Anyone burning wood in a Hitzer Ez-Flow 50-93?

PostBy: JohnB On: Sat Jul 06, 2013 6:28 pm

Since this is my first post I'd like to say hello & thank everyone for all the great info on this forum. After burning wood as our primary heat source in a 250 year old Colonial for close to 30 years I'm ready to buy my first coal burning stove. I'll be replacing a Jotul 600 & after looking at MANY different coal stoves, Stoker & Manual, I'm pretty much set on the Hitzer 50-93. Got a good look inside one today & it looks like if I pull out the removable lower hopper section I should be able to burn wood in the early Fall & Spring months. With no top baffle plate it won't be a particularly efficient wood burner but I'll only need to take the chill off the house when it's not cold enough to burn coal. Any owners running their EZ-Flows this way? Any reason that it might not be a good idea?

Yep, if you remove the boot you should be good for some small fires--don't go pyro-nutzoid--I'd bet you could learn to get that 50-93 to idle at real low temps--lotsa help on here my friend. Welcome to the FORUM & you're making a real good choice with the 50-93.

Hi John, welcome. Like Fred said, you might be shocked at how low that Hitzer will idle.

The reason I'm considering burning wood Fall & Spring is that I was told that the coal wouldn't burn well in a manual stove until the outside temps dropped below 40-45*F. I have several friends running Harmon Mark 1 & 2 stoves & they tell me the draft isn't good enough to keep the coal going in early Fall/Spring so they run wood fires. Have I got this right?

Maybe yes maybe no , it all depends on how well your chimney drafts in warmer temps . I can't burn coal during the really warm weather but have no problem during the shoulder months like Oct. and up to 1st part of April , while others can burn all year for their dhw etc. , so each case is a little different .

John,

I don't think a good installation has a problem with draft at any time. As hcarlow pointed out, there are folk running their fires year round for domestic hot water. I run my old stove during the shoulder months including days when the outside temps are in the 70's and sometimes higher while the night time temps are still dropping down to where some heat is needed. My particular stove needs a bit more draft (I feel) than most modern stoves so if it works during those times, any good installation of a modern stove shouldn't have any problem...

just my 2 cents worth...

I'll be running the Hitzer into the same 6" stainless chimney liner I use for the Jotul. The draft is ok at best. Our house is halway up a large hill out in the country surrounded by tall trees. Even a slight creosote build up in the liner has a noticeable effect on the draft. The smoke doesn't rise straight up from the chimney outlet more then a couple feet before it either drifts sideways well below the tree tops or rolls down the roof from the chimney edge.

It would be nice if I can get a few coal fires going before it gets really cold as I'll need the practice. After decades of living in a toasty warm house my wife won't be very happy if she comes home to a cold house & a husband cursing the new coal stove.

A couple of (possibly dumb) questions for those familiar with the EZ-Flow models. If you are just planning on taking the chill off using a coal fire do you just add small amounts of coal as needed as opposed to filling the hopper? If the hopper is filled & the fire goes out can you make enough room to build a small wood fire to get things going again without coal pouring in from the hopper or would the hopper have to be emptied?

john i have the Hitzer hand fired an honestly burn coal in 70 degree weather .Get a flue an stove thermometer.I have had stove at 160 dr degrees an flue at 150 using nut pea mix in late October .Did wood 20 years.Try pea in fall an keep a diary on outside an house stove temps .Check old post here in archives reguarding burning in warm temps .Forget wood . jackGood luck

John,

I don't run the stove you are looking at, but in the stove I do run the answer is no. When running at low temperatures (stove temperatures, not outside temperatures) I still run the stove full of coal. I just run down the air feeds and close the damper. I don't know if the Hitzer is one of those stoves that doesn't use a damper, if that is the case, then you just close up the air feeds. With my old stove, it can be tricky to get it to run consistently below 150 but I have been able to do it. My flue temps are running between 50 and 75 at that time. But for you with the Hitzer, it will be a lot easier to run it low I'd imagine. Careful with the temperatures being quoted, they are very dependent upon where they are taken on the stove. The thermometers used are usually surface mounted. What they read depends upon exactly where they are placed and the stove they are on. So exact numbers between stoves is hard to compare.

It might not hurt to make your chimney a little taller to get a better draft too. Theres a lot of info on this site about chimneys. Coal doesnt draft as good as wood because the chimney doesnt get as warm. I dont have trouble with my draft but my Dad does. Eliminate as many elbows and T's as you can as it makes a big difference in draft too. Just my 2 cents.

If you get a used 50-93 hitzer, make sure it has a removeable hopper if you plan on burning wood in it. The older ones werent removeable.

On my Jotul wood stoves the thermometer is placed a couple inches in from the front or rear corner. Is that pretty much where you read the stove temp on the coal stoves? How far back or up from the stove is the flue thermometer normally placed?

This is the original chimney on our center chimney colonial so it's coming right out at the peak of the main house. I doubt adding some height would change much in this situation & it's not really an option I'd consider at this point. The stainless liner is a straight shot up from behind the stove so only one 90* connection. At least it's an inside chimney & it's capped so it should hold the heat well.

The Hitzer I'm looking at is new but last winters stock. A local dealer has a very good price on it which also includes the optional blower. The lower section of the hopper is removable which differs from the 30-95 I looked at where the entire hopper lifted out.

I reload it (I have a hand fed furnace) the same whether its 50 degrees outside or 10 degrees outside. Heat output is based on combustion air input. A coal fire can be idled way back during the warm part of the day (in shoulder months) and then cranked up at night when its colder. Maintaining an adequate draft in the chimney is more the challenge in times of warm weather burning. A coal fire is much more efficient with less heat going up the chimney to keep the draft.

It doesn't really matter. The thermometer is used for your own information as you use the stove in order to control it better and/or have an idea of how the stove is running. Stove geometries vary. My flue exits from the middle of the back of my stove, not the case for the Jotul. In my set-up, my flue runs straight out he back for a few feet where it meets a tee with the chimney. Likely not what you are doing either. The shape of my stove is totally different from the Jotul. I've placed my stove thermometer in agreement with another member on this forum that runs the identical stove as mine so we can swap numbers. The placement was selected for easy viewing. They won't directly relate to what you read on your stove, at least not in absolute numbers. You can get an idea of the temperature ratios between stove and flue. The actual temps are specific to your stove, set-up and how you need to run your stove. It's nothing to worry about at this point, you'll figure it out as you run your stove. The temps are more like seat of the pants indicators. Now, if you are running your stove and the flue temp is 400 - something needs to be changed, for example...
