Following that's do as I do not as I say it's helped me beyond, I apply when you speak i listen
Do as I do not as I say, that's example
I believe in having a CO tester. A few years back I upgraded my low cost tester that functions just fine, to a Testo 317-3. Having two devices confirms the accuracy of my Testo for occasional checks.
Mike teaching a customer was always my of my favorite things to do, made the Job go faster and you made a friend and customer for life.
I told my father about your situation he is also an HVAC engineer and before that he was an HVA sales he sold those boilers all the time and with the age of that boiler the reason why the external or the exhaust temperature is so high is because it's a good possibility you need to drain the boiler and clean out the passageways in which the water flows because over time those corrode rust up and constrict constricting the water flow hence reducing the heat transfer it's probably calcium up and calcium does not conduct heat that's why you're losing it out the trim chimney pipe so he could make that boiler last another 30 years those things are built like a tank and if you really wanted to replace it you can buy the exact same unit today built the same way you don't have to buy no condensing boiler and put in $1,000 worth of storage tanks to keep the 180° temperature cuz you're going to have to install a storage tank a highly insulated storage tank that heats up the water temperature to 180° and get that circulating through the house
So, do the passageways get replaced or cleaned or boiler blown out with high pressure water? You said you can still buy that same exact boiler?
20:01 we dont like those when they go bad. Especially in the winter right? Mikey Pipes I am learning a lot from this channel man. A whole lot.
"Unless there's a problem, I wouldn't touch anything." You, sir, are the real deal 🏆
Mike, you’re a good boss as your employees are your number one asset
As it’s the same in reverse.
Mike thanks for all the knowledge that you give to us. You’re an excellent boiler technician.
I just came upon your channel and having been in the heating industry for quite a while back in the 70s in the 80s, we delt always in oil and sold weil McLain exclusively I found your discussion quite interesting. My current boiler is a P4 66 which is probably about 45 years old oil fired. Running well, does not leak any water even in the summer when I shut it down. It has a tankless coil which I no longer use so it’s been disconnected. I found your discussion on heat very interesting. Thank you very much.

Glad I could help! I have a lot more to teach, so keep watching.
He seemed like a nice gentleman, your explanation was worthwhile in this case, I believe he learned something from the extra time you spent talking. Amazing how inefficient the older equipment was. All that expensive energy wasted just going up the chimney.
Nice break. Very cool of you to take call. Your techs appreciated that four days. Right before crazy season.
I remember I messed with a pressure relieve valve on a water heater when I was starting out and it wouldn’t stop leaking water. One of our companies plumbers came out and tapped it real hard with a pipe wrench to stop it. He said never touch those. 😂
When having three wires under a wire nut it is standard practice to twist the wires together with a plier before putting on a wire nut. Failing to do so can cause a wire to pop put from under the nut. In this case that wire would not get pulled by itself through the connection point. Someone worked on it in the past and did not put the neutral back on. The loose neutral was likely making loose ground against the side of the box making intermittent ground and causing intermittent operation.
I hope the customer appreciates your knowledge, good spirit and patience.
I hope so!
The mechanical engineer thought he could impress Pipes with his knowledge. It didn't take long for Pipes to turn the tables. 😂👍
Humans are never to old to learn 👍👍👍👍👍
engineers are always the best
Now that’s a professional 👍🏻💯
Thank you very much for the support and comment. Remember if you live in the Long Island New York City metropolitan area I need a plumber for a heating repair. Give us a call at 516-348-6300.
FROM CHICAGO IM YOUR #1 FOLLOING YOUR VIDEOS EXELENT JOB I REALY LIKE YOUR WORK GODBLESS YOU
Awesome! Thank you!
Informative video 👍. Nice customer.
Thanks 👍
Oh man, I absolutely do not miss doing the service calls with the “engineer”, self proclaimed beings who hold the threads of the universe together. Going into Lyophilization field service was the best decision I’ve ever made 😅. Bless you, Mike.
Nice video. Thank you for sharing. Have a nice Thanksgiving weekend
I learned from Eugene as well. He’s the best.
Mikey !!!!!! you are the best. Wich company and owner does that for their employees??????GOD BLESS.
Fantastic video Mikey! 👍👍
Thank you! 👍
I had this same boiler! Replaced the expansion tank a few years ago and computer board ($245). I bought the part and hired a contractor to replace for $90. The igniter was replaced twice in the last 15 years. The first time it went out it cost me $550 to replace by a HVAC ripoff company. It failed a year later. I found the part for $25 on Alpine HVAC online and bought the parts and fixed it myself. It cost me just $35 for the part. It worked ever since. The installer either installed a faulty one or it was a cheap component.
My HSI controller doesn't last more than 2-3 years. I think the back wall of the enclosure gets too hot for them. Best luck with honeywell S8910U
Mike: GREAT INFO!
