Inspected by a Tech? More like a back yard automechanic doing his first job! icon_rolleyes.gif


Yepper, all the parts seem to be there

BTW,


The holes in the vent connector in my other post were this boiler!

I will post the photos of the masonry chimney for this one in the exterior section.

Looks like an old Federal or Gibraltar boiler, steel boiler with a wet leg return, (wet base steel boiler). Age is about 45 years old. I would recommend replacement because it has past it’s life. Depending on the burner, it still could have good efficiency. Draft regulator is broken and has to be replaced, flue pipe needs to be sealed to chimney base. Someone removed the boiler jacket. There is two things that OK with the heating system; (1) the pressure is adequate for a single story house (2) the circulator has been replaced with a one piece unit.

This particular boiler serviced a two storey 2000’ square residence.


It had baseboard rads (longest runs I have ever seen!) with a lot of dirty and damaged fins.

One inch pipe runs served the rads. Boiler fired up well, ran quietly, and each rad tested (even the furthest run) threw a good amount of heat.

According to the model and serial number on it, it is 21 years old. The burner assembly had been replaced in 1999.

Who manufactured the boiler?

American Standards Products Steel Boiler.


And going back through my notes, the age came from a local companies tech. Model #324 Serial # 418.

In my opinion the boiler would not be operating anywhere near peak efficiency. Not without the jacket and given the general overall condition of the boiler and venting system.


The barometric damper is poorly located and clearly spilling combustion gasses into the home judging by the corrosion inside the swing area of the damper and the corrosion of theciderblock below the barometric damper...

The boiler itself is clearly heavily corroded and has had high temperature silicone applied to seal some major leakage areas.

If the burner has been maintained in the same poor shape, it will be suffering severe drop in efficiency. For the home described I would guess the boiler is also over sized...

I would replace the garbage with a semi-sealed mid efficiency boiler in the 84% efficiency range, but not a condensing oil boiler..

a new boiler would have a different venting system... necessaitating sealing off the existing chimney inlet.

John -


You've mentioned the word "Oil" in reference to heating on several of your posts. In 25 years of inspecting in the midwest & Texas I've never seen oil used for heating anything. Is this something you see up there.

I've heard it smells nasty - don't they have gas??

Hi Dan,


Yep we have gas.... tons of it by comparison to other regions... however infrastructure is a big issue here and I am in the most populous region of Canada, Ontario.

Here in Toronto oil used to be a dominent player in the home heating market. Gas is now the leader having displaced oil most homes but their is still a core following demanding oil since they cannot afford to pay for the conversion to gas. Mostly the remaining oil customers are oil using large oil fired boilers made from cast iron. We just happen to have a large practice in hydronic heating and deal with oil frequently.

However, in rural areas of Canada oil is the dominent heating since gas lines are sparse in smaller communities and more limied to the larger rural centers.

Electric and oil heating used to be fairly even but electric is pricing itself out of the market. Air source heat pumps have all but been totally abandoned here due to the prolonged sub zero temperatures that make air source heat pumps inefficient to operate.

Ground source heat pumps are making inroads into the markets here in rural areas though.

Of course we have our share of propane heating too, as well as some trying a blend of active and passive solar techniques, super insulated houses and "off-grid" housing with wind power and a blend of technologies. I have designed more than a few systems where the clients needed super efficient heating systems.

Oil however was what I first had the most experience with as a fuel source, especially boilers. Since then it has been slowly dying out to be replaced in all urban centers with gas. only the rural cottages and summer homes have oil now with regularity... but they are enough here to warrant staying current with the equipment.

oh and yeah it smells nasty, and if you even cause a leak you are in a world of hurt because it absorbs into cinderblock like a sponge and it will never come out.

mechanics love it since it guarantees major service calls ever fall to service and start up their customers equipment and tune the burners...

Oh also if you ever take a trip up this way I could make up for all those years you have never seen the fuel oil in use... there are still tens of thousands of oil boilers and furnaces in Toronto. I didnt want to give the impression they are rare.
