How does a hot air heating system work?
How does a hot air heating system work? Warm air heating systems work by passing cool air through a heat exchanger fuelled by gas or electricity. Once warmed, the air is then blown into rooms through vents in the floor, walls or ceiling. As the system heats the air directly, the warm-up time is relatively quick. How does air get into a forced hot water heating system? Water has compressed air in it. As the water flows through the system, the air settles in to high spots. Over time the resulting air pockets reduce the efficiency of the hydronic heating...
