Alternative Heat - Technical Insights
- 1. Alternative Heat Renewable Heat Incentive – Our Experience 20th June 2013
- 2. About Alternative Heat • Established 2002 • Installed over 100 biomass boilers to date – equates to over 10MW of installed capacity • 5MW of this in Ireland – estimated carbon saved per annum 6000t • Example customers – Magherafelt Council, Enniskillen Hotel, New Forge Lodge (Moira), Tory Bush Holiday Cottages, Lisnasharragh Police station
- 3. Renewable Products Offered • Biomass Boilers – wood pellet & wood chip • Full Containerised “plug & play” biomass heating solution • Solar Panels • Ground Source Heat • Air Source Heat Pumps • Under Floor Heating *The Complete Package*
- 4. Why RHI? • Current Heat Demand in N.I approx. 17.4TWh • Currently only 1.7% from renewable technologies • N.I. target 10% from renewable heat by 2020 • Significant government intervention required • Reduce dependency on fossil fuel • Reduce fuel poverty
- 5. 2013 Tariffs

- 7. Alt Heat Experience • Submitted over 35 RHI applications to date • Studied legislation and guidelines set out for RHI • Design heating systems in line with OFGEM guidelines • Fit Class 2 Heat meters • Provide calibration cert and confirmation of CE approval • Never fit heat meters on suction side of pump
- 8. Alt Heat Experience Cont’d • Check heat meter compatibility & install as per manufacturers requirements • Provide independent heat meter report for complex systems • Provide clearly defined, site specific, as installed, M&E drawings • Record fuel consumption for submitting quarterly claims *submitting the correct information first time speeds up the application process*
- 9. Different Technologies & Applications • Biomass boilers – Suitable for new build and retrofit applications. High and low temperature heat demands i.e. UFH – Radiators • Ground/Air Source Heat pumps – Suitable mainly for new build highly insulated low temperature heat demands (UFH) • Solar Thermal – Suitable for new build and retrofit applications for hot water and heat
- 10. About Biomass Boilers • Fully automated systems • Highly sophisticated technology • Can run on wood chip or wood pellet • Widely used throughout Europe–over 20 yrs • Increasing in popularity in Ireland & U.K. • More expensive than fossil fuel systems but savings can be significant
- 11. Cost Effective Applications Steady Heat Demand • Hotels – especially with swimming pool • Nursing Homes • Leisure Centres • Hospitals • Industrial – large heat & steam users • Housing – district heating • Agriculture - poultry houses, mushroom growers
- 12. Herz Biomass Boilers • Manufactured in Austria • Established 1896 • 1,500 employees in more than 70 countries • 8 Production sites • Automatic feeding system, ignition, ash extraction, self cleaning, remote monitoring • Boiler range 10kW – 1000kW
- 13. Best Practice • Size biomass boiler to satisfy base load heat demand – more cost effective • Integrate suitably sized buffer tank • Utilise oil/gas as back up to assist under peak load demand
- 14. Containerised – “Plug & Play” Solution 20kW – 1MW • Reduced construction works & time spent at site • Easier to finance • Contains boiler house, boiler, fuel store, feed system, buffer tank & flue • Designed & rendered to customer specifications
- 15. Containerised – “Plug & Play” Solution 20kW – 1MW 6 Awards – best product!!
