Electric heating: comparing systems fairly
Electric heating covers different technologies. A resistance heater, such as an electric panel or convector, converts electricity into heat. A heat pump also transfers heat from a source. Do not compare these principles by input wattage or purchase price alone; the same heating demand is the starting point for a fair choice.
Comparing with gas requires actual heat demand and the existing system’s efficiency. One fixed conversion from gas volume to electricity demand does not suit every system. Output is measured in kW and consumption in kWh. For resistance heating, consumption follows power multiplied by actual operating time. Assess heat-pump performance under relevant conditions.
Include insulation, controls, electrics, any floor changes, maintenance and domestic hot water in the plan. Solar generation does not always coincide with heat demand; consider winter use and your tariffs too. Low purchase cost, free heat or automatic payback cannot be substantiated for every home. Phased supplementary heating may require a different choice from full replacement.
We help private and business end users, installers and wholesalers compare options and products. Share a floor plan, insulation, existing installation and intended use for an informed proposal.
