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. If you are unsure of the Model and Output you require please feel free to contact our Sales Team on 01698 820533 or visit www.electric-heatingcompany.co.uk 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. Mercury Combi Boiler The Mercury Combi is the Premium Electric Boiler Solution for Heating & Hot Water with the added benefit of Weather Compensation & Advanced Service Diagnostics *Our 5 Year Warranty is offered on Boilers which are registered within 60 Days of purchase, For full Warranty T&C’s please visit our website.

Inbuilt Programmer ErP Hot Water Control ErP Smart Pump Weather Compensation Latest Features Include Weight 107kg D C It is a fully controllable 24/7 packaged unit housed in an elegant enclosure and is available in 9kW, 12kW or 14.4kW Outputs with an internal 140 Litre Duplex Stainless Steel Hot Water Cylinder. The Boilers internal plumbing is configured to an ‘S’ Plan design that also has an in-built magnetic filter for added protection and includes pre-plumbed Expansion Vessels for both the Heating and Domestic Hot Water circuits. Supplied with an external Tundish and Domestic Hot Water Control Valve and a fully programmable Controller and Wireless Room Thermostat to provide full control of both the Central Heating and Domestic Hot Water. The Boilers inbuilt controller “Navigation Button” gives you easy access to the boilers settings by simply scrolling through the menu. There are various pre-set times that can be easily adjusted to suit your heating & domestic hot water requirements. For ease of installation a Wireless Room Thermostat is supplied which can be located anywhere within the property. The unit has In-built Weather Compensation which will automatically modulate and reduce the Boilers input temperature in relation to the external temperature which reduces Boiler cycling and could save up to 15% energy usage. A further energy saving measure would be to add our optional Titanium PV Immersion heater to the Cylinder which when connected to a Solar PV diverter will automatically start heating the cylinder within the unit.
