Closing vents in unused rooms
My local utility had the following info on it’s web site regarding closing vents in unused rooms. Any contrary thoughts on this?
“It’s true that closing a vent or two may reduce the furnace’s efficiency slightly. But if you’re closing a vent to avoid heating an area that doesn’t need to be heated, the energy you save will be greater than the energy lost due to the slight increase in inefficiency.
Bottom line: If you don’t need to heat a room, close the vents in that room.”
