I converted my garage to an office. I use one of the former bays downstairs. It’s 12 x 24 and it’s heated with a propane space heater. My wife has an office upstairs that’s 18 x 24, and it’s also heated by a space heater. Here’s my challenge. I would like to use a woodstove located in the downstairs office to heat both offices. The downstairs ceiling is well-insulated, so heat wouldn’t just make it up there on its own. And I don’t want to just open up a section over the stove as a floor grate because we don’t want to hear each other. I’m a writer and on the phone a lot, and she’s a weaver with students. So the sound separation is important. I’ve heard of boiler stoves in the U.K. but have never seen anything like it here. What I’d like is something like that. It could heat my smallish office and also heat water that would then circulate to baseboard heat upstairs. One last difficulty. We don’t have plumbing to the garage, so the circulating liquid would have to be anti-freeze. Does anybody make a boiler stove that would work like this? If not, has anybody here fabricated a similar system? Thanks.
