With a combi boiler, you'll save on hot water costs. (In fact, according to a 2005 Green Affordable Housing Coalition report, combination water and space heating systems can reduce utility costs by 15 percent or more compared to standard installation of separate furnace and water heater systems.).f fed directly from the main water supply to the heat exchanger, the combi boiler can have an unlimited hot water supply as long as the boiler is firing. Combis manage to extract a larger amount of heat from the flue gases that escape from the flue system, which increases the combi's efficiency.
