Overview of the Logamax Plus GB142
The Buderus Logamax Plus GB142 is an efficient wall-mounted gas condensing boiler. Capable of horizontal and vertical venting, with or without a chimney, it is produced in four models with inputs ranging from 84,000 to 214,800 BTU/H and outputs of 22,700 to 196,600 BTU/H. The modulating boiler carries a rating of 90 percent AFUE.
The manufacturer says that the GB142 is unique due to its pre-fabricated, low-loss manifold. The design is intended to achieve improved efficiency and enable the boiler to be installed in a variety of convenient places. The manifold ensures a correct flow rate, and its simple piping helps with quick installation. The boiler can be customized for various flue systems, and add-ons, such as a high-efficiency hot water heater, can be easily installed. With an aluminum heat exchanger, the Buderus GB142 is equipped with advanced technologies and sensors for troubleshooting and integration of add-ons.

We've had our Buderus boiler since 2007 and heat about 4200 sq. Ft. With it. It is in a separate building that is 16x 24 and this is part of the total sq. Footage that is heated. There are filters on the return line and it is running with about a 50% glycol mix with the city of Saskatoon water. I try to run it with a 7 ph level. On an annual basis, I dismantle the boiler and do a fairly thorough cleaning. I must say that other then a few glitches I've had no trouble with it. A Couple of former co-workers and myself installed the system ourselves, one being a plumber/ gas fitter and the other being in energy management. I myself being an electrician. By reading the reviews I see I'm in the minority as far as customer satisfaction is concerned.

"Waste of money"
Started having problems in the second heating season. Parts are double what you would pay for other brands. Sensors, fan, air relief at the top, all went by year three. By year four manifold was leaking at seals, oval ring in back vent disintegrated. Had to have the whole unit removed for that. By year five a hole developed in the back case. Not the exchanger. Leaked water and carbon monoxide into the house. Finally had it removed. In a lifetime I will never earn back money that would have been saved in efficiency. Cleaned twice a year by service. Besides the cost of the unit, I spent probably close to 5k keeping it running for 5 years. Buderus, now Bosch was zero help. They gave up on these years ago.

"HEED THE BAD REVIEWS--a real problem"
I thought we just had a lemon until I looked online. No one has anything good to say about the Buderus 142 series wall mounted boilers. A nightmare to disassemble and clean--which we need to do twice a season. Even then, you can't get it clean enough to be efficient. In less than seven years it has eroded the heat transfer fins almost completely away. Add me to the list of completely dissatisfied customers. Looking for a replacement that is better engineered for maintenance and longevity. Terrible product.

Installed 2009. Still under warranty, but Bosch will not honor it. Leaking. 3 people came to look at it -- all of them said this is not a good system. All of them said I should replace rather than fix.

"Great Boiler, 4 Years Old"
Recommended by installer, and have had no problems at all with unit. Very efficient, quiet, heats 3600 sf house & indirect hot water well. Annual maintenance (cleaning) is done by certified staff, and I've had no problems. There was a minor pressure adjustment that had to be made once, and the ignitor/ion rod will need to be replaced soon (apparently should be done every 2-4 years anyway) parts cost $150 & easy to do. I'll wait until next cleaning since having no problems. The parts are relatively expensive, and it is crucial to get a proper installation by someone who knows all the things you have to do to tune these things right. After that, no complaints at all. Looks like the aluminum heat exchanger is eroding & may need to be changed in a few years, but so far no big problems. Would have preferred a stainless steel exchanger instead of aluminum. They opt for aluminum in Europe due to higher fuel cost & better efficiency, but I think stainless steel is more durable for the USA.

"Exhaust manifold corroded"
Recently, as I was checking my mechanical room ceiling, I noticed a hole on the exhaust manifold of the Logamax Plus GB142 boiler. When we ordered the part, the Buderus person knew immediately what the issue was and for $109 they shipped us the new part. First of all, that should had been a recall because they are endangering the life of people by allowing CO to pump through the house. There should be a class action lawsuit against them. Second, they have one of the worst technical support and customer service in the market of any technological product that I have dealt with. Third, who in his right mind will design a replacement part that you need to take the boiler off the wall in order to install a foot long plastic drain pipe that their genius engineer wanted to go behind the burner? It is amazing that they are still in the market selling boilers. I have already one of my neighbors tell me that he had to throw his Buderus boilers to the garbage and move to a different company. Companies like Buderus should not be selling anything. They are horrible.

