@ December 18, 2009 12:31 AM in Old Cast Iron residential Boiler HelpHi JL:
The combstion analysis tells you a lot; it's like a smog test on your car. High carbon monoxide (CO) levels would indicate improper combustion, perhaps caused by a clogged heat exchanger that needs a good wire brushing between the sections.
Would you like to be the mechanic that tells his customer that he needs a new car when all it needs is a tune up?
Get a combustion analyzer and take a reading of the flue gases; then clean the sections and take another reading; odds are that the CO levels have come down.
I had a customer once that had a Hydrotherm steam boiler; his mechanic told him that his boiler was a sectional boiler, that it had no flue passages to clean. As you know, it's just like your Peerless boiler and it has sections that need to be cleaned.
All the best,
@ December 17, 2009 11:53 PM in Noisy one pipe steam system in PittsburghLike NBC said, I'd lower the pressure even more, like down to 1 or 1½ psi.
Other things to look at:
- Check to see for main vents, i.e. do you have them?
- Near-boiler piping, i.e. has it been piped correctly to allow for dry steam
This might be a job for......................a steam PRO. There must be plenty in Pittsburgh.
BTW, there is another forum called "Strictly Steam"; you might get additional responses there.
@ December 12, 2009 7:12 PM in European style panel radiators and cast iron on same zone?but you should cast around for other options. Sorry, I just don't like fan convectors, mostly because none of my customers who have them like them. I'd even consider installing a panel radiator on the ceiling; call it an art object.
@ December 12, 2009 12:49 PM in European style panel radiators and cast iron on same zone?Have you ever had a kickspace heater? Yes, sometimes it's the only option and then you've got to live with the noise and lack of (in my experience) adequate heat. If you have any wall space available or even the bare end of a cabinet, install a radiator or better yet, a towel warmer.
@ December 10, 2009 11:04 PM in Teledyne Laars jvt 125 noise problemI serviced a Lochinvar RBN09; looks, smells and feels just like a Laars Mini-Therm. The owners were complaining about harmonics and knocking. Luckily, the installer had piped a by-pass with a gate vale and when I started to open it, the sound went away. Too bad it's not a ball valve
My take is that these boilers with copper heat exchangers will tolerate low flow until they get older and then they start complaining. It's like the human body; when we're young, we can withstand all sorts of extreme conditions, but when we get older we start to complain. And we have by-pass options as well.
@ December 10, 2009 10:31 AM in wall hung non condensing boilersand maybe a vent. Yes, it's a pain in the butt and more often than not, the trap primer fails.
But installing a proper drain will free up your selection of boilers and you can choose a small mod-con with temperature responsive controls that will lower the customer's fuel bills and keep them cozy comfortable.
And I don't know of a small, wall-hung, non-condensing boiler that's reliable.
@ December 9, 2009 9:05 PM in Doesn't usually snow herein front of the bridge are San Quentin prison in Marin County, across the bridge from Richmond.
@ December 9, 2009 8:14 PM in trouble with taco thermatic bye passYes, I think I know what you mean. We installed a few Burnham wall-hung boilers when they first came out; perfectly sized for many of the small jobs we had. But that by-pass was a real troublemaker. We did something, but I don't remember if it was disabling the pump or removing the guts of the by-pass.
@ December 9, 2009 8:01 PM in Burnham: Flame Sensor problem or something else?ignition control module (ICM); the pilot will often rectify properly, but one of the relays in the ICM may not close the circuit to power open the burner. Usually a Honeywell S 8610U 1003 universal replacement; there are also others.

Is that Bill Clinton?
@ December 9, 2009 10:55 AM in Doesn't usually snow herethat it can always be worse.........or better for that matter.
Timco: I'm in Berkeley and I didn't know there were any Bay Area Wallies out there. Our temperatures are about 10° warmer than yours right now.
@ December 8, 2009 11:04 PM in Doesn't usually snow herebut the temperatures have been dipping into the 20's with some dustings in the hills.
Needles to say, I've been busy with "no heat" calls. It's good because the Summer was slow.
@ December 6, 2009 2:54 PM in Odd radiator pipes setupBefore you start cutting holes, I would check the pressure on your system. If I'm understanding your set-up correctly, your boiler is in the basement and the piping for the top floor radiators is in the ceiling of the upper floor. That means water has to be lifted about 30'. The water pressure gauge at your boiler should read at least 20 psi.
If your pressure is good, check for air bleeders on the roof or back in the boiler room. Many installers were very crafty and they would pipe a ¼" copper line from the highest point in the system back down to the boiler room and then put a valve on the end for easy purging.
@ December 6, 2009 10:27 AM in Water coming out of newly replaced ventand let us know the outcome. I'm mesmerized.
That radiator sounds permanently waterlogged (corroded and blocked air vent tapping?). Either that or there is a dip or corrosion in the piping near the radiator; accumulates water that gets carried into the radiator when steaming.
@ December 6, 2009 10:05 AM in Radiant questionthe same thing as a thermostat. I'd go with a thermostat since an 18-gauge thermostat wire is easier to install than a capillary tube.
@ December 4, 2009 11:34 AM in Glowcore parts??????I think many of us have serviced at least one Glowcore and have come to the realization that it's a lost cause. I'm surprised that you came along one that has lasted this long.
@ December 1, 2009 3:18 PM in Radiant questionwill the room with radiant heat warm at the same rate as the rooms with radiators. Like you said, the correct answer is to make it a separate zone.
@ December 1, 2009 9:57 AM in Radiant questionI would normally install plates as well, but since this is such a small area it will be a lot easier to run the tubing in the joist bays without plates at the same temperature as the radiators - around 180°; insulate under the tubing and leave an air space to allow for convection. You can tie it in to the existing living space zone if the other rooms have hardwood or make it a separate zone.
@ November 29, 2009 4:13 PM in Series 100 pump vibrating and noisyit should be said that the deterioration of motor mounts is primarily due to over-oiling.
@ November 25, 2009 1:08 PM in Teledyne Laars jvt 125 noise problemI've seen (heard) this a lot on Laars boilers. Like others have said, it might be some kind of deposit on the heat exchanger (HX). But I've always thought it was not enough water flowing through the boiler. The HX on the Laars is made out of copper and has excellent thermal conductivity...........when there is enough water flow to pick up all the heat. If only one or two small zones are calling for heat, the HX can't pass off the heat as quickly as it is picking it up from the hot gases and it starts to complain.............in this case, it sings.
My solution would be to repipe the near-boiler piping to primary-secondary. That way, the primary pump will satisfy the flow demand of the HX.
@ November 22, 2009 7:31 PM in Wireless ThermostatsThanks Scott, Dave and Glenn. I'll do some research on those products in the morning.
All the best,
