"Any of the various energy modeling programs would give you a starting place. Model the ducts in various places and with different insulation levels.   I know you will not forget to seal the ducts."

John Nicholas replied to Jignesh's discussion Efficiency of furnace
"That is why gravity systems are much less popular then 50 years ago.   It could easily be improved by installing a chimney liner in that huge masonry chimney to reduce the amount of draft needed and the need for keeping it warm. You could…"

John Nicholas replied to Jignesh's discussion Efficiency of furnace
"System Efficiency is great.  Not much use, if you don't intend to fix the various problems with the system.  Not much use for comparison shopping for a new unit. If you are energy modeling, it would give you a great check on the duct…"

Most homes in this area have a gas fired natural draft hot water heater. They come complete with a draft diverter.  The purpose of the draft diverter is to send the exhaust gasses (containing Carbon Monoxide, Sulphur Dioxide etc) into the home if the chimney or flue doesn't allow them to go up.
