Description
EHS Flex 24kW Three Phase Electric System Boiler – ALC-3PSY-24F
The EHS Flex 24kW Three Phase Electric System Boiler is a powerful and efficient heating solution designed for larger homes that require consistent central heating and reliable hot water when paired with an unvented indirect cylinder. Built as a modern alternative to traditional gas boilers, it offers clean, safe, and future-ready performance with zero emissions, near-silent operation, and no flue requirement. Its compact, wall-mounted design and intuitive touchscreen interface make it an ideal choice for properties where gas is unavailable or where homeowners want a low-maintenance electric heating system.
Product Application
This 24kW three-phase system boiler is suitable for medium to large properties with multiple bathrooms when used with an indirect unvented hot water cylinder. It delivers strong heating performance and works with radiators, underfloor heating systems, and renewable technologies such as solar PV, solar thermal, and heat pumps. With no flue required, it offers excellent installation flexibility and can be easily positioned in kitchens, utility rooms, lofts, or plant rooms. Pre-wired and fitted with an integrated pump and expansion vessel, installation is straightforward and efficient.
