GB 142/30 pics

Ray Landry

Here's a few shots of a Buderus GB 142 boiler we installed today. This is definetly a boiler with alot of nice features. I really liked the RC 10 room sensor control, unlike the standard room sensors, this one is didgital and mesures in fifth degree incraments! Everything about the boiler is first class and very user friendly. I liked the inspection port on the pvc exhaust to check co on startup, ease of acsess into the bc 10 control for setting up dhw temps, ect. Also the 100 foot venting allowance is sweet! Piping and wiring where really simplified with the use of the pumping station and the pro press fittings.

duh forgot to add the pics

I can't see your pictures!!! How much more are the Buderus compared to the Munchkin. They sound like a nice setup.

Ray so what type of system the GB142 is connected to? Radiators, Baseboard, Floor Heat?

2 zone baseboard loops

Thanks for posting the pictures. We have hear many positive comment about the GB142. This unit has been used in Europe for the last 20 years. Thanks

cost of the boiler?

A variable based on reliability, labor and equipment costs.

Hey Joe are there any heating curve charts out that show the how the boiler temp modulates with the room temperature changes? IE: rc10 control is set to 'A' degrees, and room temperature is 'B' degrees, than the boiler will ramp up 'C' degrees?

dconnors

no charts,sorry

Boiler looks at set temp as compared to actual temp and the logic will determine where the boiler needs to be as far as modulation. If the temperature should overshoot the setpoint the circulator will post purge until the setpoint is achieved.

Thanks for the reply dconners, I'm still a bit confused when it comes to the RC 10 control though... I talked to kevin @ tech support today and he said that the bc 10 modulates according to the delta t of the supply and return piping and is not influenced by the RC 10 control... IE: if it's 60 in the space and you set the rc10 to 90 the boiler will not ramp up the heating curve until the delta t has dropped? He said that the rc 10 IS NOT an indoor reset control more like a device just call on the dry set of contacts to call on the burner... According to him in a few months there will be an RC 20 control to take care of modulation.... please enlighten me someone as to what the rc 10 actually does! Thanks.

Interesting...

Interesting mix of copper, bronze, and iron/steel.

I assume that the big blue block is something like the RMB series from Taco, i.e. a mixing block for low-temp heat emitters?

Looks like the primary loop got in the way of the water heater loop and vice versa. Piping it all might have been easier if the mixing block and the water heater were on opposite sides of the GB142. That way, the pipes of the two wouldn't intersect as much.

Also, is it OK with Dan to use the Wall servers to host pictures for sites other than the Wall? In particular, I am referring to your attempt to host pictures you posted here earlier at HVAC-Talk.

Lastly, try Irfanview as a free utility to rotate, crop, and resize images. Images that are smaller than 600 pixels show up best in these forums.

Even if The inderect was on the opposite side, the piping would not have been 'easier'. That primary loop comes pre piped that way w/ the GB boiler. Supply and returns for the secondary loop and inderect come out on opposite sides of eachother. The 'blue box' is just a buderus pumping station (consists of a grundfoss super brute, built in pressure bypass, and combonation isolation/temp guages. They also offer a 'mix station' which has a electronic three way valve. Thanks for the link for the photo editor, I hope I didn't offend Dan by using his site as a 'host'
