Nova Power delivered the installation of a low carbon solution to a working farm in Oxfordshire with residential properties on either side of a country lane. They wanted to reduce their heating bills, so moving from oil to biomass was the obvious solution as the estate has extensive woodland from which to self-supply all their own woodchip.

 

The 140kW biomass boiler system, with additional 4000 litre buffer tank, was installed in an existing shed that was undergoing a refurbishment, allowing a purpose built wood chip hopper and plant room to be included in the design. The underground pipe network transferred the heat to the two residences, the farm workshop, a greenhouse and swimming pool.

 

The existing oil boilers in the properties were retained as backup with switches installed to enable them to simply be switched over if needed.

 

Careful controls mean that although the heat for the swimming pool is not eligible for RHI payments, the system as a whole was able to be accredited as a small non-domestic installation under the RHI scheme, guaranteeing payments over the next 20 years.

 

The estate have now felled a number of trees under their existing woodland management scheme and these are drying out, ready to provide effectively free heat to the Estate once they have achieve the correct moisture content.
