@ March 6, 2014 9:59 PM in Need Help - New Gas Boiler for Steam System ProblemsLooks like your sight glass and safeties are against a wall too. This creates the potential of out of sight , out of mind with devices that should be always on your mind. This may also. be a code violation.
When you take new photos stand way back so we can see the whole arrangement. Include one with the gas line too.
@ March 5, 2014 12:17 PM in question on dry returnsAnd sorry about the confusion in original post. This is not the first time I did this.
The dry returns are vented.
I meant to say the end of mains and, if successful, attached a sketch of what I have. One loop is approx 30% shorter than the other loop. Hence, the half of the house served by the longer loop takes longer to vent. What I was doing, after reading the many posts on venting, was timing how long it takes the steam to reach the end of mains without the vents installed.
Naturally, the short loop vented first so I replaced that vent. Then waited for the other loop, but what I saw happening was the steam crossed over to the other main because it is above the waterline. I reinstalled that vent and it too closed. So, that means air is trapped in the larger loop. So, I was seeking confirmation that the conection should be below the NWL before I repiped it.
@ March 4, 2014 10:05 PM in question on dry returnsSorry! it is a two pipe system. what I want to ask is, should the two end of mains join above or below the waterline?
What I am seeing is the short loop vents fast and closes its vent..
Then,because the two end of mains join above the water line, steam crosses over to the longer loop,heats that vent until it closes and air is trapped in the longer main.
I believe they should connect below the water line so they stay isolated. Am I right?
@ March 4, 2014 8:34 PM in question on dry returnsmy header splits into two loops along the outer perimeter of house, circle back to boiler and connect above the waterline, then drop below the waterline with a single pipe. their vents, vent until they get hot. The condensate has its own return. I think by connecting above the water line, the shorter loop vents first, then it's steam pushes into the other loops return. forcing that loops vent to close and trapping air between two heads of steam.
@ March 4, 2014 7:46 PM in question on dry returnsI have a two pipe system with two mains and two dry returns. My question is. the dry returns come together near the boiler, should they connect above the water line, or below?
@ February 25, 2014 8:44 AM in another case for pesonal protectionThis first one might fall under Gross Negligence by contractor who incorrectly converted a pool heater from Propane to natural gas:
This second link would fall under gross incompetence by inspectors who "performed CPR" on first couple but didn't suspect appliances in pool equipment room and the Medical Examiner who dragged his feet reporting cause of death of first couple to be CO poisoning which would have prevented the third death.
So, when I read the Rocky Mount incident above, I wasnt surprised. NC promotes itself as a "business friendly state".
@ February 24, 2014 11:01 AM in another case for pesonal protectionin the same motel room in Boone NC for anyone to investigate.
@ February 16, 2014 8:45 PM in Kickstart THIS!I dont know how I missed that thread.
@ February 15, 2014 8:12 PM in Kickstart THIS!Knowledge, of course! that's why we come here.
actually, I believe steam has plateued because the market is shrinking. A 90%+ efficient boiler maybe?
@ February 11, 2014 8:02 PM in Meet The CozyI think you are ready for your appearance on Shark Tank!
@ February 10, 2014 10:15 AM in Meet The CozyWhat kind of aesthetic changes are you going to make to make it appealing to the eye (sorry, I have a wife of 25 years and I know without asking what she would say-she would love to lower the temps in a couple rooms with oversized radiators but not at the expense of decor. Form over function, you know.)
And, what do you anticipate selling these for?
@ February 8, 2014 8:04 PM in run steam boiler from generatorif you dont want to be bothered with noise and filling the gas tank, consider a nateral gas generator. But then again, if it only happened once in 17 years, it may not be worth the expense.
@ January 30, 2014 6:27 PM in Battery back up for gas furnace?who woulda thought a Prius to be a survival tool?
I have a rule of thumb: The solution has to be agreeable with my credit card and insurance company. Unless my life is in danger.
my brother has a prius. i'll do the research for him. thanks!
@ January 29, 2014 6:51 PM in Battery back up for gas furnace?and I read these treads whenever they pop up hoping to learn of a convincing way to do this but there are always special cases and caveats. Enough to make me wait and keep reading. I wonder why industry hasnt responded with a solution? Seems like a way to make some money. I imagine everyone who has ever purchased a Gorton or Hoffman vent would probably buy a backup system. I guess no commercial solution, outside a generator, is what makes me leary.
@ January 29, 2014 9:43 AM in Replacement air for combustion?I believe it is one sq in per 1000 btu input with a minimum of 12 sq inches opening to outside
@ January 23, 2014 8:02 PM in cracked boiler due to pipe leakof the world you are located. one of the pros on this board may be close to you.
@ January 22, 2014 8:49 PM in Vapor stathttp://www.mcmaster.com/#atmospheric-pressure-gauges/=qd9rwa
click on low pressure gages. get one that is calibrated. my vstat had a 16oz/sq in range so I got a 0-15 oz/in and found my vStat was accurate. code says you need a zero to thirty psi gage but i'd rather have the correct pressure relief valve installed and a gage that tells me something.
@ January 18, 2014 8:33 PM in Nest Thermostata. it is too expensive
b. yeah, the google wifi thing annoys me. I believe Google IS the NSA.
but I digress. I do know one steam system that uses a nest. It works as perfectly well as my Honeywell. If you like technology, go for it. But if you want to save money there are other things you can do.
@ January 8, 2014 8:42 PM in Steam Pressure Short CycleAs I am finding out. With this cold snap, my boiler started short cycling while trying to satisfy tstat from a four degree setback. Also, two radiators suddenly feel merely warm unlike the rest of them, which are hot. Radiator steam traps flaking out ? likely. But with the two largest rads out, boiler becomes oversized.
@ January 6, 2014 6:33 PM in radiator enclosers/efficencya very informative site if you have time.
@ December 30, 2013 6:29 PM in Boiler seal leaking...And a third. 15 years on a boiler is not much time and in my experience, most seals and cracks can be repaired. However, labor to repair may make it un-economical to repair. It may be equal to or more than the cost of a new boiler. The thing is, if you replace one seal, you have to replace all of them and you are paying for an overhaul. This isnt a big deal, but what happens if the boiler leaks again from somewhere else this heating season? Are you going to expect the guy to repair that as well on his own dime? Would you be happy to pay for a second rebuild yourself?
It is unfortunate that you have to deal with this in the middle of winter, but if it is "slowish", you have nothing to lose by asking others for an estimate to repair and one to replace.
also, see if you can determine what caused the leak in the first place. Good luck!
@ December 20, 2013 9:41 AM in best location for 0 - 3 psi gaugedo a search on this board for "presuretrol" you will find photos of actual installations that will help you.
