@ 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,
@ November 22, 2009 7:28 PM in Customers Staring Over ShoulderI like the company, but if I don't like the person for some reason or if I need to concentrate, I tell the person (nicely) that I start making mistakes if I'm not alone.
I notice that it's usually my female customers that hang around. They seems more curious and less apt to be embarrassed about watching me. I try to engage them in conversation; people love talking about their kids, favorite restaurants, travel, favorite meals to prepare, etc.
@ November 20, 2009 12:09 PM in Wireless Thermostatsagain. I've searched the threads for info., but some of the model numbers have been discontinued.
receiver: RX-3 (3 zones)
Can someone please provide current model numbers and more important, include any feedback and experience you've had with these thermostats, good and bad. I have a customer with a single zone system who wants more control of his system. The return manifold is in the garage next to the boiler and all ½" loops are available for the installation of zone valves.
@ November 11, 2009 8:02 PM in Boiler electrical protectionto use one on a Viessmann Vitodens that was acting up about 3 years ago. Ended up buying a Panamax M4T-EX Power Conditioner and haven't heard a peep from the owner since.
@ November 6, 2009 2:15 PM in knocking radiatorDo you have steam heating or hot water heating?
@ November 6, 2009 11:06 AM in K L or Mwhat to use:
M - Most installers
L - Limited use
K - Knuckleheads or government work
@ November 4, 2009 11:49 AM in old cast iron boiler tempI presume you have cast iron radiators? That is a fairly large boiler; you must have a big house.
Your outdoor reset control should be able to monitor return water temperatures. Make sure it limits return water temperatures to above 130° to protect your boiler from condensing . And to answer your question, minimum supply temperature should be 150° or above.
@ November 2, 2009 12:12 AM in Cleaning a Corian White SinkMy countertops are Corian. I'm no clean freak so they oftten get stained, but wash off easily with a wet sponge.
What caused the stain?
@ October 27, 2009 7:50 PM in Triangle Tube Prestige Excellence BoilerThe Prestige (heating only) and Excellence (Heating and DHW) are both top shelf boilers; easy to install, simple programming and trouble free operation.
The only drawback to the Excellence is that it doesn't put out a lot of domestic hot water; only about 3.5 gallons per minute. That means you can use one fixture at a time; any more than that and the delivery temperature will drop.
