Description

The Comet Electric Combi Boiler offers the comfort and convenience of wet central heating and domestic hot water from a single product installation for properties with no access to mains gas. The Comet Combi is the ideal solution for a quick hassel free installation providing heating and mains pressure hot water from within the same product housing. When it comes to electric combi boilers the Comet Combi ticks all the boxes where the performance of a gas combi is required. Due to domstic power supplies in the UK being limited to 100 Amp it is not possible for any electric combi boiler to match the same instantanious hot water performance and flow rates as a gas combi boiler without having some built in storage, therefor the Comet Combi holds a unique internal DHW storage of 144L at up to 30L/min with a rapid reheat time when utialised to supply baths and showers.

If the property has any electric showers installed EHC recommends for an EHC Shower Sensor to be fitted to each shower within the property.
