Snug it up,

@ December 21, 2013 3:24 PM in Connecting circulators - flanges

but don't wail on it.  Turn on the water and if it leaks, snug it up some more.

Low Down

@ December 21, 2013 3:19 PM in My opinion of NEST on steam

Thanks for giving us the low down on the Nest thermostats.  I was considering purchasing two of them for my radiant system, but I don't want one that will lock up on me or only respond when I wave my hand in front of it.

Also, displaying the setpoint vs. the actual room temperature is a drag.  No way to change that in "settings"?

Synopsis

@ December 21, 2013 3:15 PM in Hot water baseboard heating

Would it be possible to start a new thread offering a brief synopsis of the problems with this newly installed system?   I find it hard to read through so many posts to get to the true meat of BBHH's problems.

The main thing I picked up was that the pump for the indirect was piped wrong. I am also blown away by the installer's attitude and that he won't come back to fix things that BBHH is finding troublesome.  Has the installer made an appearance here on The Wall?

It will work if you have less than twenty-five feet of BB in the second bedroom.

As with Steamhead and Gordo, Ron is a superstar in my book.  They are all charter members of Heating Help and have always been ready and willing to help others in need, be they homeowners or contractors.  There is a special place in heaven for these men.

Too 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 information

Start 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.

I'm optimistic

Hydronic Heating in India

@ November 27, 2013 6:59 AM in Hydronic Heating in India

So 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.

Hydrotherm

@ November 25, 2013 11:41 PM in how to heat the boiler only when the thermostat calls for heat

Your 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.

That's a great idea, Kelly!

@ 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.

BB vs. Runtal mounting

@ November 8, 2013 11:28 AM in Runtal baseboards

Baseboard (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.

BB heat

@ November 7, 2013 10:12 AM in Baseboards not getting hot

A 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 Sensor

straightforward 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.

Outdoor Sensor

@ November 4, 2013 6:25 PM in Outdoor Sensor

Can I use a Munchkin outdoor sensor to replace a Viessmann outdoor sensor?  Are they both 10K?

Yes,

@ November 3, 2013 6:10 PM in Boiler header

you can.

You may have to

@ 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.

Stay with Steam.

@ 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.

On the job,

@ October 26, 2013 10:16 PM in Caleffi Troubleshooting

all 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.

Boiler start

@ October 26, 2013 3:23 PM in Triangle Tube Prestige 110 will not start

The 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.
