Bio-energy (or biomass) tends to divide a generally pro-renewables audience. Fed by countless images of rainforest destruction, ‘Fuel vs Food’ slogans, and general suspicion of anyone who chops down trees, bio-energy has its fans but its detractors. ‘Do we have enough fuel?&rsqu…

How to choose low energy lightbulbs
Posted by greentomatoenergy . on 20 September 2013 at 9:20 am

Somewhere between 16 and 19 per cent of global power consumed is used for lighting so it makes sense to look at how efficiencies can be made. Traditional lightbulbs, also known as incandescent bulbs (for the purposes of this blog this includes halogens), work by passing electricity through a …

Posted by Cathy Debenham on 16 September 2013 at 9:08 am

Q: I have recently installed an air to heat system in my home. What do I have to do to claim the renewable heat incentive payment? A: First, I'm assuming you are talking about an air to water heat pump. If you have an air-to-air heat pump then you are not eligible for the renewable heat i…

Posted by Tasha Kosviner on 12 September 2013 at 9:58 am

Q: Following the installation of a super-efficient biomass boiler, my energy bills dropped but my energy performance certificate (EPC) rating plummeted 26 points to a G. I’m convinced that the report is incorrect but where do I turn to get this corrected? We removed a 20-year-old boiler…

Can I get the domestic RHI if I'm replacing a renewable heating system?
Posted by Cathy Debenham on 6 September 2013 at 9:43 am

Q: I installed a stove type pellet boiler back in 2006 - which is great. But last year we extended our house and the boiler is probably a bit on the small side. Also as we get older we will find it easier to have a boiler with a bulk store. If I install a bigger output boiler now will I qualify f…

Q: We have had solar PV and solar thermal installed in 2010. While I'm very happy with the solar PV, the solar thermal has never worked particularly well. But as the boiler makes sure there is hot water mornings and evenings when we need it, we haven't really looked into it until now. …
