Best Boiler on the Market
By Chris Johansen
from Fairbanks, Alaska
Comments about 74,000 BTU Output Cast Iron Oil Boiler - Chimney Vent:
I installed a Buderus G115 with a Riello 40-F3 in my 5000 sf house 17 years ago. I live in Alaska and my boiler has over 31,000 hours on it. I clean the boiler and replace the nozzle once a year. I have never even had a boiler technician look at it. Absolutely runs like a champ with minimal maintenance. Would not consider another brand.
Bottom Line Yes, I would recommend this to a friend

The Cadillac of boilers!
By Cozy in Vermont
In October 2009 I installed the Buderous G115-3 74,000 BTU boiler on top of a Buderus L160 indirect fired domestic hot water heater. I also purchased the Logamatic 2107 controller with outdoor temp sensor. This setup replaced an old 136,000 BTU Atlas boiler with internal DHW coil. So more than 2 years later all I can say is that this is a fantastic combo that is very efficient and provides lots of hot water too. The Logamatic controller took awhile to tweak (with helpful telephone instructions from Buderous customer service) and now provides perfect setback based on our lifestyle and outdoor temperature. I have averaged better than 20% fuel savings over the last 2 years and we never run out of hot water like the old system. I can clean the hemispherical combustion chamber myself (It still isn't sooty after 2 heating seasons!) and it will never need a liner or target replacement like other boilers. This thing burns CLEAN. The only down side is the chosen AFG burner is a lot noisier than the old AF burner we had before. The German Buderus products are so well made I do not understand why anyone would want a Weil McLain or similar when you can have a MUCH higher quality Buderus for virtually the same price. If you appreciate great engineering and use of latest marerials and technology, you will really like the Buderous stuff.

Great boiler but beware it does not heat your hot water, only the heating system.
Very nice boiler

What's to say... Its small and quiet. After a few seasons of heating I might have a more complete opinion...
