Electromax
Combined electric boiler
and domestic hot water store
Electromax
Electromax provides efficient electric wet central heating
and domestic hot water with the comfort and control of
gas-powered systems, making it a perfect solution for over
two million homes in Britain with no mains gas supply.
Electromax includes a programmable room thermostat to take full
advantage of off-peak electricity rates. It uses standard radiators
and thermostatic radiator valves to reduce the cost of installation.
To complement the range an underfloor heating version is also
available. With long-term costs in mind, there is no need for the
considerable expense and inconvenience of an annual gas safety
certificate.
Electromax comes with a 10 year cylinder guarantee and a two year
guarantee for the boiler and all other controls with on-site service
support.

Central heating
Domestic hot water
Electromax is suitable for use with wet radiator or
underfloor sealed heating systems. Typical system
layout given below is for illustrative purposes only.
Domestic hot water is provided by a 180 litre unvented direct hot water cylinder
which is manufactured from Duplex stainless steel for maximum strength and long
life. Duplex stainless steel offers a superior resistance to corrosion especially in
aggressive water areas, compared with copper, glass-lined steel and some lower
grades of stainless steel.

Because Duplex is a low carbon, high chromium content alloy, it resists all forms of
corrosion including pitting, crevice corrosion, uniform corrosion and stress corrosion
cracking, without the use of a sacrificial anode. In addition, the combination of
tungsten inert gas and laser welding coupled with the special post-weld processes
ensures the same level of corrosion resistance and mechanical strength as the
parent metal. This ensures the longest possible working life for every cylinder.
The water is heated by long-life Superloy 825 alloy sheathed elements incorporated
into an easily removable heater plate, making replacement simple, if necessary.
Electromax is supplied with a programmable room thermostat which controls the
time periods that the boiler comes into operation and the room temperature.
Offering up to three ‘On’ and three ‘Off’ periods per day and Weekday and
Weekend programmes, the user is able to take advantage of the most appropriate
off peak tariff best suited to their needs.
The control panel on the unit includes a system pressure gauge, boiler indicator
LEDs, boiler on / off switch, domestic hot water on / off and boost switches.

Electromax solar
Solar energy is a free, natural and inexhaustible resource
that we can exploit as the technology to do so becomes
more affordable. Electromax Solar is a prime example of
this new eco-friendly technology.
Electromax Solar, combined electric boiler and domestic hot water store, uses a sustainable
energy source which is free and natural. Providing an attractive lower carbon option for
specifiers, developers, home owners and tenants alike the Electromax Solar reduces the
amount of electricity required to generate domestic hot water. In addition to reducing
carbon emissions, real cost savings can be made over the medium and long term when
switching to sustainable energy sources.
The Electromax Solar is ideal for a range of domestic properties and especially
suited where there is no mains gas supply. An installation template is supplied to
enable pipework to be pre-installed prior to siting the boiler.
Electromax Solar is a fully packaged unit and comes complete with a 9kW electric
boiler, Duplex stainless steel solar thermal hot water cylinder (available in 185, 220
or 250 litre capacities) with a specially designed solar coil for maximum heat input
and efficiency, a pre-plumbed factory-fitted circulating pump, service isolation valve,
central heating and solar domestic hot water controls.
Both the solar hydraulic pump and solar controller are fully integrated into the
Electromax Solar resulting in a quick and neater installation ready for connection
to solar collectors. They are operated by a clear, multifunctional and easy to use
control panel with an integrated LCD display.
To complete the solar thermal installation, a choice of in-roof and on-roof flat plate
solar collector kits are available. Every kit is supplied with primary solar system fluid,
24 litre solar rated expansion vessel and connecting pipe kit.
Supported by our national service and technical support network, Electromax Solar
features a 10 year on-site parts and labour guarantee on its stainless steel cylinder
and two years on the boiler and controls. A specification and design service is
available through our Specification Advice Team on Tel: 01603 420220.
Whether in rural areas, new housing projects, multi-floor dwellings or one of the two million
homes in Britain with no mains gas supply, Electromax Solar offers the best solution for
comfort and convenience of wet central heating. The benefits of domestic solar thermal
hot water are powerful mains pressure showering and faster filling baths.
With the same comfort and controllability as a gas boiler, Electromax Solar provides central
heating only when required and is controlled by a programmable room thermostat which
can be set to take advantage of off-peak electricity tariffs and meet end user life styles.
It is available in both radiator and underfloor options.

Legislation
Energy consumption of dwellings, in particular space and
water heating have been identified as key areas to help
meet European and UK government carbon reduction
targets.
New regulations have been introduced (Code for
Sustainable Homes (CfSH), and existing regulations
tightened (Building Regulation Part L, Standard
Assessment Procedure (SAP)) to ensure that both
New Build properties and upgrades of existing
dwellings meet the latest energy efficiency requirements,
therefore driving down emissions and reducing the
country’s carbon footprint.
Installation of a solar water heater, whether as part of a
new build development or as an upgrade to an existing
property, plays a key part in increasing a property’s
energy efficiency and the Electromax Solar has been
designed with CfSH, SAP and Part L in mind.
The Electromax Solar total cylinder capacity (Vt) is made
of two parts: Dedicated solar volume (Vs) and auxiliary
volume (Vb) where Vt=Vs+Vb.

Ratings
Boiler: 9kW @ 240V (8.3kW @ 230V).
Immersion Heaters: 2x 3kW @ 240V
(2x 2.8kW @ 230V).
Dimensions
The dedicated solar volume (Vs) can only be heated by
solar energy. The volume has been calculated to ensure
the requirements of Building Regulation Part L and
SAP are met (Vs = 80% Vd where Vd = TFA or Vs = 25
Litres per metre squared of solar collector) if installed
correctly.
The auxiliary volume has been calculated to ensure that
on a cold day with low solar gain there will be sufficient
hot water for the dwelling as required by
BS 6700.
