More Heat from Hot air system
I have a forced hot air heating system. House is a small cape. About 1500 SF living area. I. use about 550 Gallons of heating oil in a season. With oil at $4.50 per gal.I want to try to squeeze more efficiency out of the system. Furnace is 24 years old. I know the new burners have a pre and post purge / ignition that helps increase efficiency but I question if a new burner would gain much except in the few seconds of start up and shut down I have been impressed with the Riello burners but I do not know if it would be cost effective to change from the Beckett AR that I currently have.
The duct work always seems pretty warm down cellar. I was thinking of increasing fan speed to move more air through the system. Would this require resetting the fan controls for fan off and fan on?
Opinions and advice are most welcome!
Best Regards
