12kW Unvented Dualheat Combination Boiler
Dualheat is an electric combi-boiler that provides domestic hot water – and powers ‘wet’ radiator systems. It combines the convenience of low-cost electricity, where available, with the comfort of radiator heating. Dualheat unvented units can be sited almost anywhere as it has no external flue, no fumes, no noise and no need for a space-wasting hot water cylinder. With few moving parts, maintenance is minimal. Unvented models supply hot water at mains pressure.
