@ December 5, 2013 11:05 AM in Rotation IndicatorsI was thinking the same thing. Then it dawned on me......To verify operation....especially in a noisy mechanical room.
@ December 5, 2013 10:21 AM in Taco Bumblebee CirculatorAs Carl said, is there an underlying issue, that is making you look to the circ.? Uneven heating? A 20 degree DT in a baseboard series loop can give you that. The circ may be running at its minimum, and most of the heat given off at the start of the loop.
@ December 4, 2013 3:24 PM in BTU MeterFor every measure to make it fair, there are counter points. Can you charge more in an apartment, because you don't have enough radiation for the heat loss? I don't know the answer, but the question is, headache producing. Do the folks on the north side of the building have to pay more? Try and convince a person that it was fair for them to pay more for their unit, even though its the same size as another unit.
@ December 4, 2013 11:13 AM in Got an estimateThe best inspection can't predict when the boiler will fail. At 30 years, I would consider that boiler done. Since the near-boiler piping is boiler specific, if it fails in 6 months, the piping would have to be re-configured to the new boiler.
That's just a homeowner/ machinists perspective, and the pros may say I am "all wet".
@ December 2, 2013 8:48 PM in Thoughts on dense packing plaster walls?I believe open-cell(Icynene) has to be covered, because of its fire rating. It also soaks up water like a sponge. I'm not sure about the requirements for closed-cell (Urethane), but it will not absorb water, and you could use less. 1/2lb vs. 2 lb
@ December 1, 2013 3:54 PM in Which is my "C" wire, want to install a new Hoenywell RTH9580SR501-4 might even be cheaper, and has the 24v common.
@ November 30, 2013 1:02 PM in Maximizing efficiency of a mod con questionJust can't get my head around using a fixed pump on the primary, and DeltaT on the secondary. I understand the reason, and concepts of both, but keep seeing a competition to false modulation of the boiler, that may not reflect the needs of the system. The delta-t circ essentially causing the mod con to not respond correctly to the system.
It seems to me, that matched flow,primary and secondary is the way to go, and DeltaT is just the product of the conditions on the secondary side.I'm just a homeowner, and enjoy learning.
@ November 29, 2013 7:58 PM in need help with one pipe steam system,, rookie!Make him do everything over. It doesnt even look like the smoke-pipe is connected correctly. It looks like it's over the elbow.
@ November 29, 2013 1:22 PM in Gas Conversion/ Deteriorating Smoke PipeThe boiler was cleaned thoroughly..... T Gas= 520.5 T Air=78 O2=4.4% CO=5ppm CO2=9.2% Exc air=26% Efficiency=80.4% Losses=19.6% Delta T=442.4 Ref. O2=0.0% CO=6ppm
@ November 29, 2013 12:32 PM in Gas Conversion/ Deteriorating Smoke PipeThe chimney is centered in the house, and was re-lined. The boiler operated for 12 yrs, without a barometric damper, as was stated as acceptable in the I&O manual. There was never a problem with moisture. Since the change to the ez-gas and addition of the damper, the problem seems to be the worst below the damper.The boiler was down-fired approx. 25%, and is running at 150000 btu's.
@ November 28, 2013 10:32 PM in Gas Conversion/ Deteriorating Smoke PipeThanks Steamhead,
The chimney is capped, but there is moisture issues, and the guy that installed the burner noticed it as well when he fired it up the first time. He did down-fire the boiler, and I have a copy of the combustion analysis. I guess the question is, how much can you safely down-fire a series 8 -5 section, without causing problems?
@ November 28, 2013 10:17 PM in Gas Conversion/ Deteriorating Smoke PipeI had my Smith 8 series boiler converted with a Carlin ez-gas before last heating season. This year, I notice the smoke pipe between the boiler and chimney is deteriorating rather quickly. Is it possible something is not right, and causing this?
@ November 28, 2013 7:31 PM in Taco SR502 with Weil Mclain UltraTT refers to thermostat connections on a boiler. The U-Control red terminal block provides for 3 thermostat connections.
@ November 28, 2013 10:20 AM in Temp of Cast Iron RadiatorHave you bled all the radiators? With the cold we've had here in CT ( West Haven),your radiators should be getting hot. With my 90 yr old colonial, the thermostat placement is not very good anymore. There have been additions put on the house that now change the heat loss for the area. If you're having trouble getting the heat to the rooms farthest from the thermostat, try shutting off the valve to the radiator in the room with the thermostat. Oh....and thermostats behind and over a TV will really screw up the comfort in the rest of the house.The TV will keep that thermostat at around 72 degrees, while the rest of the house gets down to about 60. Just a thought.
@ November 27, 2013 5:41 PM in Oil to Gas conversion 2 pipe steam system low heatI was going to post the same link that BobC posted showing piping "Don'ts". Look closely, your current piping is in there, as a classic "Don't".
@ November 26, 2013 5:40 PM in Oil to Gas conversion 2 pipe steam system low heatNone of the steam guys here would drop a boiler in and run for the door, as it appears has been done in your case.The system has to be evaluated completely, before the new boiler is installed. They should have known what main vents were used. At 80 yrs old, the wet return should have been replaced, or flushed at the least. Did they match the new boiler to the total EDR of the radiators?
@ November 23, 2013 10:16 PM in Radiator Closest To Return Leaking A lot of WaterThose are minimum piping requirements. The object is to minimize velocity by making the riser and header as large as possible. Good practice would dictate that the header be at least one pipe size larger than the main(s). You want to get as much of the water out of the steam,before it enters the mains, as possible. You will pay extra in fuel costs, to push the water up, other-wise.I'd lose that system riser( with union), at the elbow. Come out of the boiler 3", nice and high. Then elbow back towards the smoke pipe, down to the header, and across to the equalizer. This gives you the offset you need to connect up to the existing main, and will provide, dry steam.
@ November 23, 2013 2:56 PM in Radiator Closest To Return Leaking A lot of WaterWhat size is that boiler?
@ November 23, 2013 11:28 AM in Radiator Closest To Return Leaking A lot of WaterNo reduction in pipe size coming out of the boiler in those illustrations.....very important detail.The details are important.
@ November 23, 2013 10:33 AM in Radiator Closest To Return Leaking A lot of WaterAll of the near-boiler piping needs to be correct.
@ November 22, 2013 9:44 PM in Radiator Closest To Return Leaking A lot of WaterThat configuration is going to give you some very wet steam. You have no header.It is not the cause of your bouncing water line, but you should correct it.
