What is heat network efficiency?

  • Updated

Heat loss is an inevitable aspect of the heat generation and distribution process. Understanding the efficiency of the heat network is crucial in gauging its performance.

Higher efficiency translates to lower heat loss. For instance, if a heat network operates at 45% efficiency, it incurs a 55% heat loss. Your heat tariff typically reflects the efficiency of the network; the higher the efficiency, the lower your unit rate.

The overall efficiency of the heat network considers both generation and distribution losses. These are detailed as follows:

Boiler efficiency: Boilers, regardless of type, cannot achieve 100% efficiency, resulting in some heat loss during production. This loss needs to be factored into calculations. Alternative generation technologies, such as heat pumps, biomass, and energy from waste, follow a similar principle.

Heat loss during transmission: Despite insulation efforts, heat loss occurs as it traverses the primary network's pipework.
