@ March 28, 2014 1:27 PM in Vents spraying waterCan you post a sketch of how it was and how you changed it? That will help us help you.

@ March 21, 2014 8:09 PM in Pump with integral air ventB&G had what they called their Air Control Booster Package when I was starting out. The impeller spun the air to the putter edge of the volute and a volute-mounted vent spit it out. The price was too high and they discontinued it. Neat idea., though.
Everything old is new again.
@ March 18, 2014 3:54 PM in steam gorton valveThat's the air going back into the system. Steam systems breathe, just like us. When steam forms, it expands 1,700 times, pushing the air out of the vents. Then the steam condenses and shrinks, and the air comes back in. Happens on every cycle.

@ March 14, 2014 5:34 AM in Steam boiler questionsIt's a high-pressure boiler, used to make heat, to iron clothes in this case. You can't use it on a heating system for a building because its steam nozzle is too small for low-pressure steam. It's a used boiler and worth whatever someone is willing to offer you. It would help if you posted the location of the boiler. Thanks.

I think this may be domestic hot water.

@ March 6, 2014 7:38 AM in HELP with new steam boilerand that includes the pipes between the boiler and the radiators, has to be brought from ambient temperature to 215 degrees. That's a function of specific heat. It takes so many Btu to raise a pound of iron or steel one degree Fahrenheit. Since the 1950s, manufacturers have suggested using a pick-up factor of 1.33 for the piping, and that assumes the steam piping is insulated with 1" of insulation. I'd use that factor.
As for the risers being used as radiators, here's the EDR:
1-1/4" = .63 EDR per linear foot
1-1/2" = .73 EDR per linear foot
2" = .88 EDR per linear foot
@ March 5, 2014 2:02 PM in HELP with new steam boilerAre all your steam pipes insulated?
When you say "generous" what does that mean? How much have you already added to what's actually in the house?
A Btu is a Btu, whether it comes from burning oil or gas, so we look at the rating on the boiler.
The boiler's ability to produce steam has to match the system's ability to condense steam, which is why the measuring of the radiation is so important. If you're not certain, it would be good to get a steam-savvy pro in to do that for you.
Another issue is the piping of the new boiler. That has to be just right if you're going to be happy afterward.
I would also want to know why the Crown lasted only six years.

@ March 4, 2014 6:31 PM in Opportunity KnocksYou're very talented. I really enjoyed your stories. Thanks!

@ March 4, 2014 4:57 PM in Opportunity KnocksBut thanks! She really has an amazing way with words. She blogs about getting kids to love reading and writing. You can read some of her stuff here: http://www.kellyhochbein.com/
Crazy about her. Three more smart people are going to be feeling the same soon.
@ March 4, 2014 4:18 PM in Opportunity KnocksThis really is a great opportunity. She makes money for people. If I were you, I'd want to be one of those three.
