@ December 1, 2013 11:16 PM in Apprenticeship ModelToo bad people are so afraid to make it happen on a lager scale. Fear of unions and an overall paralysis is preventing us from moving forward. I'd like to see more unity.
@ December 1, 2013 9:20 AM in need a little informationStart with heat loss calc's for the house. If it's anywhere between 80 and 120,000 BTU's, my choice would be a Prestige Excellence as long as they would be happy with 3.5 GPM of DHW. If they need more, use a Prestige Solo Trimax with whatever size indirect is suitable.

@ November 27, 2013 6:59 AM in Hydronic Heating in IndiaSo far I haven't found any, but people say it's in the newer office buildings and hotels. What I have seen here is a huge population ready to work and very industrious with an incredible history and beautiful artifacts. And some unusual plumbing.
@ November 25, 2013 11:41 PM in how to heat the boiler only when the thermostat calls for heatYour Hydrotherm boiler has a Honeywell H8148J 1009 (or a close relative) aquastat controller on the front of the boiler. If you remove the cover with the power off and tell us how it is wired, maybe we can help. If there are any peripheral controls, it could complicate things. The best bet is to hire a pro to figure it out.
@ November 18, 2013 9:48 PM in Spread some cheer... and news about your business!Putting your name and face out to your customers helps your business. We send out postcards around Sept. with a picture of me working on a boiler, reminding them to call me if they haven't seen me for awhile. I get excellent response from those cards and it reminds old customers that have forgotten me. It also connects you to the new homeowner if the house has been sold.
I can expect a boatload of service calls when I get home next year. Traveling in India at the moment.

@ November 11, 2013 10:25 AM in I lost a job to a company that did this:they got the job. Wrong is so much easier than right.
@ 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.
