Furnace vs Boiler in Kennebec County, Maine

When a furnace makes sense

If your house already has ductwork, a furnace is the simpler choice. It heats the air directly and pushes it through the vents you already have, and with nine months of heating ahead of you each year, natural gas keeps the running cost reasonable. At 13°F on a winter night, a furnace can bring the house back up to temperature quickly once it kicks on.

When a boiler makes sense

If your home is heated through radiators or pipes in the floor instead of vents, a boiler is the one built for that setup. It runs about 5% cheaper than a furnace here, and it holds heat steadily through the long, cold nights Kennebec County gets from December through February. That steadier heat is worth something when winter lasts nine months of the year.
