With malice towards none, I have been doing actual remunerative w-o-r-k for a couple days.
I remain a skeptic based on efficiency testing, but am keeping an open mind.
two different posts...
I thought I read here that most of the Ashford's heat comes from the stove top by the cat and not the sides. Is that so? If so, the cast iron jacket may be more for show than go than on our stove.
This is my fault.
I have pretty good utility usage data. The season I switched from a 2001 non cat to a brand new BK Ashford 30(May 2014), I also had a long haired daughter move out. My data is confounded by the drop in hot water usage, DWH being heated by the oil burning furnace at my house. I can say with utter confidence my wood consumption switching from aged non-cat to new BK was a drop in wood burnt somewhere between 25 and 40%.
House stayed the same temperature.
Heat from the cat, also my fault, expanded below.
I was about to say that.
Everyone’s definition of a burntime is different. Impossible to bring it to a common denominator.
True. An ideal work day burn for me is I get home 1-2 hours before the wife, with enough hot coals to not need kindling, and a still active combustor. There are 37million and six variables. Ideally I will find enough hot coals to make a wad softball to cantaloupe sized, and a still active combustor.
This is one reason why, just figured it out, that i like my fuel at 12-16% MC. If I have an active cat and enough coals I can stuff that thing as full as it will go. With not very many coals I can get my incoming fuel load charred in about 48 seconds because dry wood ignites fast, and with an active cat i can engage promptly. With combustor engaged and the tsat on high I can start ripping BTUs out of the stove into my envelope mui pronto. If I can get the envelope hot enough fast enough, clothing optional.
I am the guy who gets up on the combustor and stays there. I can maintain summer time temps in 1200sqft with an active cat, regardless of burn rate. If the combustor is active and all I have to do is maintain, I am golden.
If the envelope is cold and the cat is inactive I am going to burn an appreciable amount of fuel getting the combustor active before I get serious about heating the envelope.
I don't know what percentage of total BTUs come out of the combustor, but I am working that margin. And with the fans available, good bye snow pants.
It is my observation that in bypass heating the combustor I am wasting a bunch of perfectly good fuel heating up a combustor that was probably hot enough to be active just a couple hours ago. Turn the Tstat down a notch, keep the combustor hot, have the house warm when the wife gets home.
