What does a biomass boiler annual service involve?

Posted by Trish O'Flynn on 7 December 2016 at 12:30 pm

What does a biomass boiler annual service involve?

Biomass boilers that burn wood logs, chips or pellets, require more attention than gas or oil boilers when it comes to filling, cleaning and fuel delivery. They should also be cleaned and serviced regularly as build-ups of ash and clinker can stop the boiler working efficiently. Some of these tas…

Self-driving cars could save energy

In 2014 transport accounted for 38% of the UK’s final energy consumption [1]. The majority of this was due to the use of road vehicles, both for private transport and for business. Cars account for a considerable fraction of the greenhouse gasses we emit. As roads get more congested the…

Heat Pumps: Air source or ground source?

Heat pumps are devices that use a small amount of energy to move heat from one place to another. During cold weather they extract heat from outside sources and pump it indoors. This process can be reversed during summer in order to act as an air conditioning system. The heat pump circulates a…
