Default Aeroil indirect heater

When I first started working on the school build, I wanted an indirect fired heater.

I am not a fan of torpedo heaters or any heater that dumps the fuel/fumes out the end of it into the heated area.

I can't stand the smell.. 35 years ago I worked nights at a SAAB repair shop rebuilding transmissions and such. An the owner used diesel in the parts cleaner as well as a torpedo heater..

After that it ruined this for me.

So I looked for indirect fired heaters but they were all 1500 and up even for a used unit and frankly could not see spending that money..

I had a oil furnace I paid 400 for so converted it to an indirect fired heater but making a fuel cell for it and mounting the furnace ontop of the cell.


Last year a guy listed one of the heaters for sale (free) in CT..

So I went and scooped it up.. It was non working but figured out it needed a new transformer..

I found what I was looking for and installed it..

I fired up the heater but it was sooooooo smokey.. I then tried a smaller nozzle at .65 gallon with .75 angle..

I can not find any owners manual for this heater.. So having to guess at the correct settings.

It's a 300K btu model so the ideal nozzle would have to jive with that.



But, even with the .75 nozzle it was super smokey..

Pressue is dead nuts on at 150psi...

I believe the correct nozzle is a 1.25 or 1.50 with a solid shape spray to get to the 300K btu..


I don't mind underfiring it to just pump out a cleaner burn..

Anyhow because it's a piece of history I decided to pull it all apart derust it as best I can and to shoot it was new paint.

The unit overall seems to have little use on it.. but it does live outside so would like to arrest the abuse and keep it around longer.

I've added a photo of the portable indirect heater I made.. It worked great..

Would keep the building 60F..

I then used it to heat the blacksmithing trailer once the Yukon furnace with used oil burner was installed.

But with getting the real indirect heater I tore it down and stripped off all the parts.. The fuel cell is now used for used oil storage and transfer.

So have all the pieces painted.

The color combination is going to be so funky..

While i matched the colors from untouched areas I'm not sure it's exact..

I tried to match them up but maybe the monitor or online vs in person color stuff..

Anyhow, I also ordered 2 new nozzles.. A .60gph 60B and a .60gph 60ES

Figuring out what is the correct nozzle is the first corrective step I'd guess..

Have fuel, spark but smokey stack.. So that tells me the fire does not have enough O2 or 2 much fuel, or it's hitting the side walls and not burning..

The burn chamber is and plenty long enough..

This is not a retention head burner.. It's the older style..

I already have plans if I can't make this burn clean..

I'll install the Beckett burner out of my old IFH and do an upgrade to the whole thing..

I'd rather get it to work properly as made though so will invest the time and little money.

just sort of curious what the round hole in the exchanger tube just past the fan is for, is there a cover missing? that hole would really mess up the fan air flow unless there is something that I am not seeing

Yes, indeed.. There something you are not seeing.. LOL..

There is a cover for the service access hole.. You can see the greenish panel hanging down on the side in this first photo.

Metal screw at the bottom and thumb screw at the top..

When the unit is assembled that access hole is the way the burner nozzle assembly (nozzle, electrodes, cleaning/adjustment) is accessed and serviced.

I didn't think something like that would sneak by you, I suppose the cover should have been obvious, like it is now,

You never know.. It's a great suggestion that it was missing..

With a product like this and new to oil fired burners anything is possible.

Pointing it out is the right thing to do..


Frankly when I fired it up, I was surprised how smokey it was.. My home made IDH had no smoke after it was tuned and it really worked a treat..


So, I'm using that as the principle on how this should work.

The New nozzles came in, .60gph with 60 extra solid. and the .60gph with 45 solid..

I had read in my "Tech oil burner manual" that to dial in the burner with an unknown burner firing rate,

An 80gph with 60 and 80 degree and a .60gph with 60 and 80 degree should be tested to see which does what.


I'd love to find a chart that shows the spray patterns for 0.45 to 1.25gph with different patterns of extra solid, solid, hollow..

That would be great..

In the manual, it talked about air patterns (its the air pattern that creates the right degree for the nozzle) burner chamber design as the main for which nozzle should be used.

I have a lanair waste oil furnace. I'm not certain it will be used to heat the polebarn, but its lookin like it. I need to get the building up to figure out what goes where and all that good stuff.

So, the heater is nearly complete..

It's all together and just needs a little more wiring put back together.

She is looking pretty good.

I hope she choochs along now after the clean up. Certainly would save me a lot of redesign work..
