Buderus GB125 in the US?

Joe@buderus_2

This is the first step for introducing the Buderus oil burner. We are already looking into the oil condensing models boilers, but introduction of the burner is the first important step. This burner is MADE BY BUDERUS, many saw them being test fired after assembly on the trips to Germany. This burner has about 15 years of use in Germany so we are confident that it will perform well here in the U.S. Education on it operation and service is important. Lo-nox is becoming more of an issue in residential applications as well.

Buderus GB125 in the US?

Anybody have experience w/ the GB125? I heard it is supposed to be more affordably priced than the G105, G115, and G125.

the GB125 is a blue flame oil boiler, it is currently available to certified contractors only. 89% efficient on #2 fuel oil

G125

BUderus is offering the G125BE oil fired boiler. This is basically the Buderus G115 model with the Buderus lo-nox (blue flame) burner. The burner is made by Buderus. The system is sold as a package, boiler, burner, R2107 control and tiger loop set up. The G125BE series boiler is only available to contractors who have attended a training class, pass a test and certified by Buderus to install these units. The training is being done mostly by Charlie Smith. Please contact our training department for further details. The GB125 will be the condensing oil boiler, BUT it is not available just yet!

Hi Joe@Buderus:

I called Buderus yesterday and didn't get very far. This is a good forum!

Is there a cost savings for buying the G125BE package verse purchasing similar components w/ a G115? Easier install? i.e. what's the purpose for creating a package?

How can homeowners find out if a contractor is certified?

The fact that certification is needed for installation seems to imply, to me, that the system is complicated. Will homeowners need certified service techs for yearly maintenance? Will yearly maintenance cost more?

Thanks

G125

The G125 boiler is sold as a kit due to the components are designed to operate together. The burner is wired for operation with the R2107 control only. The G125 boiler block has slight modifications and should only be operated with the Buderus burner. The burner is designed to operate with a tiger loop set up, so it was decided to include it. At this time, it is suggested to contact Buderus or the local distributor for a listing of certified contractors. Training has just started and is ongoing, so the list will continue to grow. Buderus is offering training to the technicians on the proper installation and operation of the equipment to help insure success. Testing equipment and tool kits are also offered to the trained contractors so servicing and parts should not be an issue.

Haven't put any of these in yet Matt, I went up to the training class a few weeks ago though, was VERY impressed!

89 v 87? What is the payback?

Cool technology yes but lets be realists here. What is the payback for a 2% increase in efficiency? LONG F'ING TIME. Lets wait, get up to 93% or better and THEN start the conversation on BlueFlame. Until then, I applaud Buderus for the "next" leap but it is not enough.

Robert O'Brien

The

primary benefit is low Nox not increased combustion efficiency.If the oil industry doesn't take the lead in reducing emissions it will eventually be legislated,thumbs up to Buderus for bringing this technology to the USA.If it weren't for the modulation most condensing boilers would have a very long payback as well in most retrofit applications.

Dont' forget the clean burn

This boiler will have very little (if any) of the build up of soot as a normal boiler. This will make cleaning much easier and more thorough. A normal oil boiler is never able to be cleaned 100% and degrades its efficiency after a season and that continues. The blue flame technology hopefully allows the boiler to maintain that high efficiency for a longer time and THAT is the payback,

I have to disagree with a "normal" boiler having soot buildup.Soot is not normal,any currently available oil boiler should not produce soot,period.If it does,the cause should be found and corrected. At $3+ a gallon any older burner that does should be replaced.
There will be some sulfur and scale that should be removed from the heat exchanger but soot should be unacceptable to everyone.I'm looking forward to getting up to Buderus and seeing for myself!

Outdoor reset control

Most of the savings is with the ODR control, not AFUE, right?

Darin Cook_5

Another question

If 167' is the design temperature limit in Germany, does that mean that even their standard oil boilers based upon a 20' or 30' delta T operate in a condensing mode most of the year? Is that the reason for the silicone injection process in the boiler castings? How low of a setback would still be permissable using a 2107 logamatic? Inquiring minds want to know!!

Sorry Robert

I certainly MENT Sulfur and Scale not Soot!!

Thanks for catching me, but do you agree that just about every oil boiler degrades with time as a "perfect" cleaning is virtually impossible and in real life conditions never achieved??

These conditions are what I was told would be possible with this burner/boiler combination. Certainly close.

Scott,Sorry

I'm touchy about soot,it drives me nuts when people accept soot as a normal condition. You're absolutely correct about pin type boilers,you really can't get them back to clean as new very easily and it degrades performance tremendously. A 3 pass such a Buderus is very easily cleaned 100%,no pins and full access. I'm just trying to free up some time to get up to NH before Spring!

G125BE

The G125BE is a low nox, not a condensing boiler. From my understanding, Europe uses 167 degrees as a design temp verses 180 degrees (not everyone does low temperature radiant heating). The G"B"125 is the oil condensing version.

PTN

BE

Well, there is really a saving of oil because of the higher AFUE. The size with the highest AFUE reached nearly 90%. That is a large advance when you compare that with the G 115 and Riello yellow flame burners. The riello can only burn with 13% of CO2. The BE is able to burn with 14%. The blue flame holds the combustion chamber clear. Because of that you hold your high efficiency over the whole year. A other argument for the BE is the very service friendly structure. It is a pleasure to make service with that burner. A other point is the very reliable combustion. I know that the Riello burners have problems to start on very cold winter days with sealed combustion. The BE has a special adjustment for an optimal CO2 on every temperature. A lot of adavantages you have with this burner!

Cheers

Oil condensing boiler SB 105

On the market in Germany since August this year. Very efficient (AFUE must be nearly 94%) direct condensing stainless steel boiler with a two stage blue flame burner.
Not sure if it will come to the US one time.

Thanks for the insight,nice to see that this is read worldwide.Talk them into getting those condensing oil boilers over here!

It is interesting for me to read about that product here because I'm the responsible Buderus lab engineer for the US versions of G125 BE and GB 125 BE. The GB 125 for the US is already running well in our lab and it looks good. The longtime testing needs time because we want bring you an absolutely reliable product like the others with the name Buderus.
