combi boiler

Dual-purpose water heater

A combi boiler is a compact heating unit that provides both central heating and hot water on demand, without requiring a separate water tank.

Common in British homes where space is limited, the system heats water directly from the mains when you turn on a tap: We replaced the old tank system with a combi boiler.
