Wolf and Seasoned Oak;
We have a summer grate for the Kitchen Queen that adds little to no heat to the inside of house all summer.
In the morning we get eggs and the meat ready, usually scrapple, and remove lid over firebox. Dump a small waste basket of paper/ cardboard through the top. Add a few small pieces of kindling and open chimney vent that allows heat directly up chimney. Have the pan ready and light the fire on the raised grate. As it flames, the pan is the lid directly over flames. We like the non-stick aluminum flat griddle by All-Clad. Be ready to add food and keep it moving because it cooks fast. We set a Chinese type tea pot on top for 2 cups and when done leave chimney vent open and open air intake fully. This type cooking is faster than any electric stove top and hotter than a residential gas stove top burner. We have a commercial Garland gas range with star burners that burns twice as hot as a residential range and it is about as quick cooking on either here. We prefer wood for the stove top and only use gas in the summer for oven.*** If you open kitchen windows when cooler outside than inside, as the chimney cools, the draft through open intake (or firebox door) continues to draw outdoor air into the house until draft stops. This takes more heat out of the house than the cooking created.*** This is the same principal as using a fireplace to COOL a space. Open windows and burn paper/ cardboard to heat chimney. The rising hot gasses create enough low pressure in the house to allow more cooler outdoor air in than the heat that radiates inside.
I don't see how you could possibly do all that without removable lids. A wok also fits into the hole over firebox for stir fry. I'd estimate between 50,000 and 70,000 BTU wok burner, and I'm a retired gas man that maintains a Chinese Buffet so I'm familiar with setting up their jet wok burners from 80 to 100,000 BTU.
Our Queen is very easy to control as well, and I thought there would be a learning curve to cook and bake, but it was very easily learned. I added a thermostat as well on the back years ago which is the same design as used on the Heco today.

Look familiar? I designed it after having a talk with Duane the KQ builder. It has been in use for quite some time in the Amish community.
The Queen has the same air vents on the sides for circulation that work well, and we prefer a solid door over glass due to running much cooler. The Queen has a inner baffle plate on inside of door so the incoming air keeps the door cool. You can stand in front of it without roasting your legs. I don't see how you could stand in front of a glass door canning for hours. Adding glass doors to a stove that was purpose built takes away from the original purpose. They were not built to look pretty, much of the Amish religion being "plain" and a more complex term, the rejection of hochmut or not being prideful of oneself or the things we are a steward of while we are here. So the local Bishop agrees with ministers of an area, which products their church district will allow. (such as all the same color silo, buggy, or clothes) This alleviates all competition between anyone having anything "better" than the other, so the appliance that gets the vote is the one approved for the church body to use. When an Englisher (non Amish) makes a suggestion to an Amish company to make changes or do something for looks, there is a lot more to making a change than it appears. A glass door for instance is deemed to be useful to see the fire. If it wasn't for practical purposes, it would be voted down, and you would never see the change. So if you want Amish quality, you will end up with a utilitarian design with nothing fancy.
More info for the original poster asking about area heating; We have the 25 gallon stainless water heating tank on the back and it is advisable NOT to install the stainless water coil in firebox to help heat the water tank. It simply makes too much hot water causing steam and the vented cistern creates too much water vapor in the home. The water tank heats plenty using the edge of stove top where mounted. This is built for Amish use where it is the only water heating source where much more hot water is used. You can then use the firebox coil for a hot water holding tank with circulating system for radiant or baseboard heat in the farthest rooms from the stove. If you have a second floor, you don't need a circulator pump to move it. Be careful with how much baseboard or you will extract too much heat and be into a creosote forming scenario.
