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.

Our single phase Electric System Boiler outputs are 6kW, 9kW, 12kW with the 14.4kW available for properties that require larger outputs.

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 our 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 degrees through to a maximum 85 degrees.

In light commercial properties with a 3-Phase electricity supply, we supply 12kW, 14,4kW, 23kW and 39kW output Boilers. For multiple Boiler installations it is also possible to install them in series in a low-loss header configuration for properties with higher heat demands.
