What is the most efficient electric boiler? 

Most modern electric boilers are highly efficient at the point of use because almost all the electricity they consume is converted into heat. This means there is usually not a huge difference in basic efficiency between good-quality electric boiler brands.

The most efficient electric boiler for a property is usually the one that is correctly sized and properly controlled. A boiler that is too small may run constantly and struggle to heat the building. A boiler that is too large may cycle on and off too often, which can waste energy and reduce comfort.

A modulating electric boiler, which can adjust its output depending on demand, may perform better than a simple fixed-output model. Good controls are also important, including room thermostats, timers, thermostatic radiator valves, and weather compensation where suitable. For the lowest running costs, the whole heating system matters, including insulation, radiator sizing, water temperature, energy tariff, and hot water usage.
