the quietest boiler in the world

The Buderus S120 is a 32 gallon IDWH. It has 3/4" boiler tappings and 3/4" domestic tappings. A Grundfos 15-58 FC circ handles the flow requirements nicely. It is in my opinion an excellent tank for the money.

    Another GB142 install

    I just finished up this install. The home was entirely electric heat and electric hot water. The GB is running two zones of staple-up onix controlled by the RC10 indoor reset controller. The Buderus S-120 indirect water heater will blow the electric tank away in hot water production and energy efficiency. The staple-up on one side of the home presented a sharp challenge and time consuming process of dealing with the spikes and staples the flooring guys had used at some point. The tops of my knuckles have all the bloody pin pricks to prove it. The folks who own the home also had to wait a long time for the hot water to reach the tap, so I installed a Taco 006 bronze circ controlled by the GB 142. No more waiting. The owners are very happy.

    Nice job Darin. You've got lucky customers. They've got a sweet system. Is that a 30 gallon tank ? Is the coil 3/4" , we usualys go 1".

    Very neat and well layed out. I like the painted board.

    Hey won't the nails help with the heat transfer :)

    Did you include the bandaids in the quote or did you loss money on that part. :)

    Great job and by the way , it is Really Quite.

    Quiet boiler

    What a forest of nails you snuck through! just looking at the pic, my knuckles started bleeding. Last job we had like that, I mentioned to the HO that his sweat equity could be put to use with a grinder. We came back to do the install a week later and it was the best "clearcut" I had ever seen!

    Kudo's to you and your crew!

    Another quality job

    Comfortable Home Tech treats each install like a masterpiece. I am glad you guys post your work, I show these photos to the companies who ask about the GB142 and how to install it. Thanks for buying at N&S and doing it right!

    What were they thinking with all of those nails anyway?!

    Nice work Darin the board with the strut clamps is a nice touch, I'd like to start doing that on my installs, saves on cutting 500 peices of allthread. Couple of questions though, how come you don't put a condensate drip tee on the 3inch exhaust? and what is controlling your radiant staple up temps? just the RC 10?

    Great looking job. Nice layout.

    It does look like the condensate tee is missing. Is it hidden in the joist bay?

    I havent install the Buderus indirect S120. Is it like a Superstor?

    Nice Job Darin

    Nice install Darin. Where abouts is this house located. I used to room with a Darin Cook from Northern NY. You by chance would not be the same person would you.

    Per Steve Grady at Buderus, the condensate tee is not necessary if you are going up and out the sidewall and immediately terminating the vent. the staple-up temps are controlled by the temp dial on the boiler and the RC 10 indoor reset controller. Thank you for the questions.
