ElectromaxElectromax 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
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
Domestichotwater isprovidedbya180 litreunventeddirecthotwater cylinderwhichismanufacturedfromDuplexstainlesssteelformaximumstrengthandlonglife. Duplex stainless steel offers a superior resistance to corrosion especially inaggressive water areas, compared with copper, glass-lined steel and some lower grades of stainless steel.
BecauseDuplexisalowcarbon,highchromiumcontentalloy,itresistsallformsofcorrosion 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.
Thewaterisheatedbylong-lifeSuperloy825alloysheathedelementsincorporatedinto 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 andWeekend 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,boileron/offswitch,domestichotwateron/offandboostswitches.
Running costs
There are a number of off-peak electricity tariffs now available which provide a range of lower cost options for electricity used for heating and hot water. The two most common tariffs are Economy 7 and Economy 10. Types of meter and tariffs will vary by property and region. The following information is for general guidance only.
Economy 7Two ratemeter installed in property. Units used at night (during off-peak time*)charged at lower rate than those used during the day.
Economy 10†
Only onemeter installed in each property. All electricity used at off-peak timeschargedat the lower rate (suchaswashingmachines,dishwashersetc).Off-peaktimesgenerallysetformidnight–5.00am;1.00pm–4.00pm;and8.00pm–10.00pm.
*”Night” means the 7 hours that the local distribution company in your area chooses between 10pm and 10am. “Day” means at all other times. †Not available in all areas, and details may vary by area.
