Ducane Lowboy Model Number RLBF/R80C Oil Furnace Price

The Ducane Lowboy RLBF/R80C oil furnace is a good fit for tight spots and delivers reliable heat at an affordable price.  The Lowboy design has a larger footprint but is shorter in height, making it a popular choice for crawlspaces and other locations where space is at a premium.  Models range in efficiency from 81% to 83% depending on the size of the furnace.  That’s about average for oil furnaces though there are models on the market that offer up to 87% efficiency.  If you rely on your oil furnace from fall into spring, choosing a more efficient model might be a better long-term choice.
