New here. Harman super mag

PostBy: Mackman On: Wed Jan 11, 2017 6:00 pm

Hey guys. New user here and also new to coal. I used to be a pellet burner. I just got the stove yesterday. What a difference in heat output compared to the pellet. Thing is a beast. I uploaded a few photos. I got the brushed nickel trim kit. Dealer didn't have it do it is on order. Gotta say thanks to this page. I almost got another pellet stove. But i been reading everything on here for a week. You guys made my decision. No way i will ever go back to pellets.

Congratulations and welcome to the forum!
I've had a few people mention they were thinking about a pellet stove, when I suggest a coal stove they look at me like I have 3 eyes!
You may need to add a barometric damper to the smoke pipe, coal stoves need to have a regulated amount of draft. Depends on how the chimney drafts. Too much draft to the stove and heat and $$$ are going up the chimney.

Welcome aboard the coal train partner. I, like you, considered another pellet stove before discovering coal. I almost resorted to burning wood too lol. Thank god that didn't happen!

You'll love coal, more heat for less money. Wood pellets only have 2/3s the btu's as coal per weight.

I store the coal for the hand-fed Harman outside the back door. The stove is a few feet from the door, short trip to get coal. Sometimes I forget to cover the supply and it gets wet. Try that with pellets.

Requiring a warm and humidity controlled building to store your pellet fuel isn't exactly a "win" in my book ;)

Your installation looks great! Always glad to see someone enjoying the beauty of coal heat! Welcome to the board :cheers:

I have a heat pump. Im thinking of tieing this stove into the cold air return. Question i have is. Will that hot air hurt my air handler? Still amazed at this stove and coal power in general. My neighbor stop over today. I told him i replaced my pellet with coal. He looked at me like i was crazy. He came in a checked the stove out. He liked it. Coal is awesome. How have I not realized coal stoves till 2 weeks ago.

Congratulations, I tell everyone coal is like pellets on steroids! I would of had a Magnum if it wasn't for dealers that just didn't get I was buying :mad: I ended up with a Keystoker and am very happy.
A guy I work with was using Propane, and I was amazed at the monthly checks he was writing, he relized the madness, and after a holiday weekend, showed me his latest purchase a used Harman Mag. He said "it was the best thing he ever did". That system paid for itself in the first year!

I am venting the top of my stove to a blower that pumps to the upstairs and there are no issues with handling the air, it is not a central heat blower but behaves as one, controlled by the thermostat on that floor, works great.

Welcome to the forum Mackman. That is a real nice looking set up you have there. There is a little bit of a BTU difference between your old pellet burner and the super mag! ;) Quite a few here have made the switch and commented about why they didn't find coal sooner.

A few have tied into the returns of their air duct and some have tied into the supply run too. The specifics of your set up will determine what is necessary to optimize it. I tried connecting to my return and supply but didn't get any better performance than leaving it unconnected and directed at the stairway in the basement and having a cold air return in the far bedroom. But we have a rancher so it is only one floor above the stoker we are heating. A friend has a two story and needed to connect his mag stoker to the ducting to get the best heat distribution.

Except for the ash volume I could never understand how any pellet stoves get sold in NEPA given the cost savings of coal there and the vast heat output difference.

Welcome to the Forum! Yes, the Harman will work well without a Barometric Damper but it will work even better with it.

I didn't find the Forum for a couple of years after I got my stove and didn't have a clue how to burn coal. I was keeping journals in the early years and the savings in coal and time before and after Baro is significant. A properly set Baro will even out the burn, reduce the amount of coal burned and lengthen the burn time between tending.

I actually have two Harmans, a MK II and a MK I. The Mark I does not have a Baro due to the fact there is no room on the black pipe for it. The stove partially sits in the firebox of my chimney. I have to do all kinds of manipulations with the fire to control the draft, i.e close the air valve almost shut, allow the ash to build up so it blocks the draft and use pea coal to block the air channels. But ... because the air valve is almost closed and the ash is thick I could lose the fire in a heart beat. Or... the draft could kick up and cause the stove to overfire rather quickly. I spend a lot time checking on this stove.

A baro would eliminate all that attention; I wish one would fit on my MK I. Take care, Lisa

A baro is needed to set draft. You can over fire the stove and burn the grates out from what I've read... Also Harman has spec's to set the draft. A baro will do that.. without proper specs' the stove can push exhust gasses back into the house as well and or will let the heat go right out of the chimney.

As a fellow Super Mag guy myself welcome... I have been burning Coal since 1981... hand fired stove's until this Super Mag about 4 seasons ago. Wish I had it many years ago.. but I was young and didn't mind all the issues with hand fired...and bought them because they didn't have any moving part or electrical items to worry about. With that said I've had no issues in these years with the mag except my grates recently that I probably loosened while pokeing about during cleaning. They are only $40 a piece so no big deal. And it works hard being I have a large home and temps frequently get below zero F and reach as low as 40 below.
