Biomass Boiler for Lincolnshire Farm District Heating Scheme and Grain Drying

In September 2014 Ecoliving installed a wood chip boiler to heat 7 properties and dry grain at Atterby Farm. A district heating scheme was installed to 7 farm properties using 360m of Rauvitherm pre-insulated underground heat pipe from a central wood chip boiler.

The return on investment offered through the Renewable Heat Incentive (RHI) scheme and fuel savings against oil (for heating) and LPG (for grain drying) made investment in a new biomass district heating scheme a clear cut decision.

Ecoliving were selected on the basis of their demonstrable track record, customer recommendations, and their willingness to deliver what the customer wanted.

District Heating Scheme Technical Design:

An ETA Hack 130kW wood chip boiler was installed by Ecoliving. This biomass heating system includes a wood chip agitator and auger (installed in a block built silo built by the customer), two 1650L buffer tanks for hot water storage, 360m of Rauvitherm pre-insulated underground heat pipework between the boiler room and the 7 farm properties which constitute the district heating scheme. Other components such as the flue, primary district circulation pumps, expansion vessels, flat plate heat exchangers and heat meters were also sourced and installed, to ensure temperature regulation throughout the district heating network. Ecoliving also installed the Dancorn grain drying calorifier (supplied by Peacocks of Brigg) and integrated the humidity controls with the biomass boiler system.
