@ November 8, 2013 11:28 AM in Runtal baseboardsBaseboard (BB) has a built-in spacer that allows the heating element to be a couple of inches off the floor. It's part of the sheet metal enclosure and extends below the fins. Runtal radiators do not have that spacer.
@ November 7, 2013 10:12 AM in Baseboards not getting hotA few questions:
- Do you have a gauge at the boiler that reads pressure? If so, what is the pressure?
- What kind of pump do you have? Can you tell if it's working or not?
@ November 6, 2013 11:19 AM in Outdoor Sensorstraightforward is it? Especially with electronics. I guess it is what makes our job interesting, although it would be nice to have a "fits-all" sensor.
Thanks for your help, guys.
@ November 4, 2013 6:25 PM in Outdoor SensorCan I use a Munchkin outdoor sensor to replace a Viessmann outdoor sensor? Are they both 10K?
@ October 30, 2013 8:07 PM in Mono flow kicking my butt....install a ball valve between the two venturi tees. Use it once to purge the air out and then leave it open for operation.
Twenty inches is too close; they should be 10 feet apart, otherwise the flow of water will not want to go through the branch.
@ October 27, 2013 8:19 PM in Steam? Hot Water? Force Hot Air?Converting to hot water has many problems:
1) Leaking radiators and fittings because hot water runs at a higher pressure,
2) If you have a 1-pipe steam system, you have to install a return to the boiler from each radiator.
3) Radiators for steam are often undersized for hot water.
Converting to forced air? Yuk! Do you really want the noise and the discomfort of blowing hot air throughout your house?
Stay with steam. Click on "Find A Contractor" above to locate someone. If there's no one in your area, tell us where you are and we'll see if we can find one for you. The most important thing is to size the boiler properly and finding the right person to do the job. We can help you with that.
@ October 26, 2013 10:16 PM in Caleffi Troubleshootingall the Caleffi Z-One zone valve coils gave a reading of 22-23 ohms, so they were all good.
I found the short when I disconnected a neutral wire from the transformer to the "C" terminal on the 4 thermostats. This additional wire (other than wires to RH and W) provides power to the thermostat so you don't need batteries. I did a continuity test between C and RH to see if the short was in the thermostats, but they all checked out OK. I surmised that the short was somewhere in the wiring to one of the thermostats.
Thanks for all your help.
@ October 26, 2013 3:23 PM in Triangle Tube Prestige 110 will not startThe boiler won't fire if it's warmer than 68F outside (Warm Weather Shutdown). It could also be bad wire from the t-stat to the boiler.
@ October 26, 2013 3:19 PM in Caleffi TroubleshootingThanks, Hot Rod. I believe they are the Z-Ones, but what I need is a rating of the coil resistance. When I test a water solenoid valve on a shower steam generator, a reading of 560 ohms tells me it's a good valve. If it's a lot lower than that, it's a short. I just want to know that resistance figure for a good Caleffi valve coil.
I'm just leaving for the job now; more when I return.
@ October 26, 2013 2:01 PM in Thermostat WiringFor heating, we always connect wires to RH and W to call for heat. Until now, I never realized that if you connect a neutral wire from the transformer to terminal C on the thermostat, it will power the thermostat and you don't need to change the batteries.
Most of you will say "Duh", but I just never knew that.
@ October 26, 2013 1:45 PM in Caleffi TroubleshootingI'm going over there this morning and I'll ohm out all the coils. They should all be close except the one that's shorted.
Thanks for the tips.
@ October 26, 2013 1:07 PM in a question on EDRWow! That's a good question and I don't have an answer.
Theoretically, the radiator filled with steam at 215F will put out more heat than a radiator filled with 215F water, What is the difference in BTU's?
And if you look at the EDR table, the output is linear; there is no big jump at 215F where steam gives up it's latent heat.
@ October 26, 2013 12:28 AM in Caleffi Troubleshootingis a transformer with a circuit breaker...................at least for testing purposes.
@ October 25, 2013 7:11 PM in Caleffi TroubleshootingI've got a short in a 4-zone system; keeps burning out the transformer. I don't know if it's in the thermostats or the Caleffi zone valves (not telestats). Does anyone know the resistance reading on a good Caleffi motor?
@ October 24, 2013 3:27 PM in Sheetrock wall now or wait for new install................or at least, that's the way we do it.
But you might want to wait until you have an installer come in and look at it before you sheetrock. They might see it differently.
@ October 17, 2013 5:33 PM in I'm finishing up the seminar part of our business.with Ron to say that your knowledge lit a fire in me and it's still burning.
And along with Larry that we'd like to see you out West, business or pleasure.
@ October 16, 2013 12:00 AM in Webster Sylphon steam trapbut at this point, I don't want to upset the balance, if any. Most of the radiators heat properly and I'm afraid that if I start messing with the traps it will cause more problems.
All of the radiators are behind custom, non-removable enclosures with custom molding. If I want to get in there with my tools to work on the traps, the general contractor will have to tent around each radiator, remove the custom enclosure and then replace it. Obviously, the original builder thought that these traps and radiators would last forever.
The replacement elements require that the seats be removed and I don't know what it's like to remove a steam seat that's been there for 80 years.
@ October 14, 2013 11:41 PM in Webster Sylphon steam trapsupposed to look like? (Gordo, Steamhead)
Can someone post an infrared image of what a steam trap is supposed to look like?
@ October 14, 2013 11:17 AM in New setup mockup1) install a bypass around your fill valve for power purging.
2) I see that you want to install purge valves at the end of your returns. An easier way is to install a purge assembly. The piping is: boiler-hose bibb-ball valve-air eliminator with fill valve assembly-pump. You connect a hose to the hose bibb, close the ball valve, open the bypass around your fill valve and open one zone at a time. It purges everything; pumps, radiators, indirect, boiler........
@ October 13, 2013 1:39 PM in Munchkin HX leak---what are my options?epoxy to fix the leak until you come up with a solution. I see for sale in hardware stores specifically for fixing water leaks and from what I've seen from weekend warriors (homeowners), it works.
@ October 9, 2013 8:04 PM in Thermostat Questionof these instructions:
I believe that you want to connect your two wires to "R" and "W/Aux".
