Readers' tips of the month - December

"Cut energy first by improved insulation, air tightness and appliance energy efficiency, then install renewables," is the tip from chartered building services engineer, Gary Bennett. "You will spend less overall to acheive a better end result," he adds.
He practices what he preaches: "favouring a 'fabric first' and energy reduction approach, over the last 3 years I have implemented a series of low cost energy efficiency measures to our 1980s home and have reduced our heating energy use by 60% and our electricity consumption by 50%".
He installed biomass (pellet - bagged) and solar thermal in 2009. The solar thermal has been successful but the biomass boiler was a Gerkros - and the company went bust 2 weeks after it was commissioned!
The biomass boiler blew its ECU in spring 2013, so he has now converted to oil firing, but has a Hitachi ASHP (air source heat pump) waiting in the wings pending installation of buffer vessel and reconfiguration of heating.
Solar thermal is also the renewable of choice for Woodcotrob, an ambulance service paramedic who lives in a typical 70s bungalow that is "desperately in need of updating/future proofing".
"Having been a solar thermal heating installer back in the 70s, I know how efficient and effective these systems can be. So on buying this place I immediately installed a 30 tube system which I am extremely happy with.
"Two years ago I had a 4kW solar electric system fitted and again this is proving very beneficial. I am still on oil for my heating! I have a modern condensing boiler but wish I could afford a ground source heat pump!"
