The EHS Flex 14kW Electric Combi Boiler (ALC1-1PCO-14F) is a compact electric heating solution designed as an alternative to traditional gas combi boilers in small flats, annexes and properties where gas is unavailable or a flue cannot be installed. This wall-mounted electric combi boiler provides both central heating and instantaneous domestic hot water from a single appliance, eliminating the requirement for a separate hot water cylinder.
The Flex range features range-rateable output from 2kW to 14kW, allowing the heating output to be limited according to the property's requirements. With a touchscreen control panel, near-silent operation, integrated pump and 5-litre expansion vessel, the EHS Flex 14kW offers a compact and straightforward electric heating solution for space-conscious installations.
