Unlike most electric boilers, all EHC boilers are designed to eliminate unnecessary external plumbing and pipe work.
The Comet boiler has been engineered to include:
- the pump,
- auto-air vent,
- automatic bypass and
- expansion vessel within the compact casing.
A magnetic filter is also pre-plumbed within the unit for added protection which will enhance the life of the boiler.
With the sleek design and integral pipework the boiler can be discreetly located in either a cupboard or wall mounted e.g. in the kitchen area.
To ensure maximum efficiency, all Comet boilers incorporate six stage heating using a single stainless steel heat exchanger. With this unique facility the boiler will modulate so that both electricity consumption and running costs are controlled through all heating cycles.
The easy-to-use control panel allows;
- both the installer and home owner to identify the operating temperatures on the flow and return, system flow rate and kW output of the boiler at any given time;
- the installer to utilise the inbuilt self-diagnostic feature during installation or routine maintenance; and
- the operating temperature of the boiler to be adjusted and range from 40 degrees through to a maximum 85 degrees.
The digital pressure sensor within the unit allows you to take an accurate reading of the system pressure at all times.
For multiple boiler installations it is also possible to install the boiler in series to suit non domestic situations.
