Buderus G124X Boiler Overview

The discontinued Buderus Logano G124X gas boiler has an AFUE rating up to 84.6 and ranges in its three available sizes from 74,000 to 132,500 BTU/H. The boiler may be installed in closets or on combustible floors. Venting can be directed out the chimney or a sidewall. According to the manufacturer, installation is made simple due to the unit’s adjustable rubber leveling feet.

The G124X is manufactured with a Buderus patented product: flexible cast iron injected with silicone. This material reportedly makes the unit resistant to corrosion and thermal shock during rapid temperature changes. The blue enameled, heavy-gauge steel jacket features 3 inches of insulation to prevent heat loss. This Buderus boiler has low emission, stainless steel premix burners and the flue ways are tightly sealed.

Additional options on the G124X available to homeowners include the choice of a standing pilot light or a more efficient intermittent ignition. It can be converted from natural gas to propane use and accessories are available such as Logamatic control, a vertical flue kit, circulator pumps and cleaning brushes.

"Overall I'm satisfied, though there are issues"

4.0 rating
Somewhat Satisfied

Have had a G124X for over 16 years. Overall I'm satisfied, though there have been bizarre issues over the years. For example, in the first 5 years I had to replace 4 thermocouples, until the Lilco service guy decided to put in a "husky" thermocouple; then I only had to replace it 2 more times in the past 11 years. I also have replaced the FK sensor 4 times over the years, and no one can give me a good reason why. I have been replacing them myself and now purchase two to always have a spare in hand. Also, it was first installed by a company here on Long Island who was terrible, though at the time the only Buderus supplier. No one else wanted to get involved, especially Lilco or Lipa or whoever it was back then. I had a switch also fail that I replaced myself. When it works, though, it is terrific.

"Poor product, worse service"

1.0 rating
Very Unsatisfied

I purchased a gas boiler with a logomatic r2107 controller in 2008. Had a very smart guy install it. The circuit board cracked on the furnace (2011), the installer came back and found the problem and soldered it. ( no big deal, it happens) That took three service calls to find. My real complaint is the logomatic controller. This thing does whatever it wants. The thermostat is set at 68 but the control sets the temperature wherever it wants. i.e. its -34 outside right now, the thermostat is set at 68F, the temperature in the house is 78F and the boiler is still running. ( I like the feature where I have to keep running down the basement to see what the temperature is) I shut the main power switch off and turn it back on to heat my house when it gets real cold like this, otherwise we roast. When it is around 32f (0C) the house is cold,can't maintain the 68F. Most nights we go to bed and can't fall asleep because we are roasting then wake up to a cold house'the opposite of what I would like. The service manual is poor and confusing and contacting Buderus service is a total waste of time. I can not believe any company can give such poor support without it being done on purpose. As soon as it warms up I will call my service guy and have him remove the logamatic R2107 and install a regular old fashion thermostat and temperature control where I just have to go down and turn up the boiler a bit when it gets real cold. I may not get my money back but I will enjoy smashing the piece of crap with a sledge hammer.

"Loudest boiler i have ever heard"

1.0 rating
Very Unsatisfied

I had a new Buderus boiler installed. at first it was a bit noisy…but tolerable. after 4 years ,this thing ((((shakes)))) my entire 2 story farm house. I have had the installers back numerous times about the "marching band" noises that come from this thing. as I sit here typing this review, I am waiting for the "expert" to show up and look at it for the 6th time.it sounds like someone banging on an empty 55 gallon drum with a rawhide mallet.it is so loud at times, I have to turn off the boiler and plug in an electric heater in my bedroom just so I can sleep through the night.watching tv is a near impossible task without maxing out the volume on the tv set….AND You can still hear it banging over top of the tv volume. dont buy one!

"GB 142 boiler high effeciency"

1.0 rating
Very Unsatisfied

Boiler fan assy had to be replaced last year for $800.00 then boiler started leaking, new gaskets replaced, then connection to boiler was defective and blew out. New part was not available from Buderus, and upon inspection, boiler unit female connection on boiler had only two usable threads in the boiler. I had difficulty getting parts. Service Experts had to get part from upstate New York. One year limited warranty on boiler quite different versus 20 year warranty on previous cast iron boilers.

Other G124X Reviews

Posters on various HVAC websites consider the Buderus G124X gas furnace to be highly reliable and efficient. However, a few homeowners on these sites claim their energy bills have increased since their G124X was installed. In cases such as this, professionals emphasize a heat loss calculation must be done by the technician to ensure an appropriately sized boiler is installed. It is suggested by these pros that when energy costs rise following installation of a new HVAC product, the cause is due to errors made in the installation process and not the home’s new equipment.
