More than 64 million homes in the U.S. use natural gas to supply them with heat during cold weather, and most of these homes use a furnace for the job. It’s not surprise that gas furnaces remain the #1 option for winter comfort: they can deliver high levels of heat and deliver them fast—all without putting a huge drain on a household’s budget.
Using natural gas, however, brings with it a few cautions. Although gas furnaces are constructed to be as safe as possible, there are potential hazards they can run into. The most concerning one is the cracked heat exchanger. When this happens, can the problem be repaired? Or is it time for a new furnace installation altogether?
Furnaces are the top type of heating system in the country. The majority of furnaces use natural gas to create heat, although they draw on electricity to power the blower fan and the ignition system. (Which means that, sorry, your gas furnace won’t work during a power outage.)
The fireplace is the oldest type of heating system that’s still in use. Fireplaces developed in the Middle Ages inside drafty castles because they allowed for the better direction of heat than the large central fires that buildings once used. The fireplace also created radiant heat of the bricks and stones around them, adding further warmth to a space.
