Using propane exhaust to heat underneath?

my idea has merit... aka inter-coolers for turbocharged engines...

its just Work and money.
maybe someone will come up with a cheaper way... and for Homes.. water heaters... and such.

just like my idea an a engineer fine-tune a rear bumper stiffener with under body spare tire mount for a bicycle mount.

people here called me and my friend (engineer) crazy and dangerous..

as long as the dangers are understood and addressed....
ever LOOK at an installation of a HOUSE water heater (gas)... most have a 2 inch gap between its exhaust and the remaining piping to exit the house. so its possible for exhaust to exit pipe and fill your home.

Correct ...there is that possibility.
Water heater manufacturers use a gap between the top of the water heater flue and the vent connector pipe above it in a regular water heater to pull additional air into the upward flow of combustion air to help it exit more efficiently.
"back drafting" could occur if hood was knocked of of alignment OR if vent was blocked.


Yes you could attach a duct to furnace exhaust and run that duct to an enclosed/skirted area.
But that furnace exhaust would NOT provide any heating to that skirted are.....just NOT enough latent BTUs in that exhaust -----it WILL turn cold within a few feet of furnace exhaust port

That is the major reason it will not work...regardless of the dangers of Carbon Monoxide

Wet cold exhaust that will be end result.
