Heat loss is a normal part of generating and distributing heat. Measuring the efficiency of a heat network helps us understand how well it is performing.
- Higher efficiency = lower heat loss. For example, a heat network running at 45% efficiency experiences a 55% heat loss.
- Overall efficiency includes both generation and distribution losses.
Efficiency factors
- Boiler efficiency: No boiler can operate at 100%. Some heat is always lost during production. The same principle applies to other technologies such as heat pumps, biomass and energy-from-waste.
- Heat loss in transmission: Even with insulation, some heat is lost as it travels through the primary pipework.
What this means for you
- Some heat loss is unavoidable in any system.
- Higher efficiency means less wasted energy.
