Just a quick post about some changes I made to the heating system since my Wood Stove and Chimney post last November. After some very cold nights last winter (< -10F), it seemed that my Jotul 602 was having trouble keeping the cabin warm enough. I was worried that I might need to get a larger stove, and even started perusing Craigslist to see what might be available. I also spent some time researching potential fixes on various forums when I found the answer.
The problem was the double wall stove pipe from the stove to the chimney. I had originally installed it because I read that they created a better draft and required a smaller heat shield. In January, I installed a 22 gauge single wall one piece adjustable length stove pipe from Selkirk. The heat output from the stove after switching to the single wall pipe was dramatic. The Jotul 602 had absolutely no difficulty keeping the place warm after that. This was even with some questionable wood that I picked up from a local seller – this year I’ll be using some well dried elm from my own property.
The drawback to the single wall pipe was the need to scrap my existing heat shield – a couple of custom 3′x4′ galvanized steel panels – for a larger one. I was fortunate to find a reasonably priced solution when I visited a friend with a wood stove in his home. His heat shield was constructed from steel studs affixed to the wall, to create a one inch airspace, with 1/2″ cement board screwed onto them. While his was nicely tiled, I think I’m going to leave mine plain for now.
I’m already looking forward to my first fire of the season in a few weeks.
