The fire pot is insulated by the hot gas going down around it and the gas is given a temperature bump by the fire pot as it goes by on its way down to the base heating chambers. It is a mutually beneficial arrangement. Pluse there is a lot of radiating surface to put heat out into the room. Plus you get micro control of the fire as well. You have 5 dampers to set to regulate the burn rate. These things have an internal check damper in the bottom of the stove. Besides setting the amount of air you allow in with the primary and secondary dampers, the check damper at the bottom can be set to allow primary air to be directly diverted to the back pipe and out. This action short circuits the primary air path from flowing upward through the grates to directly passing outward into the back pipe. And of course you have the standard pipe damper over all to control the flow rate. You can operate these stoves at very low firing rates and still maintain a high combustion efficiency at the same time.
Sounds like it's going to really be some fun getting to know the newest member of your family of stoves William. I too, am looking forward to getting the skinny on my Herald. She'll be a "Star" no doubt! (pun intended). As I mentioned over on the other thread, I've been using a powerful flashlight in the dark down from the top. This allows me to pinpoint any light leaks with finger of cement at the ready.
I do feel that it's quite airtight now although, I wish the shaker fork was a bit longer. The original was 14" and change but broken. The replacement grate is perfect but the fork is only 10 1/2 inches long. Pulling it out to clear the shelf/lip above gets close to begining to dump the fire. It will possible to use as is, but with care. I'm really thinking that I may have to order another grate/fork set up from Woodsmanspartsplus which has a proper sized round grate with 14 1/2" fork. This is ideal but it's also $169. Ordering just the fork is not an option either as it's wider in this grouping (than my grate's slots).
Another possibility is to send it to the foundrey and see if they can copy it, but lengthen by 4" or so? I'm certain that a "one off" from the foundrey will surely cost more than a new grate and fork. What a quandary!
