We just moved into a new home which has a Biasi 3wood5 in tandem with a conventional oil boiler heating system. I am looking to burn anthracite coal but all I have to work with is the instruction book that came with the stove. I really need some help to pull this off.
From what I have read on the internet, it seems that it is not necessary to have the grates to burn coal. Is this correct?
If so, how much coal do (can) you load in (before it starts to fall out of the door)?
Do you bank it up to the rear/sides of the stove?
Any support would be greatly appreciated.
You can burn without the grates but it is more difficult without. I burned 200lbs without the grates and although they are not great they do help. The grates have a high front so you can pile alot in. My biasi orignally came without the grates, there is a knockout in the side of the stove and the metal cabinate so they can be added. If you decide not to use the grates i would reccomend a piece of threaded rod and maybe a second bent in the shape of an L so you can go between the built in grates. Either way you will get about 50lbs or so in before it runs over. My boiler is hooked up in parallel with my oil boiler, I could have it set so my oil boiler comes on when low on coal but i turn the burner off and just run it on coal. I get about 24 hrs out of a 50lb bag, the temps are in the 20's at night so im not sure what that will be like later since this will be my first season burning coal, i am keeping the house at 74deg. I can tell you its much cheaper than oil. I check it twice a day once at 5 a.m. and again at 5 p.m. open it up shake it down fill it up and a few minutes later close it down again and walk away for 12 more hours. I dont really bank it i just fill it up leave it a little high in the middle and slope it slightly to the front because if i put too much in it will fall out the door. l40knocker helped alot as well as reading some posts in here, I had taken the barometric out and you really do need one. My stack temp runs aroun 75 to 100 deg. closing the built in damper on the back of the stove helps the coal last alot longer. If you have any other questions i will try to help.
