Mercury 12kW Combi Boiler

The Mercury Electric Combi Boiler is the Premium Electric Boiler solution for Heating & Hot Water with the added benefit of Weather Compensation & Advanced Service Diagnostics.

This Electric Combi Boiler provides a very cost effective alternative to electric storage heating, oil, solid fuel or LPG systems. It is the perfect solution to properties with no access to mains gas supply and homes which have gas boiler restrictions e.g. listed buildings and bed-sit sleeping areas. Not only is the Electric Boiler the ideal choice for wet central heating but is also suited to Underfloor Heating.

The Mercury Boiler outputs are 12kW & 14.4kW Single Phase, and 19kW & 26kW Three Phase. The operating temperatures of the boiler can be adjusted using the easy to use Digital Control Panel with adjustable temperature outputs ranging from 30°C-60°C (Hot Water) and 20°C-85°C (Central Heating).

Mercury Electric Combi Boilers are suitable for properties that have a Shower and Hot Water outlets for sinks.

It is not recommended that they are used for properties with Baths as generally the flow rate is insufficient to fill a Bath in a suitable timescale. In the event that there is a Bath in the property the Mercury can be used to Heat the Radiators and a Hot Water Cylinder via an ’S’ Plan configuration for Domestic Hot Water purposes.

If 3Phase Electricity is available our 19kW & 26kW Mercury Boilers would have sufficient flow rates to fill a Bath in a suitable timescale.

We also offer a comprehensive range of Electric Boiler and Cylinder packages designed to be affordable and bespoke to your requirements

The Mercury boiler brings a new era to the Electric Combi Boiler market with the introduction of External Weather Compensation & Bare-Wire Heating Element technology for Domestic Hot Water.

Bare-Wire elements are more robust in tackling the formation of lime scale due to operating at higher temperatures with a lower surface area.

The Mercury also features advanced service diagnostics via the main interface.

At EHC we recognise the growing demand for eco friendly heating and hot water solutions and all of our products are designed with this in mind.

Owing to the fact that Electric Boilers can be run from renewable resources such a solar power, it means that your boiler will run completely free from CO2 emissions.

Electric Boilers are also 100% efficient which means that for every 1kW of electricity you use, you will receive 1kW of heat.

Moving to electric is easy, as you don’t need to replace any of your existing pipework or radiators.

By 2050 the UK Government aim to generate emission-free electricity. Electric Heating will be a major facilitator in reaching this goal and in 2020 the Government pledged 40GW of wind generated electricity in the UK by 2030. This is enough electricity to power every household in the UK!

By moving to Electric Heating, with a renewable energy tariff you’ll not only be moving to carbon-free heating, but doing your bit to heat for a renewable future!
