Currently burning a Harman magnafire mark II coal stove... Spiral flame... problem is the spiral flame is now part of the glass door. Tried everything to clean the glass but nothing seems to work. Any suggestions?

Our Earthstove used to have a glass door. Was always hard to see thru, it got broke one night when I dropped a log on it, so I ended up welding a piece of plate steel on the inside of the door. Any pics. Sounds like an interesting unit.

My in-laws use easy-off oven cleaner on their wood burner glass door panel a couple times a year. Works fine.

Mornin Mark,
Harman is the TOP of the line, very nice stoves !!!

If you have any wood ashes around, dampen some newspaper and dip into the ashes and then on a cool glass door try polishing the glass with the damp newspaper coated with ashes.

We use a cleaner for the glass stove stop burners. Works real well and it does not take much to clean the glass. Any appliance store including the big box stores should sell the stuff.

Later,
Dab

I own a Mark III, and have not attempted to clean the glass,
as I replaced mine in November when an errant ball found
it and it shattered. (stove was not burning)

etc.. I'm sure you can search and find your answer

Harman are made not that far from where I live and they are good units. I sold the Alaska stoker coal stoves and wood stoves for six years. The glass on the stokers was always difficult to keep clean but the oven cleaner is a good idea. We sold a product made especially for the glass, I'll check in the garage and try and find the name.

Yep, oven cleaner works great. I have a Harmon Mark II and it also works great. I also have a AHS Multifuel boiler in my garage ( coal/wood/oil) to heat the whole house. I burn mostly coal in it and it is an awesome and very efficient unit.

I am also a member of the coal forum Dutch mentioned. if you ever have a coal stove question/issue, they are all very knowledgeable over there and very nice people.

Thanks for the replys and links. It should warm up later this week and I will let the stove burn out and try oven cleaner. Oven is self cleaning so I will have to go buy some... thought I had a can in the camper but didn't.

Where can you buy a stove like that ? How much ? And where do ya get the coal at.

We have an old Home Stead wood stove , it's about 20 years old.
The company went by - by.....

The old stove has seen it's better days.

I bought it used, one year old. $1600 stove for $700 with the optional hot water coil (not using). Coal is now $192 per ton so I don't burn unless it is really cold outside. 72,000 BTU's of pure heat. Burning coal is a lot different than wood. Cleaner but a lot more ash to deal with.

Most folks who burn coal in this area use the stokers. They are self feeding and use rice coal. There was a day when rice coal could be bought for $15 a ton because nobody used it, now it's close to $200 a ton. Coal is harder to start, I think the ignition temp for coal is around 900 degrees but once you get it going it produces a good steady heat. The stokers can be as small as 30,000 btu units and will go 60 hours before refilling the hoppers. I am using a 144,000 btu hotwater stoker that is heating a big old stone house and does a decent job. Seventeen years of constant running without one problem so it has been dependable.

Once I get the firebox heated to about 250 degrees using wood scraps, I can get hard nut coal to ignite. Stove pipe temp runs 300 - 500 degree range.

I just got a price from a store about 2 hrs from our home...
They said they could get 1 sent to our home for around , ( you better be setting down )....... $ 2700.00........... Is this right ??? , it must be one really good stove.

I found some coal on a pallet at my local Tractor Supply, last year for about $ 275.00 Ton.....

I like the idea of not having to build a fire every day with wood, and the coal stove burns up to 6 or 8 days, Self feed,

Corn is out of the question, it's around $11.50 a 100#, and on the rise..

We burned over 3 cords of wood so far,this year, we may have an early spring, the trees are starting to bud out.

I like that stove , BUT....... $2700.00.....??????? OUCH >>>>>>>>

Mine is not high tech... I use a shovel to load and shake the grates by hand... $2700 is probably about right for a self feed hopper rice coal burner.

Killer,
what kind of temps do you want to run the stove in?
do you get and stay below freezing?
I know with my hand fired stove, when the temps
stay above 40, it's time to shut down, as I can't
really run my stove too low. I know it's different
with a stoker that has electronic controls.
You said they have a pallet of coal, would more
be readily available down the road?
