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
