Working On A German Buderus Boiler
HTML-код
- Опубликовано: 7 дек 2019
- I am maintaining the Buderus Wall Hung Boiler. Buderus a hi-efficient German boiler This is labor-intensive maintenance. Therefore I take the burner section apart. Then clean out the burners, drain pan, flame sensor, trap, and exhaust. Next, I test the boiler. Afterward, I did a combustion test yet due to video length I didn't include that. Buderus Boilers require yearly service I found out this boiler wasn't serviced last year. Buderus Boilers keep an HVAC tech busy.

Nice to see a thorough cleaning from start to finish. Definitely not easy. You made me realize I should order a set of gaskets.
My one suggestion is to wrap the bottom of the boiler in a garbage bag during the cleaning to keep those little granules out of the electronics and plastic gears used in the slide-out control panel.
The best Hacker in the world is at it again repairing another broken boiler. The knowledge he has emanates from his brain! How can any one person be so smart, only God knows!! People also know him as Mr. Clean because of his outstanding cleaning skills .. He out shines them all. To be the man , you have to beat the man, aka The Hacker. Woooooo !!
I agree with dry cleaning of exchanger. Tip: 28:36 First I put a thin cut to size board in the baffle slot. This prevents the dirt from the top falling through into the lower fin tubes. As a brush I use a cut off part of a street broom with longer bristles to crush the dirt small. followed by BLOWING WITH VACUUM HOSE in the air outlet of a big shop vacuum. This gives more volume power than nitrogen bottle and is cheaper. Visa versa for bottom section. Tip: put condensate trap on cover before mounting them together.
Q. What is the purpose of the oil in the trap? Prevent evaporation?
Not many service companies work as thorough as you do. Complements.
Man I'm glad you made this video. I repaired one of these last week and had never even seen one before lol. I got it running but now I know how to clean it.
One of the cleanest Buderus GB142 HXs I have "ever" seen. Most are caked up with the white mineral deposits.
I love how you stuffed the camera into the heat exchanger when the helicopter popped in haha
Uninstall intake and top burner, cover flange rod and igniter, soak exchanger in mineral oil, reinstall top burner and intake. Set on high fire for 10 to 15 minutes. Open both top and bottom plate and you’ll see that the collector plate will be so much easier to clean along with the exchanger. I use a small bottle pressure washer to rinse the exchanger after the bake. Glad to see you did a really thorough job on this German beauty though.
This makes oil service look easy.
Thanks for the vids bro. I like to see what other trades are like. I feel like if I was that worried about the plastic tank breaking I would just order one
The customer doesn’t want to spend money on stuff sitting around yet has no choice for the gaskets, clamps, ignitor, and flame sensor. I don’t work on that buderus boiler often. From my watching my video I believe it would be easier to put the trap in place and then install the bottom of the boiler right unit the neck of the trap. They don’t become brittle if primed with mineral oil. Interesting how I can learn watching myself work.
Thanks dude! I just watched this video and I was able to do a nice maintenance on a 90% Buderus. The one I pulled apart was filled with way more sediment lol
It’s one of the reasons I share my work. Sharing knowledge and experience can help anyone that wants to watch
Love this relaxing video! And, I don,t even have a boiler!!
Good maintenance vid Bill ...
Nice job
Seems like any savings gained in efficiency of Buderus condensed boiler is eaten up in costs in yearly, in depth maintenance vs conventional Buderus boiler. Where the condensed boiler appears to be strictly yearly the conventional Buderus can go two years without adverse conditions being created. My guess is those gaskets will cost a pretty penny. I have not seen a condense boiler clean out so Thank you, Sir, well done
I know you said that you were supposed to use mineral oil to clean boilers but you mentioned 2 other products some type of oil and then simple green. What kind of oil was it you said? and what type of simple green? Was it just regular all-purpose simple green or a specific kind?
That is the most over engineered german thing I have ever seen! I mean it looks like a high quality unit but I can only imagine how expensive it must be!
Make sure when installing the ceramic burners to place metal tag over the ignitor and flame sensor or you could have intermittent flame failures!
I was working on one. CO error. Turns out the I need to either clean or replace water pressure switch .
It is a dutch boiler! It is a german compagnie but the original disign is Dutch!
Admittedly, I skimmed the video I didn't notice you addressing the "6A" error or the flashing red light on the UBA 3. Did I miss it?
My boiler shut down yesterday, No Hot Water. There is power going to the unit but the control panel will not light up. Any suggestions. Also have a problem finding a qualified Buderus Tech to service, any suggestion? My original guy left the area.
this looks a bit different to my 1979 coal hand fired Buderus boiler that has heated this house in the cold part of the season for the last 40 years.
These are insane how much work they need for a cleaning 2-3 hours might as well have a cast iron on the floor… any money you are saving on gas is going right to maintenance and repairs
I totally agreed you my family owns a oil company and I'm a plumber and I'd rather work on an oil boiler
Great Stuff. I got a GB142 leaking in the front where extrusion meets the side cast part- both sides. Mostly when its real hot like 180. At 140, it drips slowly. I had to place plastic on the electronics and blower to keep it going. Otherwise the unit would shut off throwing a Blower code. Is it the trap plugged or am I in more trouble? I'd dive in today but its 20 degrees out. Local P&H companies just want to replace it without even opening her up. YIKES.
your heat exchanger is bad. it is leaking from the sides? If under warranty (10yrs afaik) you can try to file a warranty claim, but they will be demanding regarding proof. water samples, etc. Replace heat exchanger is the only realistic fix if it is leaking at the seals on the sides of the exchanger where the bolts go through. hope that helps, sorry for your plight if I'm accurate.
