Combi Boilers: Domestic Hot Water And Home Heating
A Combi-Boiler is a high efficiency modulating condensing combination boiler with the capacity to supply both heat and domestic hot water for medium sized homes — enough hydronic heat for a whole house, plus hot water to run two showers and a dishwasher all at the same time.
