Im looking for a stove to heat our shop 936 sq ft two levels 1,872 total saw a Harman stove lookes like a magna fire sf-250 without the tubes. Any one know any thing about this stove. Our shop is a metal building up top down stairs is all concrete except one wall.

They are great stoves. About 120k BTU if I recall. Is your shop insulated? You'll need alot of BTU's if it's not insulated.

Yes well insulated.

My barn is 36' x 26' x 10' to the loft ... then the loft is another 5' up to the peak .. so I've got quite a bit of cubic feet to heat -- all uninsulated too, with the exception of 2 new doors I put in. My warm air furnace is 100,000 btu, but in order to get it warm enough in there so I can work, I also fire up a 125,000 BTU kerosene heater. Even running both, it takes a good hour to bring the temps from 25° to 55° ..... then I have to leave the kero heater on for another 30 to 60 minutes to make sure all the metal in there is warmed up ..... otherwise, the second I shut the kero off, it'll cool down 10 degrees & the oil furnace will struggle.

Once everything is warm, the furnace will maintain 60°+ out there when it's in the low 20's outside. Any colder & I have to turn the thermostat down to 60° or even 55°, just to give the oil burner a rest. Have to run both at the same time or it will take all day to warm up in there.

I've got a nice mark II for sale. 72,00 BTU's heats 1,900 sq. ft.

I'd buy that in a second if I had insulation!

So this stove is worth looking at for my application ?

What do you mean, it doesn't have the tubes? Did someone cut the tubes off? Sounds unusual. Snap some images and post here. We love picures and you will certainly see more responses. BTW--I have the SF250. It's a fantasic heater.

Yes, photos needed. Maybe Harman made a large stove early on without the heat exchanger tubes?

Yea that's an old boy. Check out the grates and make sure they are not warped. They should be straight and not sag. Make sure they operate when you move the shaker handle.

Will do! Any info on this bad boy from anyone

If I remember correctly that model was the SF-150

The SF150 I've used [belongs to a friend, is in his garage/shop] does have the heat exchanger tubes, just like the SF250. The SF150 is one firebrick narrower, so about 4" narrower than the 250. There used to be a SF350 as well, at least there was literature printed for it.. I don't think anyone on the forum has one.

If the grates rock smoothly, and are not warped, that should be a good stove. It will be a radiant heat only stove, since it doesn't have the tubes, but it will still make a lot of heat.. and if you want you could add heat exchanger tubes and a small ductwork and fan on the back,, and 'almost' have a SF150 or 250.

Let us know what you decide.
