Useful upload on YouTube from the Department of Energy & Climate Change that explains the Domestic Renewable Heat Incentive (RHI).
Headline points as follows.
The RHI will pay you a "tariff" per unit of heat generated for the first seven years.
The tariffs are paid per kWh of renewable heat generated based on the following rates (typical annual payouts in brackets):
air source heat pumps 7.3p/kWh (£850)
biomass boilers and biomass pellet stoves with back burner 12.2p/kWh (£2,000)
ground source heat pumps 18.8p/kWh (£850)
water source heat pumps 18.8p/kWh (£850) and
solar thermal (hot water solar panels) 19.2p/kWh (£400)
The above rates will rise annually in line with inflation.
