Electromax 6kw Electric Boiler 180 Litre Capacity 240V~50hZ Central heating
Electromax is suitable for use with wet radiator or underfloor sealed heating systems. The 6 kW boiler is powered directly by mains electricity.
Domestic hot water
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 programs, 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.
