EDR. Unless they are thinking about putting the rads back in the bathrooms, why do anymore than the total EDR+ piping pickup. Matching the radiation was the right pick. The envelope would not make too much sense on a replacement for the boiler unless you were adding more radiation. Chris

Deep in the Blueblood section....

of Boston I'm quoting on a steam boiler. Triple decker, brick exterior, quite old. The existing boiler (g/f) has an input of 399,000 btu/hr, oh, it's a steamer w' 2" header, equalizer, w' a 4" takeoff.to all 2" risers. I counted up all the rad tubes, columns and sections. 18 rads total for all 3 appts. The EDR comes out to 120,000!?
I know he's removed 3 or 4 rads (bathrooms went to electric). Says every winter he goes by and tenants have the windows open. I did not do a heat loss on the bldg, as I figured if the tenants are roasting to the point of opening the windows, the connected rads are more than ample. I'm leery of my #'s on the EDR which came out so low. Any thoughts?

Dan's Missing rads

I think I remember Dan writing that you need to add the missing rads into the edr. I think he said "count the ones piled in the garage". I believe the reason for this was the piping was still there and would condense steam. Bath rads couldn't have been too big so I would guess an edr on them and add them to figure my 1.33 multiplier.

I wouldn't do it

without the mssing info, I agree with Dale (and Dan?). I had one that almost bit off on of my sales guys years ago in Cambridge.

Are you the Ernie J. from Natick originally from Arlington???

A couple of questions befeore I "respectfully disagree" with my compares....Are the staeam pipes STILL insulated?If not, will they be? Makes a big difference in the big picture.(Been there, done that, got the T-shirt from the "abatement company")
Have the "normal",re:new windows/doors and insulation upgrades been done? If so, I think I MIGHT add a bit to the pickup factor, but.... Where are the takeoffs capped? At the main, I wouldn't worry about. At the old terminals, would add a bit, but a properly capped pipe won't let steam in, if air can't get out. Really great main venting will help quite a bit too. Just a couple thoughts. Chris

Ernie........

I work in Boston every day and want to offer a small bit of advice. Find out what is controlling the boiler. For example, if there is only one thermostat in the building and that is located in a room with the radiator valve shut off, then the rest of the building will overheat. By careful that you don't offer a solution to a problem that can only be overcome by informed tenants.

From a Steam Idiot

If the rads aren't installed how can you possibly include their ability to condense steam?

If their piping is still there and capped off how can you possibily even include the full ability of the piping to condense steam when the piping is unable to vent air?

The connections to the capped off risers/branches aren't "the point of no pressure change" but without an air vent at the other end how can they possibly transfer steam in the volume for which they were designed?

Hi George

I do live in Arl. Am not from Natick though. Born and raised in Arl., Ma. I remember you from Hazelton Supply. You helped me out once on a steamer in Watertown. Also I attended on of your classes @ NEFI. 'Old Timers Update' and took umbrage @ the name of the class
Thanks for all the responses. Yes one thermostat in Bldg.
Was looking into the Tekmar 269 for steam to ease the load during the 'shoulder' seasons. Any thoughts on that?

Aha, now I know who you are, hi!
