| Situated in a newly constructed industrial estate in Papworth Everard, units 10.10 and 10.20 fall under new planning regulations within Cambridgeshire, which state that any new development over 1000m must source 10% of its energy requirement from on-site renewable energy. The site itself is comprised of two large industrial warehouse units and office spaces, with only the office spaces being heated. The owner of the site was looking for the most effective way to achieve the 10% planning requirement and contacted Energy Innovations. The expert engineers at Energy Innovations designed and installed a Gilles 40kW wood pellet boiler, which provides all the space heating for one of the units, and therefore provides far more than 10% of all energy requirements on site. |

| SUITABILITY OF A GILLES SYSTEM
As the units will be let, it was seen as important that the system installed did not put potential tenants off. A fully automated system, allowing a level of control and operation similar to a gas or oil boiler was desirable. The Gilles HPK-RA pellet boilers offer levels of automation such that the boiler can be left to operate unattended for 2 to 3 months at a time. The automatic fuel and primary/secondary air modulation liked to lambda contol and the Gilles advanced combustion control systems allow the boiler to modulate efficiently to match heating and hot water demands through out the year. The boiler is rated over 90% efficient and the level of combustion is such that even at this level of output the ashbin will only need to be emptied 2-3 times per year. THE FUEL STORE A steel fuel hopper, designed to hold around 10 tonnes of pellets has been installed outside the main building. A Gilles pellet auger will feed pellets through to the boiler on demand. Fuel can be either blown into the hopper or loaded from smaller bags. CARBON SAVINGS A conventional gas heating system installed on the site would produce around 21 tonnes of CO per year which will be offset by the pellet system. |
