You can capture that heat with a high efficiency condensing furnace.
Furnace intake and exhaust separation.
My carrier furnace has two pvc pipes that go through the basement wall and up the side of the house.
Exhaust outlet ml193df combustion air intake inside of house exhaust combustion outlet air intake outside of house ml193df shipping and packing list package 1 of 1 contains 1 assembled ml193df unit 1 bag assembly containing the following.
The easy answer is oxygen is a key element in combustion therefore your furnace needs air.
Furnace intake and exhaust pvc.
Intakes should not be located directly above any wall exhaust or vent.
Intakes must be protected against rain and pest entry with durable rust and rodent proof materials.
Also known as the induced draft fan this one has a fan that is located on the end of the pipe.
It will draw in air for the combustion and then expel the fume outside.
At the top of the pvc pipe the intake has one 90 degree fitting so the opening is pointed straight out to the side of the vertical pipe.
Never pitch the exhaust pipe down ward toward the outdoors.
This is another affordable option for the heating solution.
The exhaust system typically uses metal venting often routed into a chimney stack to exhaust the combustion gases created in the furnace fire chamber.

A gas furnaceneeds approximately thirty feet of air for every foot of gas used.
Provide at least a 1 4 inch per foot upward pitch for horizontal exhaust vent piping to allow the condensate to drain back down into the furnace.
Irc 2006 section m1602 2.
Since the exhaust pipe is running on a sidewall the fan works together with the furnace.
Wall intakes must also be 10 feet from any exhaust fan discharge outlet unless that outlet is 3 feet or more above the intake location.
High efficiency condensing furnaces should not be vented into a chimney.
This is roughly the equivalent of running a bathroom exhaust fan into your furnace s combustion chamber.
Supplying makeup air can help natural draft appliances by compensating the effect of the powered exhaust appliances and equipment in the house including fireplaces exhaust fans ventilation systems clothes dryers and similar appliances and equipment.
