District heating is an intelligent way of heating two or more buildings from the same system. By doing this commercially, you are able to receive a higher Renewable Heat Incentive (RHI) from the government, turning the energy you make into an income.
A district heating system comprises a network of insulated pipes used to deliver heat in the form of hot water or steam from the point of generation to an end user.
A heat network enables valuable energy, which is all too often wasted in power generation or industrial processes, to be harnessed and delivered to a point of use. This removes the need for additional energy to be generated. It also allows for economies of scale as the generation of heat in one large plant can often be more efficient than production in multiple smaller ones.
