The Ultimate Solution for Electric Central Heating

CometFusion

The Fusion range of electric boilers are widely

acknowledged as being the most complete

boilers on the market today. They offer the

perfect solution for properties with no access to

a mains gas supply or homes which have gas

boiler restrictions e.g. listed buildings and

bed-sit sleeping areas. They are also commonly

used in rural areas as replacements for oil and

LPG boiler systems.

These 100% energy efficient products are traditionally

installed by professional heating engineers throughout

the UK in typical properties such as apartments,

domestic dwellings, holiday homes and light commercial

properties. Because the Fusion Boiler is so reliable and

affordable, the range is specified by numerous Social

Landlords as the preferred option when replacing

storage heaters and other outdated forms of central

heating.

The Fusion range has been developed over the years to

offer a ‘Plug and Play’ solution to meet the demands of

professional installers and the various problems presented

by the different property types in the UK. Originally a

single Fusion Standard Boiler, the range has grown to meet

the increasing demands of Building Regulations and the

need for renewable products within the UK.

At EHC we are committed to producing the finest

products to meet our customer’s needs. After months of

consultation with the many engineers that install the

Fusion Boiler on a daily basis, our Design Team

endeavoured to improve this award winning Product.

The Comet Electric Boiler is the outcome of many hours

of product development which has taken Electric Boiler

Technology to a new level. This outstanding Boiler has all

the hallmarks of the traditional Fusion range however

with its improved appearance and size coupled with state

of the art components it is without question the best

value Electric Boiler on the market today.

Apart from its modern sleek design the key

developments within the unit include an

Automatic Bypass, Digital Pressure Sensor,

Integral Magnetic Filter and Stainless Steel Heat

Exchanger. The Comet range includes 6, 9, 12 and

14.4kW models in single phase and a 24kW

3- Phase model.

All boilers within the range are suitable for

Wet Systems including Underfloor Heating.

Our range of Electric Boilers provide complete peace of mind for reliability, performance and safety

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 digital pressure sensor

within the unit allows you to take an accurate reading of

the system pressure at all times.

The control panel also enables the installer to utilise the

inbuilt self diagnostic feature during installation or routine

maintenance.

The operating temperature of the boiler can be adjusted

using the control panel and range from 20 degrees through

to a maximum 85 degrees.

Our single phase boiler outputs are 6kW, 9kW and

I2kW. The I4.4kW is available for properties that require

a higher output.

For multiple boiler installations it is also possible to

install the boiler in series to suit non domestic situations.

In light commercial properties with a 3-Phase electricity

supply, we supply a 24kW output boiler within the

Comet range.

Due to the proven reliability of our products we have no

hesitation in offering a 2 year warranty for both Parts

and Labour.

M e r c u r y R a d i a t o r s Can be installed as part of an Electric Wet Central Heating System

The EHC Mercury radiator range is a unique

concept in wet system radiators. An aluminium outer

case conceals an internal copper pipe heat exchanger

which transfers heat to the radiator culminating in a

high performance and energy saving heater.

Aluminium conducts heat 4 times quicker than steel

which enable our radiators to reach temperature much

faster than steel radiators. Additionally the design of the

product ensures that the surface area does not get

burning hot to touch.

With the benefits of both Convection and Radiant heat

you will enjoy added comfort throughout the home. This

contemporary designed radiator is suitable for use with

all types of boilers: gas, electric, oil, solid fuel and LPG.

Many of the new generation heating solutions such as

Air & Ground Heatpumps generate lower system

temperatures and as such require larger radiators to

provide the same room temperature as traditional heat

sources such as Gas and Electric Boilers. The internal

design of the Mercury Radiators makes them the perfect

solution when installed with Heatpump systems.

Mercury radiators are constructed to provide all

the benefits offered by Low Water content

appliances as less water within the system adds up

to reduced running costs.

These energy efficient radiators use a fifth of the

water used by a standard steel panel radiator of

the same size. This results in annual energy savings

of up to 15%.

Due to the ultra lightweight design of the radiators, all of

the range are easily positioned as the lightest radiator is

3.9kgs with the heaviest being 13.4kgs.

The design of the radiator ensures that there is no

likelihood of internal corrosion of the radiators.

Available in Brilliant White, we offer a range of sizes and

with a choice of either standard height or low profile, a

radiator size for almost every application is available.

The Mercury radiators can be installed as part of an

Electric Wet Central Heating System and as such we

would recommend the Comet Electric Boiler which also

boosts Low Water Content heating benefits.

With the various alternatives available on the market

today choosing the right option can often be confusing

and as such our highly experienced staff would welcome

the opportunity to discuss all your heating requirements

and advise you accordingly.

All EHC Mercury Radiators are guaranteed for 15 years.
