Vapor barrier on rear of Garn

After reading Rick’s post and others on hearth.com about overheating and steam I have a question. How do you handle the vapor barrier between the rear of the Garn and the outside cold wall? The manual says combustible materials must be at least 2” from the chimney. If there is not a vapor barrier, wouldn...

Future Garn Owner

This is my first forum. So if I do something that isn't proper etiquette please let me know. I have learned several things reading all the posting and they weren't all about the Garn. One thing that I learned was not to use CAPS. Thanks for that advice Jim k in PA. I have been looking at the...

Depth of Underground Piping

In various posts in the forums here, it has been mentioned that the depth of burial for the underground PEX piping is of the order of 30" (these lines are either the direct burial lines with insulation and encapsulation already incorporated into them, or the standard PEX piping with the use of closed...

I am lucky to have all this expertise available to bounce ideas off of. I've got a question for the group about doing an install with just a single loop, ie no heat exchanger just a manifold. The positives I know are lower cost and less complicated install, but am curious about negatives. I've...

Exhaust placement

My first post... Many thanks to those who have posted videos and photos. There are an enormous help! I'm currently designing a home to be built in central Wisconsin. I was wondering if you can run the exhaust straight up and through the roof, or if must be run horizontally through a wall. If it can...

considering a garn

I am considering installing a Garn to replace my old OWB. My current wood boiler feeds into a gas boiler in my basement, and the gas boiler controls the 3 heating zones. It should be a pretty straight forward connection as far as I can tell. Does anyone know where I can get a more detailed picture of...

Staying warm in Cold N. Michigan

This is my first winter heating with a wood boiler, and so far the only thing I can say is ... I Love It! You can click on my profile to get the full story of what lead me to my Garn, but long story short, It's efficient & basically easy to operate and maintain. We had it plumbed by late October...
