Scott,
I am so glad you started this thread. I was getting sick of reading my own posts!
It will be great to see that stoker running full throttle heating that nice greenhouse.
Traffic is finally starting to pick up around hear.

Truthfully this one has me worried Don. It has a stoker in it that will push 40 pounds per hour. I don't see the heat transfer area that there should be. I have an EFM 900 sitting on it's side right next to the garage and the surface transfer area is monstrous. The GJ's might be the fastest heating appliance hands down because they got an over sized stoker in every model. It only has an 8" flue. Here are a couple pictures of the inside of the fire chamber. There are eight tubes. Two rows of four. Sorry for the pictures. It is hard to get an angle that shows all of them at once.

That sir, is bordering on blasphemy and is punishable by the immediate surrender of your coal burning privileges. Please see the bailiff ....Salemcoal wrote:You've almost inspired me to slap one of the smaller GJs in my garage in place of the efm

X2. I don't see where they are inferior. They are a stout underfeed boiler without all the drama that the EFM's have.

Well, theirs only one way to find out how much coal it will use. Fire it up for a season.Scottscoaled wrote:Truthfully this one has me worried Don.

That's interesting, yours has round tubes like a Losch. How many baffles does it have?
It sure is hard to take good pictures inside a boiler, isn't it!

It's Ok Waldo! The drama I'm talking about is all the moving pieces. GJ's are so simple. There is a motor, transmission, blower and auger. Not many pieces other than that. They are hooked together without connecting rods, oil baths, clickers, clutches, pot bushings, all the other moving parts. That is the "drama" I mean.

No hanging baffle. Just a water wall at the back of burn chamber.

I always liked the simplicity of the GJ stoker, a motor turns a blower and a pulley. The pulley turns a belt that turns the pulley on the gearbox. The gearbox turns the auger. It don't get any simpler than that!
For those of you that don't know, the old GJ's were built with very high quality/heavy duty parts. The feed pipes were made of brass or bronze. The augers were made of a special stainless steel alloy. The rings in the pot are designed to rotate the combustion air to promote spiral flow. When they put one of these together they wanted it to go for at least 30 years before anything wore out. Pretty difficult to find anything like that today.
