The Electric Heating Company recognise that “Time is Money” and as such developed Electric Boiler & Cylinder Heat Packs that incorporate all the necessary components (with the exception of radiators, radiator valves and pipe-work) for a complete Electric Heating & Hot Water system.

EHC offer Electric Boiler & Cylinder Packages to reduce installation time by up to 70% by offering Pre-Plumbed Indirect Cylinders with their range of Comet PV Electric System Boilers. The Pre-Plumbed Stainless Steel Unvented Cylinders incorporate pre-wired controls, automatic by-pass, wiring centre, combination valve, temperature and pressure relief valve, tundish, 2 x 2 port valves, filling loop and high efficiency circulating pump which is included within the Boiler. They are designed with the busy installer in mind as all plumbing and electrical connections are prepared for an instant fit.

For properties requiring large amounts of Domestic Hot Water an Indirect Cylinder will re-heat quicker than a Direct Cylinder with a 3kW Immersion Heater.

Comet PV Electric Boiler Packages are available with single phase Boilers from 8kW to 14.4kW with a choice of Indirect Stainless Steel Cylinders from 150L to 250L. An Electric Boiler on a wet central heating system presents all the controllability offered by a gas fired central heating system. Using standard pipe-work, conventional wet system radiators and thermostatic radiator valves the boiler, being 100% efficient and fully modulating, will take the same amount of time to heat the property as a gas boiler. As no flue is involved and no gas analysis is required the installation of the system will be a lot quicker than that of a gas system boiler.

When an Electric Boiler is used for heating a property there will also be a requirement for domestic hot water. Although electric instantaneous water heaters are available, if the property has a bath then it is likely that a hot water cylinder will be required.
