Description
EHS Flex 24kW Three Phase Electric Combi Boiler (24000C Flex) – ALC-3PCO-24F
The EHS Flex 24kW Three Phase Electric Combi Boiler is a compact, modern electric boiler designed to deliver reliable central heating and instant domestic hot water without a flue or gas supply. Built for simple installation and low maintenance, the Flex range is ideal for properties where gas is unavailable or where homeowners want a cleaner, future-ready heating option.
With range-rateable output (12kW to 24kW), the boiler can be set to match the property’s heat loss and hot water needs, helping reduce unnecessary energy use. Quiet operation, a modern control interface, and minimal moving parts make it a practical choice for long-term performance.
