Heat going out is fuel wasted. Don't forget that the PlatCat is also sucking cold air in from outside through every nook and cranny. The exhaust going out must be replaced by air coming in at a 1 to 1 ratio.

My point has always been that the PlatCat doesn't give any specs so we have no idea. Your opinion is valuable but is only conjecture. Your regulated furnace gives output and input BTU making it a piece of cake to know how efficient it is.
My point has also always been that if you are going to vent the exhaust - why waste the extra money on a platinum catalyst?
