Although forced air furnaces are the most popular choice for residential application, I think that hydronic heating is better. A natural gas furnace relies on ductwork to convey heated air into the various rooms of the house. Ductwork is notorious for energy waste. In the majority of homes, the duct system allows up to 30% of heated air to escape through holes, leaks at the seams and poor installation practices. Plus, the ducts tend to harbor contaminants that block airflow, reduce system efficiency and spread into the breathing air. As the heated air flows from the vents, it tends to rise straight up to the ceiling. It only drops down after it has cooled off. This not only creates uncomfortable stratification but requires the furnace to run more often and work harder. Furniture needs to be arranged to accommodate the supply and return vents. Another drawback of a furnace is insufficient humidity. The blast of heat dries out the indoor air, causing health concerns such as chapped lips, respiratory infection, headaches, sore throat and aggravated allergy and asthma symptoms. It can damage hardwood floors, moldings and furnishings. By comparison, a boiler uses water to move heat energy through a series of sealed pipes. There is no chance for the water to escape or for pollutants to enter. Boilers are recommended for people with respirator sensitivities. Hydronic heating doesn’t make any noise, maintains a cleaner home and doesn’t dry out the air. It provides a more consistent and gentle comfort. A boiler can link to any combination of radiators, baseboard heaters, radiant heated flowers, snowmelt systems and even towel warmers. Plus, a boiler accommodates any size or layout of residence and allows for zone control.