:)
Didnt know that cast iron boilers could condensate exhaust gasses if the return temps are too low (moving the exhaust gas condensation closer to the boiler) and that exhaust gasses do condensate in the chimney liner if the gasses cool down enough.
Thank you for teaching us!
yes, water return temps of anything below 140F are very bad and the moisture from the gas and air burning will cause condensation between sections where the flue gas is, as well as the flue piping above and the chimney too! bad news times three.
That is correct
@@PipeDoctor I have a weil-mclain VHE series and it has pretty much self destructed because of rusting out heat exchanger. I have limped along by using a flue brush so the pressure switch proves. I realized the 140F conundrum while looking for a boiler replacement and looking at W-M GV90+ series. I have to respect the durability and serviceability of the brand despite my experience and I believe cast iron is still a better choice than SS i.e tankless. Don't these high efficiency cast iron boilers have a secondary heat exchanger to isolate the condensation so it can be carried away and maintain non-condensing temperatures in the cast iron section? Also I have ductwork and air handler so one thought is to put a heat exchanger in the plenum to even get enough heat extracted and get the return water down to the dew point. Otherwise it seems you would have paid for the high efficiency capabilities but never get the return water cool enough to get the rated performance. Great video.
I'm an engineer by profession, Mikey rolls eyes
I think when he moved the door the neutral was moving and hitting some metal in the box and grounding out and that’s why it worked sometimes?
The history of slotted screws on wooden ships largely ties back to the ancient development of the screw itself, with the earliest known use of screws being in wooden constructions like water pumps attributed to the Greek mathematician Archimedes, who lived around the 3rd century BC Rybczynski found mention of the slotted screw in a technological treatise from 1588, in a book on metallurgy from 1556, and depicted on a pair of manacles in an illustration from the late 1400s. Slotted screws also held together guns and kept armor from shaking apart as early as the 1480s
Great service, great customer interaction. I’m gonna guess 5-6 Benjamins. Well worth it. Am I in the neighborhood? I don’t live in New York
I love Wago connectors.
me too!!!
So true about everything you said
For the combustion analyzer, don't you need to have the covers placed to get normal operation readings? since you mentioned that the system is engineered to have the openings a certain way.
So you don't recommend a condensing boiler when the house is all baseboard in a cold region? Great video
That is correct
that stack temp is high for oil as well, typically 350-450 for most units 20 yrs old or less
Feeding the peoples Mikey Pipes. #LoveBosch
Nice job 😮
Thanks 😅
I bet the neutral wire (white) from the tranformer was grounding out on the inside of the 4 square and finding its return path back on the equipment ground (Green/ bare) wire.
My diagnosis also
You’re the man!!!
Our HVAC techs in Midwest don’t interface with customers like this. I wish we had Mikey Pipes in the Midwest!
Had same boiler too, was hugely over sized for the house though
13:51 so it's basically a 150 amp circuit breaker but just on neutral 😂
check gas pressure,replace relief and extrol tank/feed valve....add stack damper above diverter and wham....she's brandy new with free heat...sure you could go for spark ignition but...
thats the way to save him money-winner winner ..turkey dinner
Ditch the plug in relay it’s only necessary for 1 zone boiler not necessary with separate switching relay , r and y become t-t
Best to have a yearly maintenance tune-up.
Holy shit, that boiler was installed in 1980? We only have furnaces where i live and they only last 10-15 years tops.
Please tell me that you didn’t charge this old guy to connect a common wire that came loose. A first year could have figured it out and fixed it in 5 mins.
Customers don’t realize that their constant running-the-mouth INTERFERES with any HVAC tech while he is TRYING to analyze the situation and determine what the problem is and what the cause of the problem might be.
Motormouths slow down the repair time and increase the bill!
Love to see the Wago’s👍
Moving the door may have caused the neutral to “ground out” providing a return path and allowing the system to run…. Just a thought.
that's exactly what was happening. the end of the wire was stripped back and was probably hitting the 1900 box creating a neutral.
LILCO... That brings me back
Silberstein taught me too, everything I know, you went to SCCC?
Evenings and weekend for 2 years just for his class
Ooo 30 minutes Letts gooo💪🏻 just drank 2 long Island teas feeling great🥃 18:17 praise Eugene silberstein🥃
You got this!
That neutral was probably hanging lose for a long time, and just touching the metal junction box, and effectively feeding back through the grounding on the boiler instead of back through neutral. But yeah wiggling it would have moved it around the box causing it to make better or worse contact.
That's a good explanation.
Why didn’t you turn down the burner so the stack temp was within range and would give a better efficiency rating
I have a mental picture of a helicopter with the engineer inside the cockpit!
Haha, I can just imagine the engineer swooping in with a cape and a wrench, ready to save the day! Maybe we should start a superhero plumber series!
Selling it to him without selling it to him ..
