New changes to the government’s non-domestic Renewable Heat Incentive (RHI) will see air-to-water heat pumps finally included in the scheme, as well as a tariff increase for solar thermal technology, and a split tariff increase for ground source heat pumps.
Tariffs as follows:
- Air-to-water heat pumps – 2.5p/kWh
- Solar thermal technology – 9.2p/kWh
- Ground source heat pumps – 8.7p/kWh for the first 1,314 hours of operation and 2.6p/kWh thereafter.
This is a welcome boost for the air source heat pump industry in particular, as the scheme had previously omitted air-to-water heat pump technology, but now recognises the significant role it has to play in delivering a cost-effective and sustainable means of heating commercial buildings.
Other key changes to the scheme include increased support for large biomass heat projects and the inclusion of:
- Deep geothermal heating – 5p/kWh
- Biomass combined heat and power (CHP) – 4.1p/kWh
- Biogas technology – 5.9p/kWh for medium biogas (200kWth and above up to 600kWth)
- 2.2p/kWh for large biomass (600kWth and above)
