I have stove envy. Modern Stokers sound great, I'm saving money now with coal the old way, but as soon as I could I want to go with a stoker. I’d love to go with a stoker boiler.
This is how I do it. Here is a link to my post yesterday about my stove and collector. I'll elaborate a little more.http://nepacrossroads.com/post5691.html
The fans are adjustable together, they are rated at 420 CFM and up to ~275 degrees. 840 CFM total, they run 24x7. If it’s cold and/or if I need the 2nd floor warm, they will be blowing max. I know a single 6 inch adjustable going into each second floor duct will help. But, I didn't get that far yet.
I didn't get anywhere with cold air returns either. The main and only cold air return (done before this was my house) actually acts as hot air now, as it blows the hot air though the gas furnace, past the heat exchanger, down into the cold air return, and up. Its only cold air when the gas furnace is running.
There are forced hot air collectors & fans sold by some stove companies, and some stoves have huge blower fans and thermostats. I want to know what a pro hooks these in tandem with existing hot air furnace. Can anyone chime in with this one?
