Because I live in an section where frigid cold, windy & wet weather is the norm, a boiler is the ideal furnace. The main drawback of a boiler is the lack of any cooling capacity. It’s strictly a heater. That isn’t a problem for my location, however our Winter season tends to linger for more than half the year. All of us often require heating to get through the frigid Spring & fall seasons as well. I’d love an a/c for about two months, when the heat & humidity become brutal. Instead of investing into a centralized cooling system, I spent a few hundred dollars on window a/cs for the bedrooms. That’s all both of us need. It’s far more important to me that my new home is equipped with a furnace that can actually handle temperatures down to negative twenty-several degrees. I’m thankful that the boiler is especially powerful, reliable & can be expected to outlast other types of furnace. It uses water instead of air to transfer heat, which avoids troubles with insufficient humidity. The closed loop system salvages the same water & eliminates the risk of air contamination, rather than blowing overheated air into the room, a boiler links to radiators, radiant flooring or baseboard gas heating systems to infuse heat into the air. This process is more gentle & won’t cause stratification. There is actually little difference in the temperature down by the floor & up by the ceiling. Another fortune of a boiler is the easy set up of zone control. A temperature control in each room allows customized temperature settings. I am not paying to heat empty rooms & yet can cater to the exact needs of each space. I love that the boiler operates quietly & is super clean.
