Be very careful Dan, you never know how closely you are being followed. When Goggle Earth snaps a shot of your property and identifies YOU as the one taking a leak on the back 40, you will know Big Brother is waaaaaaayyyyyyyy to close for comfort. Can you hear that drone I dispatched to your house yet? Put that away.......
Keystoker handfeds perform very well and are extremely durable.
When the power is out, no one bitches about hand feds........of where there is NO power, no generators.......wait, not many moving parts. If you die before a shakedown and refill was due.......well you get 'cold' faster than the stoker guy who waits until the ashes plug it up or the supply exhausts itself.
Just two days ago, I fired up a Tarm 202 to heat a building 40 by 60 with 27' ceilings and a 7" thick radiant slab (2 PM first fire) . Slab temp was 27 degrees at all corners and at 8 pm it was 40 degrees. You can do the math....7" thick slab, antifreeze in the piping(obviously). Next morning 52 in the building, slab and air temp inside. Outside was 12 degrees. Last night it was 59 degrees at 8:30 or 20:30 for us military folks. This AM at 08:00 it is 70 in the building, top to bottom. Feed water at 115 degrees, return at 72. Total coal used (stove, nut and pea mix) 320 lbs to achieve this temp. A little high, and dialing back to a 65 stable temp.
Taco 1"mixing valve was by-passed until temp of building stabilized. full blending of feed and return resulted in a 10 degree differential overnight. I questioned if the Tarm had enough output, but like they say: slow and steady wind the race every single time. 78,000 gross overcoming that demand was fine. Where did I 'assist the process'? Draft inducer was mounted inside the building.....thereby adding a draft enhancement. Stack temps leaving the boiler at 450, and after the inducer 185, and 130 at exit.
