Highland Farm Cottages

Commercial Biomass Installation (District Heating Scheme)

Highland Farm Holiday cottages are luxury 5 star self catering accommodation previously with 12 LPG gas boilers, one in each cottage.

Reason for Switching to Biomass

To reduce carbon footprint and save money, estimated £25,000 annual gas bill. Also working towards achieving Gold status as part of Visit Scotland Tourism Award Scheme.

The Solution

Installed in 2014 a Biomass district heating scheme. A fully automatic 150kW biomass boiler now provides heating and hot water for all properties linked from one central boiler with independent control in each cottage.

Boiler, buffer and fuel store located in existing store shed and connected to each building with highly insulated underground pipe. R&I Cruden installed the Biomass boiler and heat interface units in each cottage. Novar estate now deliver wood chip to a custom built 16m3 fuel store. This is a dual fuel boiler that can run on wood pellets or wood chip so not tied down to one fuel source.

The Result

  • Fuel cost saving up to 75%
  • RHI payments for 20 years, CO2 reduced
  • Gold Status achieved
  • Green luxury accommodation.
