Thanks Greg. Yeah I am pulling "cold" basement air in through the blowers. The basement air is probably 10 degrees warmer than the rest of the house! I agree though that it would be much more efficient by ducting in the cold air return. If I go that far, I might as well increase the size of the hot air ducts as well and throw a larger CFM blower in the furnace. My dilemma is how much money do I spend on modifying this furnace to possibly make it work ok?

I do have to say though this furnace is definitely putting out some heat. It is also putting a ton of heat out the chimney. I am getting a good 12 hours between shake downs and re-fills so that is good. With the DIF mounted to the ash door, I can recover a low coal bed fire pretty easily. I am going through around 125 -140 lbs of nut coal a day. In the next few days it is supposed to warm up so it should be a lot better.

I am leaning towards a stoker for more of a "set it and forget it" type of operation. hmmmm...more research and reading is required! LOL

Well I went out and got a new digital thermostat and a couple Rutland magnetic stove thermometers. I was thinking my furnace was pushing too much heat out the flue pipes. Here is what I found. Current idling temps are: 380 in the flue before the baro., 150 on the flue pipe and 200 on the front of the furnace about 2" above the feed door. DIF is off and house is 71. I will post back later tonight when the furnace is back firing what my temps are. I am very surprised by the temps shown with the Rutlands. I would have thought they were much higher. Maybe this furnace is working about right after all! Maybe spending a few hundred on making the return and heat ducts more efficient is all I need to do! :beer:

You maybe right. The temperature readings sound good. The return cut in from the first floor and the larger supply maybe all that is needed. Your furnace sounds like it has the potential to give you the heat. Now all you have to do is direct the heat flow in the right direction. :idea: :)

Updated temps as she is firing nice right now. Flue probe is 770. Flue pipe is about 300. Front of furnace is just shy of 475. I did almost lose it this morning though. I was a little lax in my shakedown last night and only did a couple light ones as my dad was visiting. This morning there was not much heat and I got 3 full trays of ash and even pulled up a few decent sized clinkers. :o She is burning good now though!

Here are the measuring points:

Looks like some more heat is to be directed into the house. You have her burning well. Keep it up. Now think how you can get all that heat upstairs. :idea: :)

Just want to update. I only burned the coal for 1 week and went through 750 lbs. The temps were only cold for the first 4 days and it was pretty warm the last few days...warm enough the fire eventually went out due to not loading it up full. I feel that is a LOT of coal to use in a week especially when it wasn't as cold as it had been a good portion of the winter. At that rate I feel I would use well over 6 tons and it just isn't economically feasible for next year. That would cost me over $1500 unless I wanted to make a couple trips into PA to haul my own. We will eventually switch to a stoker as I like the coal heat but don't like the extra mess involved with shaking this thing 2 times a day. I am also very concerned with the grates themselves as they have been replaced and this is the 3rd new set. Luckily the first replacement set was warrantied. These are a very weak design. I placed my order for a load of logs to be delivered soon and will get it cut, split and stacked asap. It will be a lot more labor intensive. There is also another reason for the decision...I won't have to put anything on the credit card this way. :)

I will be looking at getting better air flow through the furnace to make it more efficient. There are lots of great tips and ideas on this so that will help. I will post updated pics as I progress over the summer and into fall when we start burning wood again. Thanks for all the help and awesome tips!
