Buderus GB and G 125 boilers

Darin Cook_5

Yes, I have installed the G125's. I am piping #3 right now. They are great boilers. I LOVE the blue flame burner. The reason I have not posted is that I am too damn busy installing systems to post here. Customers have been very impressed so far. I will have some numbers in the spring to see the actual fuel reduction that customers have seen.

I have a G125 out there with a 2-panel solar domestic hot water pre-heater. I have a GB 142 going in now with a 3-panel solar domestic water pre-heater. These systems should squeeze the pennies out of the fuel.

Buderus G and GB 125 boilers

Was wondering how many of you have installed the new Buderus oil fired G125 (89%+) and GB125 (94%) boilers??
Am installing my first two G125's next week, and have plans to install a dual boiler GB125 system soon.
The burner on these things looks great. THe cleanest blue flame I've ever seen.
Also looking for feedback as to the piping of the GB dual system. Want to have the units condense as much as possible. THe usual P/S piping, lead/lag, tekmar controls, injection pump system, that we would normally do, may not work as well as sticking with Buderus more on this system.

System will be radiant floors, small snow melt, and dhw load. Plan on sticking with the 2107 controls and misc as much as possible but will do Tekmar on at least the S/M, since we want to fully automate this, and we are very used to Tekmar.
Any thoughts?

thanks,
Steve

thanks for the reply Darin

Hope to be firing our first G125 up in a week or so. Also have installed the GB142 in LP a number of times and agree its a great boiler.
Looking forward to the GB125 which is a month or so away from now.
Done a few solar panels w/ great dhw results, but really want to see what the big $$$$$ Buderus solar tank can do. Sounds like it is able to suck just that much more out of the panels. Love to see a decent amount of radiant floors heated off one of these things as well as dhw.

Love the boiler!

Thanks for the comments guys. Have installed 3 of the G125 boilers since I started this post. Have not had time to be on this site for a while, and was surprised to see it still here. One new construction site and two went in to replace old beat up, inefficent systems.
Just fired up a G142 today. Have installed a number of these and love it too. Even if we only have LP here. If any kind of head load the oil fired meets most our needs.
Still not sure exactly how I will pipe the dual GB125 boiler system. Still a month away or so.
