The RHI in Practice

Transcript

1. Euroheat Training Academy Small Biomass Conference The RHI in practice Dick Stephens
2. Euroheat Training Academy Small Biomass Conference It’s all about the money, what will we get paid? Two schemes will be running: Domestic RHI - begins Autumn 2013 Commercial RHI - has been paying since November 2011
3. Euroheat Training Academy Small Biomass Conference Domestic RHI tariffs Biomass 5.2-8.7p/kWh GSHP 12.5-17.3p/kWh ASHP 6.9-11.5p/kWh Solar thermal 17.3p/kWh
4. Euroheat Training Academy Small Biomass Conference Domestic 25kW example Payment formula Allowable hours x boiler output x tariff rate 1139 x 25 x £0.08 = £2,278 per year Total over 7 years = £15,946 Include fuel savings of £865 per year = £22,004
5. Euroheat Training Academy Small Biomass Conference Domestic 10kW example Yearly RHI benefit = £911 Fuel saving per year = £346 Total benefit over 7 years = £8,799 under proposed regulations, a 15kW boiler will pay £455 extra/year a total increase of £3,190 over the 7 years
6. Euroheat Training Academy Small Biomass Conference Qualifying Open to all households, with priority given to those off gas grid Some Green deal measure will have to be made Limit of 45kW RHPP payments have to be returned
7. Euroheat Training Academy Small Biomass Conference Commercial RHI Much more generous as it pays for 20 years. Up to 200kW rate is 8.3 p/kWh 200kW-1MW reduces to 5.1p/kWh More running hours 1314
8. Euroheat Training Academy Small Biomass Conference The Euroheat energy cabin can be styled to blend into almost any surrounding area or stand and make a statement of supporting the enviroment. EBEC, Euroheat Biomass Energy Cabin
9. Euroheat Training Academy Small Biomass Conference Client: “So if I buy an energy cabin from you for £89,725. How much RHI payment can I expect?” Answer: “ £20,721 per year, index linked, every year for the next two decades. Take inflation at 2%, that’s a to- tal of £503,484. Add in your fuel savings over 20 years, that’s an additional £175,402. Grand total = £678,887 How many do you want?”
10. Euroheat Training Academy Small Biomass Conference What commercial systems are accredited? Biomass 825 sites 195.0MW GSHP 38 sites 1.0MW Solar Thermal 36 sites 0.5MW
11. Euroheat Training Academy Small Biomass Conference What has been spent so far? Biomass £3.14m GSHP £0.94 Solar Thermal £0.63 Total for all technologies £4.71m
12. Euroheat Training Academy Small Biomass Conference Commercial installations Also includes district heat networks So that includes two domestic dwellings heated by a single boiler Can also include a large house which has an annex with a separate council tax bill OR has an office space within it paying business rates
13. Euroheat Training Academy Small Biomass Conference Biomass the Future Heat metering
14. Euroheat Training Academy Small Biomass Conference Temp sensor (T2) Calculator Temp sensor (T1) Flowmeter Heat source Ultrasonic –no moving parts! Flow Return What is a heat meter? A simple device that measures heat energy
15. Euroheat Training Academy Small Biomass Conference Example Q=mass of water x delta T x specific heat capacity 1m3 per hour = 0.277kg.s-1 delta T = 20 deg C Heat delivered = 0.277 x 20 x4.19 = 23.2kW

18. Euroheat Training Academy Small Biomass Conference RHI meters need to be Class 2 that is +/- 2% accurate Check they have been tested to BS EN 1434 and have either a calibration certificate or a type certificate
19. Euroheat Training Academy Small Biomass Conference Buffering Accumulation
20. Euroheat Training Academy Small Biomass Conference
21. Euroheat Training Academy Small Biomass Conference Paperwork required: Invoice for boiler and installation Boiler warranty and efficiency declaration Heat meter certificate of conformity Independent metering report if site is complex. Commissioning certificate Detailed schematic