"Buderus GB 142"
I bought a Buderus Logamax Plus GB142 in 2010 and paid $8,000 for the product with installation. This heats my water and I have 5 zones for baseboard heat in my home. The first year I had it I was very pleased. It ran smooth, was very quiet and we always had hot water. The next year I had to put $700.00 in for “routine maintenance”. In 2012, the boiler started to leak and I had to pay another $800.00 for parts and labor. To top it off, the boiler relief valve failed last year and it flooded my basement and cost me over $25,000 in damages. Then this month the fan failed and the condensation pumped cracked and I spent $400.00 in parts to do it myself. The local service contractor wanted $1,200 to come to my home and fix it. Moving forward, I plan to maintain this myself and I have had a difficult time finding someone who knows this system and can maintain it. From the contractors I have spoken with and the reviews I have read online, I wish I went with another product from the beginning! These things should last 15 years before they start breaking!

"Do not buy"
Boiler is 6 years old and has failed three times already. Logic board failed. Safety sensor failed. Fan failed. Lost heat and hot water each time. Replaced all for over $600. Needs more parts, because it makes a horrible noise. Those parts and labor will be over $1000. Gas valve can't be adjusted properly. Need a new one, for another $300. Circulating pump that came from Buderus with the unit is failing. Add another $200 to replace that. So, $2100 in parts/labor on a 6-year-old boiler. I replaced some of the parts, or labor would have been a lot more. And everyone who knows the boiler says the heat exchanger will probably fail when the boiler is about 10-12 years old. That will be another $2000+.

I am a building contractor and I installed my unit myself with the help of my local dealer. My unit has been running for over eight years with no problems. It provides my radiant floor heat, and my domestic hot water using less then 700 gallons of propane a year. I only had to replace the ionization electrode and hot surface ignitor once; a simple fix. Other then that it has run trouble free. I would install it again.

"Logamax Plus GB142"
These boilers are sold in many parts of the world. A well engineered product. I installed the two running in my home for 10 years, zero issues and zero maintenance. They also heat domestic hot water. Now that's reliability. If you want to have this boiler installed you need to do your homework for who knows how to engineer a hot water system or convert an old system to this type of boiler. The product is amazing. The installation and service resources can be the biggest source of an unreliable boiler, not only Buderus but many other brands with poor ratings.

"Worst water heating system ever"
It seems to me the only people writing positive reviews are the installers. This is the worst system I have ever owned & with what I have spent in the last 3 years to keep it running, I could have installed a new one. It is now broken again & I am going to scrap it and start all over. I cannot handle another $5,000 bill to just have hot water. Please do not buy a Buderus hot water boiler.

"Disappointed and frustrated"
I am very disappointed with my Buderus GB142-60. I purchased and had it installed about 2.5 years ago. I had some minor issues but the efficiency was only 90% (<95% stated) at last year's cleaning & tuning. The fact that only the high end turn off temperature can only be set and not the low end turn on temperature is very limiting. Finding a heating contractor to install it was easy but finding a servicing contractor was very difficult. Most of my local heating contractors will not service this unit. After trying for over a year to find someone, I called Buderus and they finally recommended a local contractor. I signed up for an annual service contract with a recommended contractor. They cleaned and tuned the boiler last December. Two months later, the unit shut down with a 6a error code which could not be reset. My service contractor found a corroded connector and repaired it. In addition, there was a water leak and it was determined that seals and a threaded pipe (#73149) needed to be replaced. I believe these parts failed prematurely, which is unsatisfactory. The parts could not be obtained by any local suppliers; therefore, the parts had to be ordered and expedited overnight for an overall cost of $600, of which there was a $140 charge for shipping and a $105 pick up charge. These 2 parts could be ordered via the internet for $84 and shipped overnight for $25. I am very disappointed that there were no parts available locally and that companies take advantage of situations when customers have no heat or hot water for 4 days. As recommended qualified servicing contractors of Buderus, the product is only as good as the people providing the customer service required.

