Heating multiple properties or heat loads from a shared biomass boiler or boiler room can be an excellent renewable heating solution, both financially and environmentally.
The number of properties demanding heat and the setup of biomass boilers supplying heat, may range from two small properties sharing heat from a small domestic boiler, to numerous properties (such as a whole farm, estate, apartment block, village or closely arranged group of houses) sharing heat from one large biomass heating plant.
Installing a biomass District Heating System can help to spread the high capital investment across a number of properties. These may be owned by one landlord or business, although it is becoming increasingly common to create biomass networks heating a number of properties under separate ownership, either in a heating co-operative or on a heat purchase basis. Sharing wood fuel production equipment and costs can also help to optimise the efficiency of shared heating systems. District Heating Systems are catered for under the non-domestic RHI and can organically achieve return on investment relatively quickly, providing a fast route for landlords to potential profits from the sale of the heat to end users, or for co-operatives to an economically and environmentally kinder heating solution.
In smaller properties with limited outdoor space, the fuel storage requirements of individual biomass heating systems can be difficult to meet. A District Heating System can enable smaller properties to be linked to and benefit from sustainable bulk renewable heating technology. Fuel delivery or planning constraints and/or aesthetic stumbling blocks can also be overcome when the biomass boiler is situated at a distance from the immediate building to be heated.
