Buderus Logamax Plus GB142 Boiler Overview

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 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.

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.
