do receive quarterly RHI grant payments for a 20-year period. RHI is paid at 6.4 pence per unit of heat (kWhr).

The unit costs of oil versus wood pellets will fluctuate, but the RHI payment exceeds both. So in real terms, non-domestic customers benefit from FREE heat plus they get a significant financial reward over the 20-year period.

Linton Solutions offer a wide range of renewable solutions and specialises in the installation of Solar PV County Antrim and Solar PV Northern Ireland wide. Solar PV panels capture light energy from the sun and convert it into DC electricity, the same form of electricity found in a car battery. This DC electricity then passes through an inverter to produce AC. The resulting AC supply is used as the primary source of electricity and can be seamlessly supplemented by the grid, if required.


Grants are there to assist with the purchase of your solar install, you will receive 12p per kW generated from you solar install for 20 years. This is from the Renewable Obligation Certificates or otherwise known as ROCS. As well as generating an income through ROCS whatever excess energy not being used on your property can be sold back to the grid at a price of 5p per kW.

Payback period can be worked out easily from the size of solar install you have purchased by taking into account the following

  • ROC Payments (12p per KW)
  • Electric saved
  • Export – Sold back to the grid at 5.1pence depending on provider
