My Yukon EHD came with the 210* link...and believe me, that monster ran higher duct temps than any Kuuma! (had to run 'er hot to keep the chimney from plugging up in less than 48 hours
dude... don’t do it. The liability is insanely high. Super easy for some investigator to blame this device for causing the fire that burned the house down and killed the children. You could lose everything and end up in jail.Any others that would be interested in an emergency heat dump? Considering making a few...
No, there is nobody left in the forced air wood furnace world that gives a rip about a EHD...they all just tell you not to install in a down-flow configuration, etc, etc...but I hear ya...liability/headache/hassle would be the main reason I don't do it, if I don't.There’s a reason that the big boys with insurance and lawyers won’t build these things.
If free labor equates to a free heat dump count me in for sure. I could probably run up there one weekend and help you if you want.I thought you were working from home?!
Not yet...wanted to see how much interest there actually is first...have some ideas in mind for design...probably 12" x 12" (tall/wide) x 8" ish deep.
As far as the link, I was planning on the same one that came on my Yukon EHD https://www.mcmaster.com/1147A19/
That you could make of parts you can buy today. A normal (large) register on the floor above, with an upward duct controlled by a normally open electric duct damper. Power goes off, damper opens.It may not be pretty, but a dedicated opening close to the plenum within the living space feom the main trunk would be ideal. Power goes, trap opens into floor above and gravity takes hold. Our previous furnace during an outage would get so hot, water droplets would dance on the surface of the ductwork above it. Nothing that I would ever wish on anyone! But 6 cubic feet of firebox burning white hot during an outage was a fire waiting to happen.
