From 1st Feb 2012 all new installations of heat pumps need to comply with MIS3005 (Version 3) to get MCS certification. Is the industry prepared for this and indeed can this be delivered?
It seems that many people are not prepared for it and I’m not sure many installers even know this new legislation exists. The legislation involves heat loss calculations for the house in accordance with BSEN12831 and accurate sizing of emitters to ensure high efficiency of the heat pump.
Ground source heat pumps, ground loops etc will need to be precisely sized to avoid freeze up and inefficient running.
Air source heat pumps now need to be sized to cover 99% of the building’s heat load at pre-determined ambient temperatures as described in the CIBSE Guide (A).
Make sure that your heat pump installer is aware of the need for compliance and ask for this in your quote as any non-compliance could cost you your RHI incentives.
There are a lot of implications to this. We could link to the CIBSE Guide?
Feed-in tariffs were effectively halved on 12th December 2011. This has been challenged in court and the Government’s appeal was unsuccessful but they are to appeal again. Anyone who installs a system now could get the 43.3p tariff but if the Government’s subsequent appeal is successful then they will still only be eligible for 21p. Whereas any installation that goes in up to 3rd March 2012 is likely to receive the 43.3p, this is still not guaranteed as Government court action is still pending.
