ahhhh...ye olde puff back! :shock:

this happens when you smother the flames with the fines and new coal, volatiles get heated up and come out of the new coal (especially quickly with the fines) and they then get ignited when a flame appears!!


Yeah, it always makes my kids amazed with it does that :)


Also.. does anyone on here use a battery backup for their stoker? I'm trying to figure out what my best option is for a backup. I'm going to keep my current Mark II and use it in a dire emergency, but I have a generator and want to battery backup my new one.

I don't - I just wheel the gen set out and fire it up when the time comes. I'm usually home all the time, so that's not a problem.

I was just thinking that you may need to tweak your air circulation and experiment a little to get the heat from the stoker upstairs effectively.

You will need a path for the cooler air to return to the stove, not just heat registers for the warm air to rise. maybe an open door to the basement will allow cooler air to fall down the steps, maybe you will need a floor register with flex duct that runs to the basement floor....Can't tell from this distance! :)

I don't have a battery backup for my stoker. I have a generator. If we lose power I have about an hour before the stoker would go out. If the power will be out for days I have the Mark III waiting in the corner ready to be called into action.

Not long after I installed the boiler, I had a power outage of a couple hours. Was pleasantly surprised when the fire lasted just shy of an hour without going out. Gave me plenty of time to wake up and get the gen going.

Well I'm kind of doing it backwards.. I have a log home with an open floor plan and a loft.. the radiant heat from my Mark II heats my entire main floor and upstairs perfectly.. as I never have the blower on ever. What I"m doing is running a 6" pipe into the floor below the furnace to push hot air down into the basement. I know most advise that this is stupid because heat rises, but I will never need the blower to heat the upstairs and my basement stays 60-63 degrees with no heat.. and it's not super huge, so pumping that blower heat from a vent in the ceiling should heat my basement just fine. And I don't wanna sound dumb, but how would a stoker still burn for an hour without power? My friend has one, and as soon as you pull power it goes from bright red to out in 10 minutes. Am I missing something? Esp since I will have the vertiflo system.. it's not like extra coal will gravity feed down. And I have a generator myself, but sometimes our power only goes out for 1-2 hours tops, and I don't wanna have to drag out the gen in the middle of the night if I don't have to.

Might just be the way mine is designed - it stays bright red for over 10 minutes after the blower and stoker kicks off. Probably has an easy path to the draft. I can definitely feel the cool air constantly being pulled through the combustion blower when it's not running.

ahhh... i misunderstood, i thought the stoker was going into the basement...my bad.

If the super mag is the same as my old style mag stoker you will get loads of radiant heat off the unit to heat the area where it is.

You are correct, no new coal gets to the grates. The coal on the grates stays lit (at a low level) for that long because the established draft through it keeps pulling air even though the combustion fan is off. I don't know if that is because I have outside air piped to the fan housing or not.

That's good to know. We barely ever lose power for longer than 10 mintues to 2 hours.. and if it's longer, I have the generator running anyways. So if I can get a battery backup to run for at least 2 hours, I would be golden.
