Update: I found a KQ 480
Just about 2.5 hours away. I'm heading down tomorrow to look at it and make an offer. It doesn't have a water jacket, but plan to add that and the glass doors.
I drove for mine too. The Suppertime stoves are not quite as heavy duty. They are gauge steel. KQ uses 1/4 inch plate for firebox and top. The older ones have stainless oven and oven door interior.
The Amish use both. They do all night canning operations, where neighbors bring their products to a home with a Queen. The others warp, can bow tops, and latterly wear them out with high sustained temps. I figured if the Queen can do that, they are the heaviest duty and will take what we give it.
The glass is nice to see how the fire is doing, but radiation from flames comes through heating your legs. The brick inside is regular thin firebrick used in most stoves, but across the front is full thickness firebrick to alleviate the heat going forward toward you. The solid firebox door has an inner plate. The intake air comes in the center, and splits inside the door across an opening all across the bottom, and holes at top for secondary air to get to top of fire. So the inner door panel insulated the heat from your legs. That’s why I went with a solid door. Years ago there was thread here with another owner that experienced the same smell I get. Sort of chemical outside, like extremely hot metal, or an engine running hot and lean. Found it was due to near perfect combustion that I believe newer stove owners experience. I think it has to do with the upper air intake causing secondary combustion. I cleaned mid season with a Soot Eater from bottom up and found I didn’t need to. So I burn clean enough to only need cleaning at season end. I keep my pipe damper wide open and have straight up 6 inch insulated Dura-Vent chimney pipe.
Don’t be concerned about reducing to 6 if the one you are looking at is the older 7 inch. Unless you have els and horizontal runs, 6 inch works great for me straight up.
Gaskets on these are flat, folded in the center. There is a slot they push into, so there is no cement used. You can change them hot. Mine is a 2006 (there is a big tag on the back with build date) and still using original gaskets.
The 24 gallon tank heats fine where it sets on a plate around the outlet, and stove top edge. I added angle brackets on the back for extra support and a place to hang utensils. Poker, scraper, whatever. Large Amish families using more hot water connect the coil optional coil in firebox to tank as shown on their website. This makes too much hot water and over humidifies the home for as much hot water as we use. So I never installed the coil for circulation through tank. It is vented to the atmosphere, so you can adjust lids for how much water vapor you want for humidification.
I put it on 2 furniture dollys with back, bricks, and doors removed. I have a handicap ramp on my home since I collect stoves and move heavy stuff here all the time. My trailer tilts, have to keep these on wheels. With 24 gallons added it is pushing 1000 lbs. that is how you can tell how cookstoves are built. Look at the weight.
I remember seeing one for sale about a month ago, stated it had slight warpage on rear. I was thinking of getting it for my log cabin, but I really need the smaller version for under 1000 sf.
