Description
Note: Product Title reflects this boiler's IBR Net Output Rating
The state-of-the-art design of the GB142, with integrated controls, is a rare combination of outstanding quality paired with exceptional value. Utilizing advanced condensing technology, the Buderus GB142 Wall-Mounted Boiler maximizes the heating value of every cubic foot of natural gas or liquid propane. All GB142 Boilers now come with the AM10 outdoor reset control and DHW sensor for control of an indirect DHW tank. The GB142 is approved for 3" solid core PVC horizontal and vertical venting.
The small size and minimal clearance requirements of the GB142 Boiler provide tremendous installation flexibility. Thanks to the prefabricated low-loss header, the GB142 Boiler has the fastest installation in the industry. Specially designed with an appropriately sized circulator, this manifold ensures proper flow-rate through the unit. This feature greatly extends the service life of the GB142. By simplifying the piping, the GB142 manifold allows for quicker, easier, and trouble-free installation.

Product Q&A
13 QuestionsQ: WILL IT WORK WITH CAST IRON RAD.
Asked by JOE 12 years ago
Add your answer
Verified Reply- SupplyHouse StaffIt will, but keep in mind that condensing boilers can only approach peak efficiency when return fluid temperatures are relatively low (usually 140°F or less). Cast iron radiators normally run at higher temperatures (180°F to 200°F), so they are not always the best choice with a high-efficiency boiler.
Absolutely. That's what we have. Sent from my iPhone
Q: I have a home in Sandgate VT, it is an old railway depot which was remodeled as a home and is well insulated. 2200 sq ft. With hydronic baseboard heating and an indirect hot water tank for domestic hot water. The current oil burner which just expired this past winter after 30 years of service is rated at 180,000 BTU - as noisy as the trains this depot used to service. A local Buderus certified HVAC contractor has spec"d this boiler which at 91,000 BTU's is just about half the load of previous boiler. The million dollar question, will this boiler be able to heat this house on those 20 below winter nights? And the other question, as this is a modulating boiler which will be used to heat domestic water during Summer, what is the efficiency of this unit during this period of time.
Asked by Romulus Rex 13 years ago

Verified Reply- PexSupply StaffWe would recommend that you have a heat-loss calculation performed on the building to get a definitive BTU requirement. 91,000 BTUs sounds reasonable for 2,200 feet of well-insulated space (and many installers had a tendency to oversize boilers in the past), but it is better to oversize than to undersize the boiler.
We use this boiler to replace a 200000 BTU Ruud boiler installed in 1954. The house is a 1932 masonry semi-detached, is not particularly well insulated and still has the original windows and cast iron radiators. The house is 3300 square feet on three levels plus a basement, in Washington DC. We have enough extra capacity that we are adding radiator heat to the basement. We do have the advantage of a common wall with the neighbors, but it is completely un insulated. If your contractor has calculated this out, he is probably correct. The efficiency of this boiler is easily around double that of your old one. If you are uncomfortable with this choice, then buy the next size up at about 105000 BTU. Sent from my iPhone

Q: Can't decide between Burnham Alpine, WM Ultra and Buderus Gb142. It is for a two story 2050 sq ft house in Nassau County. Is 83000 BTU enough? The buderus is about 75000 BtUs.
Asked by vin 14 years ago

Verified Reply- PexSupply StaffOn Long Island, 35 BTUs per square foot is usually a safe figure, but every house is different. You'd need to perform a heat loss calculation to get an exact figure, but you may also want to try our BTU Calculator: http://www.pexsupply.com/pex/control/BTUCalculator
Q: what is needed to run it on propane
Asked by 14 years ago

Verified Reply- PexSupply StaffThe LP orifice that is included with the boiler can be used to convert the unit to propane following the instructions outlined in the manual below. http://s3.pexsupply.com/manuals/1282584627079/37686_PROD_FILE.pdf
Q: It is for a new home in ND, with minimal heat loss.. Home will be around 3000 square feet.
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou would be looking at around 30 BTUs per square foot, which, for a brand new home with minimal heat loss, should be sufficient (even in North Dakota). The only way to be 100% sure of your BTU requirement, however, would be to perform a manual J/heat loss calculation.
I had this furnace installed in October 2010 in ND. It was a significant decrease in BTU output from original 1964 boiler (140k to 91.5k for 3200sq ft plus a heated double garage) but the installer assured me that it would be enough - and he was more than right. We've never had a cold day in the house since its installation and are really impressed with the furnaces' performance.
Q: How many Square feet of infloor will this size heat?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThat will be based on the heat loss of the space.
I had one installed in 2005. My house is one story & about 1500 sq ft. It is installed in a laundry/utility room in the middle of the house. it is very quiet! I can not even here it running standing outside the room. My boiler provides hot water, heat through a coil in the air handler, & radiant floor heat! I Love it! Very efficient!
Q: Is this boiler capable of operating 3 heating zones and an indirect water heater?

Verified Reply- PexSupply StaffYes, as long as the meets the total BTU requirement.

Q: Will this replace my hot water tank also? If so what is the low limit flow (GPM)? Are these limits adjustable?
Asked by Frustrated 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou would need to use an indirect water heater in order to get domestic hot water with this unit.
Q: We have a sensitivity to gas. Does this unit have a pilot or allow any gas to escape into the house?
Asked by 15 years ago

Verified Reply- PexSupply StaffThis is a direct vent unit with surface ignition. You should have no problems with it.
Q: Does this come with the low loss header manifold, or is that sold separately?