Love it
Mike, I have a friend who is an engineer for Boeing for the past 25 years. I asked him WHY things are designed to make it difficult to repair. His answer ? "Because we can !"
Because management's bonus only depends on keeping the build cost low.
That's funny mechanical engineers are the best they got a piece of paper that says hey I got money I'm stupid lol I got to call the other day from a potential client says his water heater wasn't working I asked her if there's gas or electric he said he didn't know but yet he was a mechanical engineer
44 years ... he got his money's worth for sure
Absolutely it was a good guy
does it fire
I see a fan relay and a 40VA transformer.
If an Oil Furnace tech shows up in something that looks like a repurposed Bread Delivery Truck, then you know they are qualified.
Those used FedEx trucks are fleet vehicles that are not made all that well. They're designed to last five years.
Check gas pressure. Maybe little high.
so what can you do to bring down that stack temp. into low 400f
how that ran without the neutral wire connected prior to the service call is the true mystery great video mike happy thanksgiving
it was either slightly in the wire nut just touching or it was touching the metal box and returning back through grounded boiler case/piping.
in that case, if the boiler ground is poor everything connected could become live at 120v.
We got a talker momma
This is got to be one of my top three service calls so far for this heating season. Absolutely love this guy.
why is there two t-states
You're tester is measuring combustion eff correct not afue eff so I'm not sure I agree with your reasoning of stack waste being the difference of your combustion eff.explane that to me
How do you know if someone is an engineer?
They will tell you at least twice!
Haha, great guys though
better question is how did the neutral wire disconnect itself? lol
what you all staving fro
Heating customers in New England sure like to involve themselves
water is hot all perches must be Sealed
If I am paying by the minute, I don’t talk.
Don’t worry, buddy. I love you anyway.
I like , Dont do your best, do my best
dig it
line and load
Lilco?! 😂 that's not an old service record at all
Right? It’s like finding a vintage record that’s only a few years old-still a classic in the making!
I love working on holidays etc - no traffic - meter monkeys not there typically cheers
Plus all the money goes to the boss man. You wonder why I leave by example? I’m as hungry as they come.
My hero
I’m far from a hero, but thank you
caps and barrels
You’re not running service calls yourself. You have us
You're right!
water is hot all perches must be Sealed it’s a losing battle
There was no Output adjustment screw on the Gas Valve ?
Mike, could you replace W-McLaine EG-75 in Greensboro NC?
Sure he can. For 27k
A tad more likely
smartest thing you use is WAGO....German
It's not 110V, if it's that low you have problems 125V nominal is now standard
heat at 56?!.... thats around 14 celcius... that's ice cold in a house
air separators
water
I have seen this before!!!🙄 white neutral wire hooked around the screw and then the fan center tighten down on the wire using the unit ground wire, which is technically grounded to the neutral bus bar at the panel box with that fan center being loose, taking the cover on and off with vibrate the fan center and allow the neutral wire to make continuity on the screw Bet you $100 that’s the way it was set up originally because I’ve seen it two times in my lifetime… stupid wrong idiot, but I’ve seen it done likewise on metal EMT. I’ve seen guys take their ground off of the conduit. 🙄🤦♂️ But man that stack temp??🔥🔥
somebody made a bad connection many years ago, go figure! probably didn't "lead" the stranded wire ahead of the solid wires when putting wire nut on, if you don't it ends up pushed or or hardly connected. the yellow wire from relay is capped, because it's connected to the incoming hot(common) of the normally closed(NC) terminal and it will be live via the relay when relay is off.
unless they wired normally open (N.O.) as the line and relay common as the load, but even then, ALWAYS cap off all unused wires!
Ah, the age-old battle between solid and stranded wires! If only they had consulted the wire gods before diving in!
The only good condensing boiler is the GV90 series Weil Mc Lain . Forget the wall hung boilers that need too much maintenance and expensive parts that most contractors do not carry on their trucks. The heat exchangers on cast iron boilers will outlast any wall hung boiler by 4 times. The money you save in fuel, you more than pay back in repairs. I been in the industry 40 years and people want reliability, not your parts are back ordered see you in a week.
Same question I asked Mike above (GV90+). How do they get the return water cool enough to condense the flue gasses? Seems condensing boilers need radiant in order to get enough heat extracted to even condense. I'm looking to replace boiler with baseboard radiators.
How do you shut this customer up! Stop talking
Sounds like Archie bunker
air will not pass air
How come u never go in with your tools?
I generally approach the service call to assess and diagnosed using my brain and my hands before I bring any tools into the home. The reason for that is that my clients are paying for a trip charge and initial diagnosis on an agreed-upon price before they schedule the service call. Once I arrive and assess the situation, I tell them what our services will be to continue and if need be, I get my tools.
This is how successful professionals operate
And I am far from successful
I am learning every day
While I attempt to make the trades great again
He wants a new boiler. Sell it
Go to basics , no power low voltage and high voltage
