EHC COMET Electric Boiler 12kW

Comet Electric System Boilers are designed to eliminate unnecessary external plumbing and pipe work. They are the ideal choice for wet central heating and underfloor heating systems.

All Comet Boilers can be installed for Heating only or Heating and Domestic Hot Water purposes when used with an 'S' Plan configuration in conjunction with the EHC Twin Channel Heatpack.

To ensure maximum efficiency, all Comet Boilers incorporate six stage heating using a stainless steel heat exchanger. This unique facility will modulate the Boiler to reduce electricity consumption and running costs.

The Comet System Boiler has been engineered to include the pump, auto-air vent, expansion vessel, auto-bypass and expansion vessel within the compact casing. For added safety the Boiler also incorporates a High Current Thermal cut-out for added protection.

The easy-to-use control panel provides operating temperatures for flow and return, system flow rate and kW output information and enables the installer to utilise the inbuilt self-diagnostic feature during installation or routine maintenance.

The operating temperature of the Boiler can be adjusted from 20°C-85°C.
