Electric System Boilers

Electric system boilers heat a sealed, pressurised central heating circuit and pair with an unvented cylinder for stored hot water, with no flue, no gas connection and full compatibility with solar PV. Not sure which kW output or phase you need? Use our boiler buying kit builder to size your boiler and match it to the right cylinder and controls.

Choose from single-phase models up to 14.4kW and three-phase outputs from 16kW upwards, from Strom, EHC, Biasi, EHS, Baxi, E.C.A, Elterm and ThermoSphere. A system boiler always needs a separate cylinder: pair it with an indirect unvented cylinder to run radiators and hot water from one unit, which suits family homes with multiple bathrooms.

Need hot water on demand, or replacing a loft-tank system? Browse electric combi boilers or electric heat only boilers.
