Welcome to the FORUM my friend. What I would do first is to get a wire brush & go over the whole stove & get at the obvious slop on it--around the doors,the doors, etc. Anything that looks like it will come off without smacking it w/ a hammer & chisel--that may come later. Have you ever used the stove or was she just stored?? I'm sure you will get alot of suggestions so be patient. Again, welcome to the FORUM. Remember, the only stupid questions are the ones we don't ask ;)

Welcome to the forums!! It's slow right now, but it'll be picking up very, very soon as people hop back on from the summer and get ready for the winter fun time.

That looks like a very small stove. How hot does the smoke pipe get? How long can you hold your hand on it?

From the picture it looks like there is very little heat absorbing surface. I don't think you will gain much adding a baffle.

More pictures and how much house are you heating?

that is originally a coal fired designed iron boiler, upgraded with an oil burner and a combustion chamber. It will never be efficient by today's standard of almost $4 oil. too much mass to heat up not enough surface area. at .75 firing rate, pretty small already. Seal up the doors and anywhere else you can, where air leaks in, more expensive to operate. Use Kaowool strips or furnace cement available at heating supply . Aero burner is made in Canada, not the most efficient around, but not bad . run as little excess air, and high c02 without making smoke.

I have the same boiler, mine's a 400, which has one more section than yours. Great coal boiler, but terrible oil boiler. I've seen the oil converted ones run with everything from homemade baffles to the custom oil baffle's from Shafter Brothers in Montreal. They all have one thing in common, they burn copious amounts of oil. The only way to make it run efficiently would be to convert it back to coal, the fuel it was designed to burn. I heat 2000 sq ft with a Viking Junior 400 using cast iron rads and fed by a Will-Burt 30 stoker, and couldn't be happier with it's performance.

I bet it is. It was never designed to be fired on oil. Sadly there isn't much you can do to improve the efficiency. One of the old tricks is to put bricks in the large passages to help improve efficiency...and that trick has already been done. Keep the heat exchanger clean, and start saving for a different boiler.
