Uneven Heating & General 20's Trane Advice
ChicagoCooperator
Member Posts: 363
<span>Hi, this is my first
post here. I'm the board president of an </span><span>8-story building built in 1927. I need to
gain some knowledge about our heating system so I can lay down the law with my
neighbors about maintaining our system and modifying it. </span>
<span>There are two units
on each floor, one has a predominantly north exposure, the other south. The
building was originally built with Trane convectors recessed in the walls behind
a wooden cover with a metal chase and register and damper about 18" from the
ceiling. The bathrooms and kitchens just had, as far as I can tell, simply a
metal box in the wall creating a chase for convection with steam pipes inside
them. One bathroom on each side of the building is at an outside corner and the
convective heating proved inadequate and most have been supplemented or replaced
with radiators or cast iron baseboard (though some people with new windows
report they can turn off the radiator). Except on the eighth floor, which has
smaller units with different layouts, all the convectors are on inside walls.
There was also no individual control of the convectors beyond the dampers, which
I assume was intentional. </span>
<span>Many of the
convectors have been replaced with radiators because the unit owners "felt cold"
- the building has always been owner-occupied and there was lax enforcement of
proper practices for modifications to the heating system. Currently, some people
are cold while others are boiling hot and it seems that the output from some
convectors is minimal and possibly even from a few selected risers as well.
</span>
<span>We've been told that
the boiler needs replacement, it's the original boiler, I can't remember off
hand the manufacturer. It's on a Heat-Timer EPU controller, which seems to
"stick" when we have changes in temperature, as is common in Chicago. I also
suspect it isn't set correctly and may not be the correct unit/module for
convectors. </span>
<span>Obviously there will
be some difference between north and south sides of the building on sunny days
or really windy days. </span>
<span>Here's my basic
questions;</span>
<span>1. How are the
convectors vented, I've seen mention here that the Trane system was unique.
Could this be responsible for the underheating problems?</span>
<span>2. Mixing of
radiators and convectors - bad, right? </span>
<span>3. When, and if, we
replace the boiler, can the building be "zoned" based more on interior
temperature rather than our current system or is there a better way to do it?
</span>
<span>4. What's a good
source of information for me to bone up on our system? </span>
<span>5. What else should
I know? </span>
<span>Sorry for being
long-winded in a first post. </span>

can't stop a trane...
but you can speed it up.
you are so lucky to be in Chicago, where one of the most expert pros here is located:

read a few of his posts, and see if you like his communication slills, and then give him a call.--nbc0 -
Thanks
Thanks, I noticed that.
I should also have mentioned the photos in the first post are of one of my convectors and the radiator in one of my bathrooms (pre-painting the room) which shows the original lower register for the convection heating in the bathroom. The upper register was removed at some point and plastered over.0 -
Chicago Steam Pro
I'll second NBC's recommendation. Dave Bunnell is one of the top steam heating pros in the country. His phone is: 1-877-567-7070 He's very innovative and can get the maximum from a system in both comfort and efficiency.

And I'll pile on...
with the recommendations for Dave. And I will add that in a somewhat complex system such as yours, comments we all might make over the 'net would be mostly whistling in the dark.
Do get hold of Dave and get him to come over. Your situation is not impossible in the least, and I would imagine that he can greatly increase your comfort and lower your heating bills at the same time!Br. Jamie, osb

Keep us in the loop
We love to hear how these restoration projects turn out, so please keep us in the loop with things as they develop!
One thing to remember is that when you have repaired all the deferred maintenance, the fuel use will be less, even though the comfort level has improved for everyone. Don't let anyone be afraid that the improvements you are about to make will cause an increase in fuel cost, quite the contrary!!--NBC0 -
Hope I didn't jinx myself...
I hope I didn't jinx myself by posting yesterday - the burner had to be reset twice last night... I had to learn to do it (easy) and our janitor thinks he has solved the immediate problem.
I meant to get some photos. Our boiler room needs some tidying up. It's a Heggie & Woodruff if I remember correctly and originally also provided domestic hot water.0 -
night time reset
why does the boiler need resetting?
why should it be replaced?
what is the janitor's fix?--nbc0 -

Reset
I think he said the calibration port was dirty, but I was too tired at 6:30. I went down to see what he was doing. It was a purple rod to the side of the burner, but part of the assembly which entered at an angle.
The red warning light which said "FGS or FSG Alert" was on and he had me open the panel and press the reset.
I haven't heard if this has worked yet.
We were told this by a "boiler guy" - the reasoning seemed sketchy to me. The correspondence was via our building manager and was really only a proposal/bid rather than a why. We had a crack in the boiler repaired this summer and the boiler itself has seemed to work fine until now. There is some rust at the base of the boiler but I think this is in the supporting base rather than in the boiler proper.0 -
Dave is the Best around!
Call Dave Bunnell. He can assess the system and its problems and will give you the best advice for repairs and changes necessary to get this system back into shape so that it can last another 80 years.Dave in Quad Cities, America

Thanks Again
Thanks for the advice. So far everything seems to be running smoothly but we'll see after our coming cold snap.0
