I currently have an outdated natural gas furnace that I am not happy with. Because of the extremely cold and long winters where I live, I rely on the heating system for half the year. The heater is not energy efficient and seems to run constantly. Despite setting the thermostat as low as possible, I spend a fortune on monthly energy bills. Every time the furnace starts up, it rattles and screeches, then blows a tremendous amount of dust from the vents. I continually need to vacuum and dust, and there’s often an oily film on the windows from the gas. The heated air blows from the supply vents and then rises straight up to the ceiling. There is severe temperature stratification, which leads to discomfort. Plus, I think the ductwork is leaking because some rooms are always warmer than others. Eventually, I will need to replace the furnace with a brand new, more efficient system. I am concerned about safety issues and health risks from contaminated indoor air quality. I wish I could afford to tear the whole furnace and ductwork completely out and switch to a boiler. Boiler heating is far superior to a forced air system. A boiler uses water to convey heat energy. Water heats up more quickly and retains heat longer, making a hydronic system far more energy efficient. Plus, this type of system is totally silent, doesn’t add any contaminants into the air, and maintains a very even temperature. It is also easy to set up a boiler for zone control, allowing personalized temperature settings in each room. There’s no need to heat empty rooms, and the temperature can be adjusted to meet various requirements.
