@ November 24, 2013 7:15 PM in Radiator shut off valve and boiler sight glassI would advise you to keep the radiators on even if you don't use the rooms. A cold room will only make the other rooms colder, and run the boiler longer. Plus, with radiators shut off, the boiler will be grossly oversized, causing short cycling, wet steam, and extra wear on parts.
The boiler should be drained a few cups every week. If the water is clean, go every 2 weeks. When you refill the boiler, run it long enough to make steam to boil out all of the fresh water's extra oxygen. The sight glass can be removed and cleaned.
@ November 24, 2013 6:42 PM in New steam boilerHeaders should never be welded unless you add a lot of threaded fittings to allow for expansion and twisting.
Turn that pressure down! Why 4?
That header is an "automatic boiler splitter".
@ November 23, 2013 7:25 PM in Smith becomes WestcastThe 21st century has not been good to Smith. I think the series 8 as we know it is gone forever. They've said that the newer model will be a few points more efficient. If it's the same as the Peerless WBV/WV, then that's just not true.
@ November 23, 2013 7:52 AM in Smith becomes WestcastI guess the Smith/Peerless tie is officially sealed. Let's see what happens to the product line now...
@ November 23, 2013 7:36 AM in how to wire a vaporstat in series with presure controlLet's assume that the controls are exactly the way they came from the factory. After you install the Vaporstat, run a wire from it to the existing Pressuretrol. Take one wire off of the P-trol terminal. Wire nut that wire to one wire from the V-stat. The other wire from the V-stat goes to the P-trol terminal.
Think about series wiring as completing a circle.
@ November 23, 2013 7:34 AM in help with adding steam mian ventsI never liked the idea of tapping a piece of pipe or fitting. We always see them leaking at some point. I would try to get real fittings on the mains to add the vents. It'll be a lot less prone to leaks, and lot easier to add additional vents in the future, if needed.
@ November 22, 2013 8:58 PM in Radiator Closest To Return Leaking A lot of WaterSometimes, two problems can mask each other. Maybe with the weather being mild, the boiler never cycled long enough to cause any problems.
@ November 22, 2013 6:47 PM in Smith becomes WestcastThe new series 8HE looks oddly familiar...
@ November 22, 2013 10:07 AM in Vaporstat & Gauge Piping with drip leg?Try to install the pressure assembly on top of the boiler. You'll have room for a drip leg there.
@ November 21, 2013 8:30 PM in Steam ghostWho ya' gonna call?
Methinks that ghost has aa name,,,Wet Steam. Or maybe his brother, Sagging Main.
@ November 19, 2013 8:39 PM in Is there a truly graphical heat-loss program?Wrightsoft! You draw the blueprints and change your parameters. Easy, peasy, lemon squeezy.
@ November 19, 2013 8:35 PM in My Shiny Old ToyThe trap looks like a band-aid for keeping steam out of a dry return, instead of dropping into a wet return.
I've seen the "bypass, short circuit" arrangement once before. It had no appreciable effect on the system. Although, when I saw it, there was a cross below every radiator run out.
The spigot is another band-aid. Somebody didn't know how to use a level, and the spigot is their way of removing water from the main.
@ November 19, 2013 7:39 AM in Another Twin System - 6" Drop HeaderThe lag boiler cuts out at 12. Lead boiler cuts out at 16. When both boilers run, it builds pressure steadily, and maintains system very well. When only the lead boiler runs, it doesn't maintain enough pressure to keep the unit heaters running.
I'm planning to go back soon to add modulating fan controls to the unit heaters (as recommended by SWEI). If the blowers run at 50% speed, they should more closely match the lead boiler's output.
@ November 17, 2013 8:30 PM in Another Twin System - 6" Drop HeaderYou're right that it will. However, we needed to keep the Gifford Loop high enough to keep all of the wet returns wet. There is also about 2 cups of water that lays inside of each tee. In fact, every header, no matter what size, has water trapped in the fittings.
@ November 17, 2013 7:48 PM in Another Twin System - 6" Drop HeaderWe were out of wicking, or else we would have used it. The last 6" 90 faces down at a 45 degree angle, and reduces down, going to the equalizer in the back left. There is surprisingly little steam carryover between boilers.
@ November 17, 2013 4:17 PM in Another Twin System - 6" Drop HeaderThose are for the circulated zone. The water level in the boilers equalizes because the returns are connected.
@ November 17, 2013 6:04 AM in Smith G-8 with New Style Carlin EZ-GasCheck out the Honeywell R8845U relay. It has a Common terminal for the WiFi thermostats and a control fuse.
@ November 16, 2013 6:56 PM in Another Twin System - 6" Drop HeaderSo, I spent the afternoon skimming and testing. Here's what I'm seeing...
The staging and unit heater controls are very fickle and hard to fine tune. I'm going to scrap the Vaporstats for pipe-thermostats to control the heaters. I will also set up another relay to turn off 2 of the 4 units heaters when the 2nd stage boiler reaches pressure and shuts down. The idea is that when 2nd stage isn't needed, neither is the full capacity of 4 unit heaters. In a sense, I will be modulating the heat emitters as well as the heat source.
More to come as I play around with this system.
@ November 15, 2013 8:23 PM in Another Twin System - 6" Drop HeaderI refuse to weld a header. I'd much rather struggle with threaded fittings than have a rigid header that's going to stress out and bust open in the future. We have 36" chain wrenches that just barely fit 6" fittings. A 5ft pipe wrench is on our wish list.
@ November 15, 2013 8:02 PM in Another Twin System - 6" Drop HeaderThe 6" fittings really kicked our butts. Embarassingly, we had a few leaks from being too conservtive with our teflon/dope. We remade the fittings by using dope, teflon, and more dope. The big threads of the 6" pipe digs deep and tears up all of the teflon tape. Lesson learned!
The system still needs some fine tuning and plenty of skimming. I'm debating whether or not to remove the Vaporstats on the unit heaters and install temperature controllers.
@ November 15, 2013 7:27 PM in Another Twin System - 6" Drop HeaderHere's the new system.
Steamhead, it was a Becket. I'll check what model number tomorrow.
