I've bought a Jotul 507 new in 1980. I mostly burned coke in and it's was unbelievable. The heat that radiated from the coke fire alone kept a 2 story house toasty as as long as the outside temp was above around 20 degrees. Below 20 the oil furnace would kick in but oil consumption when the coke was burning was minimal. I also had a Right Way wood stove in the basement, shrouded and tied into the cold air return) I would fire up to keep the oil furnace from starting.
After the initial fire up and the coke was burning and desired drafts were set the stove burnt so efficiently that you could actually hold your hand on the flew pipe. The stove it's self was way to hot to touch and you could be on the other side of the room and feel the heat radiate(15-18 feet away). There were ceiling fans in most rooms in the house, 2 on the living room, where the stove was, and 1 in the kitchen. The dining room did not have a fan but the circulation kept it just fine. The stairs going up went to a foyer on the second floor and ceiling fans in the 4 bedrooms kept the entire second floor comfortable. Sometimes we would have to open a window.
The coke burned so clean just an orange glow and a blue flame flickering across the top and smokeless. The best size coke chunks to start with were around baseball size. I would pack the firebox with paper. On top of the paper I would add wood. I would cut my kindling wood in 4 in lengths and split it up in finger size pieces. I would put these pieces in on top of the paper vertically, one layer, then fill the stove to the top with coke. Then close the ash pan and top doors. With the firebox door open light the paper. The paper would burn catching the wood on fire the wood would burn starting the coke as it burned the coke would fall down to the brick lined fire box. Adjust the draft and sit back and enjoy the heat.
In the morning just adding a few small chunks of wood to the fire before putting on more coke and you were back in business. If you didn't add the wood and just put on the coke the fire would die. When the coke went out it would be cool enough to handle in just minutes. It was bit amazing that it could be so hot one minute as go cold that fast. When this happened it was back to square one. Clean out the stove and start over.
I always kept the ash pan cleaned out and the ash never built up to the grates. I burned this stove for 10 years and the grate and brick, except for 1 cracked brick, are still in like new condition.
I also kept a large teapot on top of the stove to keep the humidity in the house. There was always hot water for tea.
