Side vs. Roof Vent Heater

[Tuhlmann]

I apologize if this has been beaten to death...

What are the functional advantages/disadvantages of each? I’m ambivalent about the esthetics, so I’m just interested in practical differences and their consequences.

Roof (vertical) is cheap b-vent

Side (horizontal) is expensive CAT III stainless

My vertical DuraVent kit was under $70 shipped

Code compliant side vent kit is about $300. I have one since a roof vent would have to go through my 2nd story and attic.

natural draft or direct vent?

In snow country, I will pay extra for the side vent.

I agree wholeheartedly. Mine is vented out the back wall of the garage and I am really happy with that. But to be fair about this, I have a second floor on the garage for storage, so in my case it just made more sense to go out of the back wall.

Many of the roof vents here in the snow belt get torn off by snow sliding off steel roofs. I don’t think any established hvac guys will install a roof exhaust on a steel roof anymore.

Probably not a problem in se Wisconsin though, where the winters are relatively mild.

Have a b-vent through the roof, about 3’ tall (needed to be 2’ above ridge) and I made two braces about 90 degrees apart lag-bolted into the roof. I don’t want a hurricane tearing it off.
