Moor Heating Stephen Larkin The experience of having the first pellet boiler
Reasons for choosing a pellet boiler. Running cost calculation The installation Pellet delivery Living with a biomass boiler – the first two weeks.
Reasons for choosing a pellet boiler LPG boiler more than 20 years old and becoming unreliable. Stopped working December 2012 Stopped working December 2012 LPG expensive Costs likely to rise Not easy to track use Aim to reduce CO 2 output Change to sustainable energy Pellets more convenient and efficient than other biomass efficient than other biomass systems systems
