A condensing combination boiler is combined central heating and a water heat boiler. Unlike traditional central heating boilers, whose role is to heat up water stored in a separate cylinder, a combi doesn’t produce stored hot water, but rather continuous and unlimited amount of hot water on demand.
The boiler water temperature may reach 180°F during a domestic hot water call. This helps in fast domestic hot water recovery. In most residential installations, the domestic hot water load is greater than the heating system load. What “Domestic Hot Water Priority” does is allow the use of a smaller size boiler to do both jobs.
Where the central heating boiler also heats a tank of domestic water supply, the boiler needs to be sized to include keeping the tank full of hot water while not disrupting the hot water for the central heating.
