EHC Mercury 19kW 3-Phase Electric Combi Boiler, MERCURY19KW

The EHC Mercury 19kW electric combi boiler serves wet central heating and domestic hot water in properties with a suitable three-phase electrical supply. Weather compensation and service diagnostics help manage system operation. It can also be used with compatible underfloor heating systems. The 19kW model is part of the Mercury range for properties without a suitable gas installation. Its three-phase supply requirement is an important distinction from the 12kW and 14.4kW single-phase Mercury models. Hot water performance depends on inlet conditions and the installed system. The Mercury range includes automatic power modulation and operating controls intended to match output to the system’s requirements. This 19kW version should be identified by its MERCURY19KW model code when comparing it with visually similar Mercury products. Confirm three-phase availability before purchasing, and ask the installer to assess incoming water temperature and simultaneous outlet use when estimating delivered hot water.
