Central heating
Electromax is suitable for use with wet radiator or underfloor sealed heating systems. This 9 kW boiler is powered by mains electricity. 

Domestic hot water

Domestic hot water is provided by a 180 litre un-vented 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 gage, boiler indicator LEDs, boiler on / off switch, domestic hot water on / off and boost switches.

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 7
Two rate meter installed in property. Units used at night (during off-peak time) charged at lower rate than those used during the day.

Economy 10:
Only one meter installed in each property. All electricity used at off-peak times charged at the lower rate (such as washing machines, dishwashers etc). Off-peak times generally set for midnight–5.00am; 1.00pm–4.00pm; and 8.00pm–10.00pm.
