i have been reading threads today about fresh air intakes . I was looking for ideas on how to hook one up to my hitzer 82ul . sounds like it will help pull less cold air into the house and became more efficient .

Interesting block work. I'm curious as to how much heat you get upstairs with your set up. Nice work though and unique idea. :idea:

i just kind of threw it together . I just stuff the gaps with fiber glass insulation . it took a couple different setups but I ended up with probably the simplest you could use . duct to the closest register with an 8" inline fan . register happens to be in foyer . in cold weather I run the stove between 350-375 and burn 60-70 pounds of coal a day it keeps first floor at 68-70 and second floor 70-72 . not to bad for a 200 plus year old house with somewhat insulated walls single pain windows with storms and plastic wrap on the inside . the plastic on the windows makes all the difference in the world .

That may work if it is close enough. I don't think it has to be on tight. I remember a pic (I think) where someone with a stoker did that, just laid a pipe in from a window, I think they said it worked pretty well. The stoker that hitzer makes has an optional outdoor air kit. Call them they are nice people to deal with maybe they can explain this kit and if something like this would work on a hand fed. Just a thought keep us updated if you call them.
Have a great day, Eric

talked to dean at hitzer today . he thought with the drafty basement fresh air may not make much difference but I should try a MPD to make it more efficient . told him I go threw 60-70 lbs a day thought I could do better MPD should help .

Do you have any type of damper now be it Manual or a baro? If not more than likely you are using a lot of heat up the chimney

Did you set the baro up with a manometer? I to am running a MPD and Baro, started this at the end of last season. Don't know if I will stick with it but I am going to this year. I did notice more heat from the stove when I had the MPD closed, so I think it is worth a shot, I know I will continue experimenting this season.
Best of luck, Eric

mason coal burner, your setup is very similar to mine. I have a sheet metal cabinet I built around mine with an 8" round duct and a fan blowing the HOT air into my kitchen vent. I pretty much heat the whole house this way. It is amazing on how well this works. I put a fan pulling cold air from a cold spot in the house and blow it into the basement. This keeps the warm air moving around and distrubutes the heat by moving the cold air and creating a vaccuum. I used 2 six inch fans at different spots in house and just cut them into the cold air return ducts for the furnace. One is placed at the bottom of the steps and give the cold air from the second floor someplace to go, and the other place is on the first floor across the house from the stove.

last year was my first year burning coal . I went the first couple of months setting the baro by pipe temperature I guess . then I used a manometer from the loaner program . had a problem at first only had .01-.02 draft . hose on manometer was loose . fixed that then checked had .05-.06 draft . when stove is going you can really hear the suction . no matter what I did to the baro I coundn't change the draft . dean said for ever lbs of coal you burn its about 14,000 BTU's you have to try and keep as much of that heat from going up the chimney as possible . he said with a strong draft use a MPD to try and retain as much heat as possible . he said they have had an 82 going in the warehouse for the last 18 years and they only run a MPD . there draft is so strong they keep it closed all the way . sharkman8810 I stole the duct off the top to nearest register from you and tried to mimic FA with block cabinet . I tried other setups . this one worked best . simple is better . I do heat my 2700 sqft 1780's drafty house with just this stove . sometimes I need a small wood fire in living room off the back of the house . stove works great . my 2nd floor is warmer than 1st because register with heat is in the foyer .the only time I even turned on the oil furnace is when I went away for christmas . I will be hooking up a cool air return to existing duct work . then play with fresh air . nothing to fancy . thanks for the help .

Use a baro and MPD, buy a manometer off ebay and mount it. I think they can be had for a real reasonable price. Then just experiment how far you can keep the damper closed. I could keep mine closed all the way, we will see how it goes this year. Like I said before I did notice a differance with the MPD.
Good luck, and have a good weekend, Eric

I use a baro damper on mine, and it works good. My chimney is pretty tall. I just adjust the baro by feel, but I should probably use a manometer. I've noticed that covering a baro can help when you want to waken up a fire to increase the draft, or if it is in the warmer season and the drafts decrease and you have the temp swings of 50's in the daytime and 30's at night, and your fire doesn't want to kick up to get a new batch of coal lit. I'm glad that setup was able to provide some inspiration. I wouldn't have thought of using block, but the insurance people probably really like it, and it would be good for tight clearance situations.
