Renewable Heat Incentive (RHI) Scheme for Domestic Properties Overview Who is eligible? The Renewable Heat Incentive (RHI) scheme for industry, The domestic RHI scheme applies to both off-grid and business and the public sector was introduced by the on-grid properties in England, Scotland and Wales. Government in November 2011 as part of its commitment to reduce the country’s carbon emissions by 20% by 2020.
Tariffs When discussing the RHI scheme with your customers, the first question you’ll probably be asked is “how much will I get and for how long?” What criteria are required to apply for the scheme? Training All installations must be carried out by an MCS approved Tariffs have been calculated by The Department of Energy installer and meet the relevant standards for each and Climate Change (DECC) and will change annually in-line technology.

Is a heat pump suitable for the property? It is essential that heat pump systems are designed to In existing properties, boilers are often oversized and operate efficiently in order to meet the heating needs of should therefore not be used to determine the actual heat the building, and the expectations of the customer. In order requirements of the house.
Site preparations and guidance Heat pump installations should be made in accordance to Installation clearances the current MIS3005 micro generation installation standards, Min. 1,500mm including MCS020 planning standards. Min. 300mm Min. 1,000mm Siting of the outdoor unit Wall Min. 500mm The heat pump is located outdoors and contains a number of sensitive parts. It is important that it is stood on a flat, solid base, e.g. concrete slabs*.

A minimum of 25mm is required between the unit and other permanent installations e.g. 558 walls, sinks, etc. DHW Expansion vessel Front view Inlet control set Min. 25mm Min.
Installation requirements System design requirements The heating system should be designed to maintain 70% Alternatively, or where TRVs are used a by-pass may be of the nominal flow of the system across the heat pump fitted. This must still maintain 40% of the nominal flow at all times. across the heat pump. Underfloor heating systems should have at least half of the Where it is not possible, due to the design of the heat coils fully open at all times.
The following examples are for demonstration purposes only: Maintenance on the outdoor heat pump The outdoor heat pump unit should be checked regularly An air source heat pump is typically sized to provide around for leaves and debris, especially on the evaporation fins and 85% of the peak load of the house on the coldest day.

Frequently asked questions What benefits do air to water heat pumps offer over ground source heat pumps? There are significant benefits – lower installation costs – no need to dig trenches or boreholes. The Greensource • The air path to and from the unit must be checked to ensure it is clear • The heat pump water drain tray and the pipe to it must be checked to ensure it is clear and clean.
What is the most efficient flow water temperature setting? Is planning permission required for the installation of an The lower the flow water temperature the less hard the air to water heat pump? heat pump has to work and the more efficient it will be. Planning permission varies and is installation specific.
