Many homeowners think of a heating system as “the monster in the basement,” but in reality, heating systems are not as intimidating as they may seem. In this class, we’ll cover hot water, forced hot air, and steam systems. We’ll explain how the furnace or boiler generates heat and how it is transported to your living area. You’ll receive answers to questions such as, “Why are some rooms in my house cold and others hot?” and “What is that banging I hear when the heat comes on?” We’ll also discuss ways to improve energy efficiency, review the cost-effectiveness of insulating pipes, and demonstrate how to do preventive maintenance and adjustments.
