District Heating Schemes

A District Heating Scheme (DHS) is a term used for a boiler which is heating more than one property. It is the simplest way for many people to be eligible for the non-domestic RHI, and can be a cost-effective way of installing a biomass boiler system.

DHSs are especially popular with farmers or estate owners who own 1 or more tenanted properties which they can heat along with their own / main house.
The different properties are connected to the boiler room via insulated underground pipe, the ‘District Main’. We then provide a heat transfer enclosure at each property (which consists of a heat meter, heat exchanger, balancing valves, and any other property-specific requirements) through which the heat from the district main is transferred to the property’s hot water and heating systems.  

We have installed various DHS under the non-domestic RHI, which have ranged in size from 2 -11 different properties, including a scheme which is heating one entire side of a small rural village encompassing 0.75 km of underground pipework. 

If you would be interested in finding out more about district heating schemes, please contact us for more information. We would also be happy to arrange for you to visit an existing scheme.
