Yes I have some efficiancy problems, (other than spelling efficiancy).
Pipes now have some insulation on them, boiler skin temp is about 40 F, based on infrared thermometer.
Clinkers are about toster size in volume and cresent moon shaped.
I can list some obvoius problems if you would like.
I seam to have a coal addiction, and no woman, these issues could be related.
Dwelling is 12' by 16', whole shack is a 12' by 32' wharehouse from the railroad circa 1945, 4 by 4 studs every four feet, four layers of shiplap with tar paper for insulation, I've added some foam board under the sheet rock.
Picture window is two single pane windows stoped into the framing, you remember the wavy glass that makes things move and wiggle as you move your head, not to mention one of the outside panes is broken.
When you hear a gust of wind outside you feel coolness on your face.
I have 6' of baseboard in the crawlspace to keep the plumbing working.
I have a zone that sends hot water out to 300' of pex around my septic tank, under the four inches of urathane foam, same zone sends water to 300' of pex that is on each leg of my drain field, under 6" fo styrafoam and two feet of dirt, these zones have not been needed this winter yet, last winter they were heated from a heat exchanger from a side arm hot water tank on my coal cook stove, I sure like not lighting that stove this winter.
I have about 30' of baseboard inside this shack and it just stays warm
My goal is to just feed the coal to it and get to spring. First winter here didn't have any water, and this shed was on blocks with just 3" of wood between my bed and the outside, sheets would freeze down to the floor with the frost from my breath, now it's on a foundation, and I have a toilet, and cental heat, I'm moving up.
Attched are some pictures of the side arm from the cooking range and the heat exchanger to allow for glycol in the field and septic circuts, installed last winter, to get the toilet working.
