Although forced air furnaces are the most popular choice for residential application, I guess that hydronic heating is better.
- A natural gas furnace relies on ductwork to transport heated air into the multiple 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 bad 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 downside of a furnace is unsatisfactory humidity. The blast of heat dries out the indoor air, causing health problems such as chapped lips, respiratory infection, headaches, sore throat and frustrated dust sensitivity and asthma symptoms. It can disfigurement hardwood floors, moldings and furnishings. By comparison, a boiler uses water to transfer heat energy through a series of sealed pipes. There is no opportunity for the water to escape or for pollutants to enter. Boilers are suggested for people with respirator sensitivities, then hydronic heating doesn’t make any noise, maintains a cleaner house 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.
