Communal Biomass Heating - Combie Court

West Highland Housing Association commissioned Ecoliving to retrofit a pellet-fuelled Biomass Communal Heating Scheme throughout their social housing at Combie Court, Oban town centre – 24 one or two bedroom dwellings off the gas network. Domestic heating and hot water was previously delivered via electric storage heaters and immersion heaters. These proved to be difficult to regulate and very expensive for tenants, due to rising energy costs. The project was completed as part of WHHA’s wider plan to renovate housing stocks to help reduce carbon emissions in line with Government national targets.

Installation of Biomass Communal Heating Network

Ecoliving alongside sub-contractors, McGougans, installed two 60kW Hertz wood-pellet boilers, feeding a Communal Heating Scheme throughout all 24 flats. The two centralised biomass boilers feed two hot water storage cylinders in an external containerised boiler room, backed up by a smaller LPG boiler for periods of high demand. The storage cylinders feed hot water into each home through an individual Heat Interface Unit (HIU), supplying a wet radiator central heating system, easily regulated using Thermostatic Radiator Valves (TRVs).

Biomass Boiler Performance

To date, the system is receiving more than 98% of its energy from the biomass source, with an average efficiency of almost 90%. The biomass boilers are fully utilised for 42% of the year, demonstrating effective storage capabilities within the cylinders and conservative fuel requirements. 

Communal Renewable Heating Funding

Due to the variety and number of positive impacts as a result of this development, several funding streams were secured for the capital cost of £390,000.
