6kW Electric boiler

Our 6kW electric boiler model option for central heating, designed for either radiators or underfloor heating systems and hot water via an indirect hot water cylinder, is a zero-emissions boiler with a maximum efficiency of 100%.

They are ideally suited for small homes, flats, apartments and annexes with standard radiators or underfloor heating systems (radiant floor heating) within existing properties. It is a highly effective alternative solution for wet central heating systems in locations that are not on the mains gas supply.

With no emissions, no chance of carbon monoxide poisoning, a rapid response to the central heating demands, flexible installation, and fewer moving parts, there is a lower chance of an issue occurring and less maintenance cost associated.

Our 6 kW electric boiler products are easy to operate, and installation is generally effortless, both time-wise and trouble-free, and there is no requirement for an annual safety certificate. They are also 100% energy-efficient for the heating elements.

They are actually a 9 kW output boiler that can be set to a lower output of 6 kW, which is handy if you want more output in the future.

Single phase electric supply

Our 6kW electric boiler option is generally powered on a 240 Volt single phase electrical supply to power the immersion heaters. When requiring a 6 kW output, the boiler has a rated electrical demand of 26.1 amps on a single-phase supply and requires a 32 amp breaker.

But this boiler can also be used on a three-phase 415 volt supply as well; in this case, the amps required are 8.7 amps per phase of the three phases.

Small electric boiler

Our 6kW electric boiler is small in dimensions, i.e., depth, width and height, and installation in small spaces or locations is possible (remember, no flue system is required for electric boilers). This enables you to choose your preferred installation location within the property (anywhere you can run the cables and pipework to the boiler within the property).

For example, gas or oil boilers must be installed on an external wall, as they require a flue exhaust system or chimney to vent the products of combustion to the external air, i.e., no flue or fuel tanks.

6kW Electric Boiler Technical Specifications 

Boiler Width = 475 mm

Boiler height = 638 mm.

Boiler depth = 238 mm 

Boiler empty weight = 27 kg for this electric system boiler

These electric boiler products come with a 2-year warranty and are designed to work for many years on a wet electric heating system (radiators or underfloor heating) and an indirect water heater. Please note there must be a magnetic dirt filter and air separator installed on the central heating system.

Boiler modulation

This electric system boiler offers settings of 1kW to 9kW and can be set to a specific maximum output, i.e., 6kW heating output. The boiler adjusts its output within this modulation range based on the heating system’s requirements.

This electric boiler has the following power output steps:

1 kW, 2 kW, 3 kW, 4 kW, 5 kW, 6 kW, 7 kW, 8 kW or 9 kW

So when set at 6 kW, the modulation rate is 6:1, which results in close heating load management and an accurate match to the heating system demands, providing added comfort and lower running costs. Similar products do not offer anywhere near this level of boiler output modulation.

Central heating

Our electric boiler will work on either radiators (with or without thermostatic radiator valves) or an underfloor water heating system, with a selectable outlet flow temperature range from 20°C to 85°C. These products are designed to work with a heating system that has a minimum working pressure of 0.5 bar and a maximum working pressure of 3 bar. You can control these units with a standard room thermostat or an app-controlled room thermostat and programmer operation.

Domestic hot water solutions

This 6kW electric boiler can also be used in conjunction with an indirect water heater, allowing you to have a complete electric heating system.

Electric combi

You’re not going to get a 6 kW electric combi boiler that can produce a suitable or the required hot water flow rate to even satisfy even a toilet tap, let alone a shower or bath. You simply can’t get the power required to heat hot water instantaneously for a 6kW electric combi. Electric combi boilers simply won’t work at this small kW output.

One installation option is to use a 6kW electric boiler for the central heating in conjunction with an indirect water heater cylinder for the domestic hot water. Like so schematically

 

Alternatively, one can use only the 6kW electric boiler for central heating and hot water when combined with a separate direct unvented hot water heater for domestic hot water. We supply a full range of direct unvented cylinders which are detailed here – Direct unvented hot water cylinders