I ended up opening it up and cleaning out the particles- that slowed the demise. After it was replaced by a IBC, I took it apart and saw how the pipes connected to the side manifolds were leaking. Pipes were ok, so was the side manifold. Weak spot was the connection/glue. So sad to throw that sweet unit out out just for that. Thanks again for showing how easy it was to take it apart, that helped me dare to do it.
@@steveluhr3889 glad you're running. I'm not the video author. Did they replace whole boiler or just exchanger?
Whole boiler. Went with IBC SFC 125. Simple, efficient. I didn’t want to deal with it again in 10 years.
What type of chemical are you using to clean the bottom cover?
Nice. What solution did you use to clean the parts ?
Manual says 50/50 mineral oil/ water.
Have you ever tried wet cleaning leaving the bottom plate on, spraying with diluted coil cleaner rinsing it either water through the condensate trap?
Also I’ve been told that you must use rhogaurd glycol in these but this one looks like it’s attached to a straight water supply how do the exchangers hold up without glycol.
Manual says spray with 50/50? mineral oil (Health section of the local grocery store) and water mix. Kind of works, slowly.
Changed out several of those,those aluminum heat exchangers don't hold up.
All that piping is like a Picasso
good video bro ,but the only thing is that the ionisation elektrode (flame sensor) is all most gone and it needs to be changed even the rubber gas-kit of the burner too each time you maintain this kind of boilers.
The customer is ordering new gaskets, ignitor, and flame sensor, I can get a few years out of the gaskets. Yet turns out i haven't serviced this boiler in 2 years. I doubt whoever serviced it last year did much more than watch it run
These boilers chew through flame sensors for some reason
After watching all the way through I gotta wonder, does the fuel savings from the extra efficiency get eaten up by the extra long tune up.
there is a 80% boiler on the other side of the house. The gas bill even with the high efficient boiler is around $700 a month. it would most likely go 1-1100 a month. Maintenance on this system cost $400. Thats one month savings summer time it may only cost 1-200 to create the hot water.
The HVAC Hacker yikes. Is this a very large home? Any idea on the square footage?
Is that crud from the gas ? Not seen that much residue in our natural gas here in Australia .
Minerals in the water or steam?
By product of the aluminum heat exchanger and combustion. You get less of it with a stainless steel HX
Buderus recommends the use of mineral oil to clean the heat exchanger, fire it off then rinse down with water. A real pain in the butt! Oh and just a hint, if you try to spray the mineral oil from a spray bottle you're going to have to warm it up to lower the viscosity or even he best pump spray won't handle it.
That’s good info. Does the mineral oil break up the crusted white stuff?
@@thehvachacker somewhat , but won't replace periodic consistent maintenance.
For what purpose is the Oil in the Trap?
Prevents the plastic from drying out and becoming brittle
Like every other buderus Gb 142 already has the Customer # on the panel ......
What's the lichid from 9:40 ?
Why dont you get an air compressor for the van or a second bottle of nitrogen
GB142 TOP
I love German design.
you don't see them as often as you used to because everyone got rid of them...
labor intensive without a doubt. but performance when serviced yearly no problems. other than factory out bound manifold which leaks like a son a bitch. was a recall. which they did a piss poor campaign to inform users and owners they damn well knew were owners. it was kept as close to vest as possible to avoid costs. but that breakdown is epic as these boilers are very reliable if certain maintenance is completed. kudos for documenting it. there are no systems in your home that do not need attention on at minimum yearly basis. i completly forgot about the logamax myself. after seeing this last year,,,,, oops after opening her up. far worse. but not significant damage. lots of scraping, not brush work. but if you dont take care of things nothing will last and people assume in general, after i buy something new,,, its fine, its the best you can get, it will run forever..... i dont need to do anything. it has the best energy star rating and warranty there ever was.
for the cost of this boiler and the reluctance of US companys to get on board leads me to believe, with any downfalls that this product will outlast most others by far.
amazed that common maintenance has been pushed aside, with no responsibility of what you purchased for your home. and that it may require some attention that you need to get off your ass to keep running properly.
More like performing preventive maintenance...
That’s what I’m doing
You left a clip off carbon monoxide death for sure
I already returned with new clip. That one broke during the maintenance.
A lot of pipes lol
Yes radiant heat. Each pipe eventually connects to a pump and a manifold with flow control adjusters. In order to equally distribute heat to the floors. It’s a half a day maintenance yet really should be 8 hours. The boiler alone took me three hours to service
He didn't even check the gas connection with soap and water and you didn't even Purge the water out of the system put new water in in Purge the zones what the heck
What a joke, she requires a team of NASA engineers to maintain and keep her running.
a joke? it doesn't look any different than cleaning any other type of condensing boiler. in fact it looks easier because of the disconnect on the gas valve...
So let me guess - Being German made its twice as complicated, twice as expensive, and half as reliable. Lol -Just like there junk ass cars.
It’s a good boiler yet not the easiest to service
They are better than naviens thats for sure
That boiler is trash.
