£14,848 anticipated annual RHI income for Lincolnshire Biomass District Heating Scheme
In April 2014 Ecoliving installed a wood chip boiler to heat 2 large properties in Kirmington, North Lincolnshire. Kirmington House is a large farm house which was heated by an old Farm 2000 straw burner which, whilst effective, required a significant amount of daily management. Manor Farm is a neighbouring property which was heated by an oil boiler. A heating supply contract was put in place to provide heat on a per kWh basis from the new biomass system, making Kirmington House a Commercial Renewable Energy Producer.
The returns offered through the Renewable Heat Incentive (RHI) scheme made investment in a new biomass boiler for the farm a very attractive proposition. Ecoliving were able to demonstrate a track record of quality biomass boiler installations and experience coupled with referrals from other similar renewable heat installations in the area.
District Heating Scheme Technical Design:
Ecoliving supplied and installed an ETA Hack 130kW wood chip boiler, serving both properties. This includes a wood chip agitator and auger (installed in a silo, constructed from grain silo sheeting) which supplies fuel to the boiler at a regulated rate. Two 1650L buffer tanks store the renewable heat, the distribution system compiles of 64m of Rauvitherm pre-insulated underground pipework between the boiler room and the 2 farm properties and other components such as the flue, the primary district circulation pumps, expansion vessels, flat plate heat exchangers and heat meters make temperature regulation, between the properties, possible.
