Can boilers heat domestic water?
Hot water from the boiler is circulated through radiators or a hydronic heating system to warm the ambient air. The traditional boiler water may also be used for domestic hot water by directing the water through a separate, integrated water heating unit before routing it to a fixture, such as a faucet or shower.

Can you use the same boiler for both hot water and hot water?
