We have Heat!

New boiler install, thanks to Dave @The Steam Whisperer.  A Peerless TC-II with a modulating burner.  The next project is to remove the old insulation and put all new fiberglass main insulation.

Is that insulation very filthy aircell or is it fiberglass with the canvas missing or heavily stained or what?

Neild5

Filthy aircell that is scheduled for abatement.  Once it is gone then insulate everything with fiberglass.

Very good looking job, some serious work there.

Questions; what is connected to the left of the pressure control?
Pressure transducer maybe to modulate the burner?

Then there are 2 closed ball valves for the bypass on the water feeder line......I know there must be a reason.
Thank you

Yes, it is a pressure transducer that is connected to the burner brains to modulate it. It has 9 steps from 100% down to 20%.
The 2 closed valves are there to allow easier throttling to skim the boiler.

Excellent, do you know what pressure this will run at?
Is this gravity return?

The plan is .5 psi or less, the vaporstat was turned up to 1 psi while setting the burner program,  it will be at .6 psi once it has it's final tweak.

That thing is a big one! Looks beautiful

That’s a mighty fine looking installation. Hats off to Dave.

That's the work of my techs... I am rarely on the jobsite anymore, except for some special control set ups. Matt, Diego and Bud were the guys that put this altogether and did the start up. We have some new welders that are doing very nice work....This is the second big boiler they did some welding on this fall. They only did a couple welds on this one to tie the 5 inch steam main back down to the 5 inch header.

The IC burners are much quieter than the Power Flame and there is support for them locally. Modulation control is all digital so you just set 9 points up on the curve and it will modulate between them ( think there is like 99 positions on the control).

1 pipe steam, gravity return, about 1, 150,000 input. We usually don't do modulation on single zone 1 pipe steam systems because if the boiler is sized right, it almost never builds any pressure to cause the controls to modulate it down.... it's off on the thermostat before pressure can build. However, they may install TRV's on the radiators, so the modulation may come in handy then.

WE are wrapping up the other big one. Same model but 1,433,000 input with a dual riser drop header. Risers and offset piping is all threaded but, header is welded. WE thread everything below the header, so changing out rotted pipng on the return 20 years from now won't require a welder to come out. Most of our competitors weld everything right into the boiler, so the boilers don't hold up very well and it very expensive to fix leaking pipes on the return.

Beautiful install as always  from you and your guys Dave.