I have been trying to get my boiler to run properly for over 5 years. This boiler is ruining my life. I am off-grid, which means I cannot afford for it to run without firing. It constantly refuses to fire (yet uses 8+ amps on pumps that run for nothing) unless the floor gets colder than 62 degrees, due to its high limit shutoff. For my floor to get to 62 degrees my house has to be about 55, so I cannot get heat until my house is freezing cold. Yet, on a sunny day, it fires up and runs perfectly. I do not think it is possible to hate anything more. 5 years of hell and I have had it.

"GB142/30 - 5 years and still running. Two- zone heating only, with baseboard radiators"
Installed in 2009, a GB142/30. It's heating an 1800 square foot house. So far I've replaced a Grundfos circulation pump ($90) and a condensation trap ($50) which melted at point where it is touching the unit. It is very important to clean it once a year. Next time I will look for a less complicated boiler,but I hope this one can last a few more years. Everybody blames the installer, but I don't have those issues because I installed it myself and hired a good electrician to wire this baby. There are no issues with wrong codes, no ice on the exhaust when done to the factory specifications. It is running well and the gas bill is low. To install this baby, some of those wizards were asking me $5000-$6000.

Nov 2009 $9650 for the burner and Super Store Stainless water tank installed. Feb 2013 $809 for new return connection pipe and lower locking nut and gaskets replacement due to leaks. May 2013 $2086 (that's two thousand eighty six dollars) for faulty Buderus header manifold that leaked. Aug 2014 Catastrophic heat exchange failure resulting in required replacement of entire unit as well as electrical components that got ruined due to leaking water and corrosion. I've asked my contractor for a price to put a new heating system that is not Buderus. Do not buy these machines!! They are over priced, unreliable crap!!!!

We have had a Logamax Plus GB112 for seven years now and it hasn't worked properly for more than one month ever since we've had it. Worse - the kind of customer service we have experienced from Bosch Thermotechnology is absolutely appalling. Whether it came from Bosch, Buderus or an affiliated company mysteriously called "MyService". From blunt denial, to ignoring or calls and mails, to having our wall demolished because it "had a negative impact on the outlet pipe" (sic!), to coming over for a "free check" and then sending us an umpteenth invoice - we have really had it all. Of all this, simply ignoring our calls for help is the worst. If one thing Buderus has surely cost me a few years of my life.

"Very Poor Service from Buderus and Distributor"
This boiler is four years old and the heat exchanger failed (so much for your experience Mr. J. Johnson in ct). This unit is used for radiant heat and domestic hot water. I have now gone over two weeks without hot water and Buderus is indicating it will be at least another 4 days. Thank goodness this did not happen during the winter or I would more than likely have thousands of dollars in damage to my house from frozen radiant heat lines. Stay away from Buderus and R. E. Michel Company.

"Working great and still going x 4 years"
I am not a plumber but hired a plumber to plumb my gb 142 and Buderus 80 gallon indirect storage tank. This little powerhouse provides DHW for my potables, and kicks ass for my radiant hydronic floors x 3000 square feet. Only after 4 years am I having to replace the $38 plastic condensate trap. I have never had to service anything prior. Its extremely reliable and has been idiot proof for the newbie that I am. The manuals are well written, and after reading them, I directed the plumber on the plumbing aspects since radiant heating systems are uncommon in Texas. Fired it up first time and no problems. I love it! Its an all in one wall hung system tidy and quiet, and packs a mean punch at a low monthly gas bill compared to the A.O. Smith it replaced.

I had a GB142 installed 4 years ago ran good for two years than nothing but trouble I have spent thousands first with the installer than a high efficiency boiler expert, it still continues to fail and I can't get any help from buderus. I have recommended several of these units and for that I am sorry I wouldn't buy another buderus for anything.
Other Logamax Plus GB142 Reviews
Overall, many of the technicians writing on online discussion forums report few problems with Buderus boilers and recommend them as quality products. However, at least one professional contributor on www.hvac-talk.com offers caution for consumers considering purchasing the Buderus due to a reoccurrence of blockages and other problems in the unit’s aluminum heat exchanger. This poster recommends homeowners purchase products with stainless steel heat exchangers for long-term performance. In another case, a homeowner posting on www.justanswer.com complains of his boiler starting and then quickly turning off. This time the problem seems to be with a defective thermostat sensor.
Logamax Plus GB142 Warranty
The Buderus GB142 comes with a registration-dependent, 5-year parts and labor warranty for residential installations. The heat exchanger has a limited lifetime warranty.
