dropheader vs non

Does anyone know what the breakeven point is for a dropheader vs non. I know there are alot of variables, just trying to figure out if the expense is justified.



Dropheader piping and fittings so far add up to $800.

"Standard" Header vs Dropheader

Hi- In comparing a properly sized “standard” header to a drop header you first must consider that the piping sizes used should be the same as those used on a dropheader so therefore the costs will be pretty much the same on these items. The differences are:

On the installation:

The material side - it is the added cost of just a couple of extra elbows and pipe nipples.

The labor side- it saves time as the risers are much easier and forgiving to attach to the header pipe using a dropheader configuration. Depending on the difficulty of the individual job, I tend to think that the extra material cost comes pretty close to being balanced out by the labor savings from the ease of installation.  (There can also be a saving from not having to repair the hole in the basement drywall where your wrench impacted after being thrown by you when you got frustrated trying to get a “standard” header's fittings joined together  

             

Long range benefits of a dropheader over a "standard" header-

- drier steam means better efficiency

- less thermal expansion stress on the boiler sections

- easier to adapt to a new boiler if one is likely needed in the near future



Your piping looks pretty good and should be more efficient than what you previously had.

Thank you Rod.



Some of the main concerns were addressed:

- eliminating bull tee

- fixing the slope to the two mains at the bull tee

- removing the 2" pipe from old header

- raising the risers

- utilizing both boiler tappings

Drop header installation

If you could increase the header size by 1 size, you would slow down the steam even more. As shown, the 2 boiler risers appear to feed a header of the same size, so the steam would speed up a bit in the header. As seen, it will still be an improvement over one boiler riser, and no drop header!--NBC
