Furnace vent question ...

All, My home has a high efficiency forced air furnace, with combusion air and exhaust through two PVC pipes (about 15' runs).

While at the heated pool in our neighborhood, I noted that the pool heater was ducted through what appeared to be a single pipe (pipe in a pipe), with the exhaust through the inner pipe and the intake through the outer pipe.

If I understood the arrangement, I could see a few advantages:

1) The inner exhaust pipe would have counterflow to the intake, and should heat the intake air somewhat. 2) The inner pipe had a screen over it, to prevent entrance of critters. I put 1/2" hardware cloth over my intake pipe to prevent the entrance of barn swallows, but it capped over with snow in the winter. This arrangement looked to be a little more robust.

Is this sort of arrangement available for a forced air furnace? What is this called?

Thanks, Chris

It's a concentric vent kit.

Concentric. Call your service people for an install pricing.

That might actually cost money.... If he had used a a real pro to inatall his furnace, instead of the lowest bidder, he would already *HAVE* one.

Benefits of hiring the lowest bidder.

I heard Neil Armstrong once in an interview regarding his second space shot & his first... The question was something about "what were you thinking during the final launch countdown?" His answer went something like: "We're sitting atop a very tall package of lowest government bids"
