I'm hoping one of you might be able to help me out with a problem I'm having with a Reading Juniata stove.
Bought this stove used and did a bunch of work on it. Regasket, full-time combustion air, outside combustion air, baro, mano, Power-Vent.
The problem is that at a mid-burn, the flue stack will get close to 300 degrees while my convection air hovers around 100.
I have an Alaska stove upstairs and the stack never gets that hot. It also sips coal (a bag a day if I push it), while the Juniata gulps it down.
The internal workings of the exhaust are pretty simplistic which I think is the problem. There is just a single sheet metal baffle that the exhaust flows around on its way out of the stove. I'm thinking about adding some complexity to the exhaust path to try to get more heat up into the exchanger before it vents out.
In this rudimentary drawing, the plate I am talking about is the green line in the cross section view. The second drawing is a plan view of that same plate and the blue line represents what I'm thinking about doing to it by adding some flat steel standing on edge in the pattern shown.
There is a concern about restricting the flow too much, but even with my baro set all the way down to 0.02 AND ADDING a washer to the weight, my manometer still reads 0.04" measured a couple inches up the stack from the top of the stove. So I think I have room to work.
I thought about maybe taking some pieces of broken fire brick and trying to just close off some of the front opening over the plate for starters to see how that helps.
I'm looking for advice here....
I can't see how running twice as much coal for half as much heat leaves me any better off than I was when I just had my trusty Alaska heating the main part of our house.
Thanks in advance!!
