Deemed Heat Calculation and MCS/RHI for Solar Thermal

[LeakyNick]

Hi

Anyone out there understand how the heat calculations for the 18p/kWh works for 'deemed' heat input for Solar Thermal and the Renewable Heat Incentive? Does it only require the SAP 2009 calculation Appendix H which looks compare the solar tube efficiency against the dedicated amount of water to be heated by the cylinder? Or is another method used, say a full building load assessment and an estimate of water heating requirement?

Thanks

Its still not finalised as far as I can find out

Right thanks. I'm curious because it seems to me that solar-thermal is independent of the heat-load of the house. Also, if you use the Appendix H SAP calculation, they don't seem to give a good value for calculated kWh from the panels where I know from experience, my panels are giving way in excess of what it calculated and if the under-valued figure is used, I'm not sure the RHI is actually worth it!!!!

Right...and they seem to be playing their cards close to their chest then!
