This is one of those jobs that is right up there with drain cleaning on my list of "bummer jobs" but hey, its gotta be done by somebody!

Good cleanup job! I doubt burner coil stays on continuously becomes its not necessary. I'd think it would wear out the coil pretty quickly if it did. Usually the control box turns off the igniter after a delay and a flame sensor then monitors the burner.
I have that same vacuum and it saved my home. Three years ago my basement flooded in the middle of a frigid Maine winter. Couldn’t get anyone to come fix the issue for six weeks. That vacuum ran sucking up water - no joke - 24 hours a day for over a week. Still sucks. Very well.
one dam good vacuum
You’re better off with a sump pump or transfer pump for something like that
Thank you very much for the video! Unfortunately my boiler wasn't as easily accessible, but still managed to get access to the heat exchanger without too much hassle. Wish I would have used gloves when disassembling everything. I'll definitely wear some while cleaning out the actual HE.
Got quoted 1700 for someome to come out and clean the that exhaust vent and heat exchanger. After watching this, I think I might tackle this myself.
😅
That unit is sooting up because of incomplete combustion. You either have too much fuel or not enough air. A blue flame would not have that problem.
have you ever open the heat exchanger cast iron and clean the inside water limescale or dirty stuff there? if so how do you make sure the exchanger sealed back so no leaks?
If it was a new install, would you be allowed to have the oil line where it could be stepped on or tripped over? Considering the price of oil, it might be reasonable to upgrade to a modern high efficiency unit.
It would be preferable to have the fuel line in the floor, not running across the top like that, but I don't think there are any restrictions on that specially. I think an upgrade would be a very good idea.
@@ReubenSahlstrom Couldn’t the fuel line be protected by some 1x1s attached to the floor? That would be my solution to prevent future damage to the fuel line.
When the furnace is ultimately replaced, that ought to be part of the project.
I live in Maine and our oil lines are required to be encased in a plastic housing. It’s also very common to slope mortar along each side of the copper line to make a sort of on/off ramp.
Hello Reuben,
in the heater room has always small open window for fresh air for heating system…regards from north Germany
that's old skool. I got a Lochinvar Knight, that's old in itself, lol
You just saved this guy 35% on his heading bill... EASILY..
Whats the purpose of the flapper on the exhaust to chimney?
It's called a barometric damper, and it helps maintain a draft in the chimney flue. As far as I understand, if pressure builds up in the chimney exhaust it closes off, and if there is a healthy draft it lets a little air in to maintain the draft. It has a weight that can be adjusted to some degree, to get consistent operation. It also increases efficiency by allowing heat to stay in the heat exchanger and not get pulled out by a draft from the chimney prematurely.
@@ReubenSahlstrom I see now, It keeps too much draft from pulling too much air thru xchanger hurting efficiency. Too much draft can be caused by several things including a tall chimney, very cold outside temps. Excessive draft also can cause the burner to overfire. If the gas pressure regulator is set for a certain pressure, the high draft can actually pull more gas through the regulator, overfiring the boiler. Also, there is a double action damper that actual lets flue gasses enter boiler room if chimney is blocked, it has a spill switch that shuts off flame if that flue pressure is high.
@@publicmail2 Neat! It's pretty amazing how many simple devices are still used today, and work so well.
If it was not oil fired you would not have to clean it-right!
The oil is a little dirtier, but the gas ones do the same thing at the 25-30 year mark.
Did I see a hole punched in the flu??
I think that there was a hole added there to conduct combustion analysis testing and then it was filled with something. It was added before I worked on the unit.
