@ April 13, 2006 9:20 AM in weil-mclain seal issue

Many Wallies have been to the foundry in Indiana. There was about 50 or so when I was there a couple years ago when Wetstock was in Chicago. Is the foundry staying put and are all the boiler castings for all your products lines going to still be made there or are they moving some or all production to China? Boilerpro

Long term success, short term success and Knuckleheads

@ April 12, 2006 9:18 AM in weil-mclain seal issue

A standing back perspective, IMHO As many have already said here, O rings are alot easier to put together without having leaks initially (is this the reduced failure rate cited in the WM literature?), but does that necessarily make them the better long term solution? I doubt anyone will diagree that it is alot easier to screw up a nipple installation (whether steel or iron nipples) and get leaks initially, but what about long term leaks? With the WM's I have seen here in northern IL, the factory assembled CG series boiler seem to hold up very well, however, the usually site assembled EG, EGH rarely last more that that 16 to 19 years mentioned previousily....probably an indication of knucklehead installation...ie improperly installed rope seals etc. I have not seen this high of a failure rate on the larger weil MGB/LGb boilers, but the guys installing these usually have had more boiler experience than the typically untrained forced air contractors that are installing the EG,EGH series. (I'd say about 95% of the boilers installed in my area are installed by forced air contractors or plumbing contractors with no training). To me it appears that one of the chief reasons for seal failures on Weils is that a large number of contractors that install the boilers are not properly trained and/or are the low ball bidder....those types that never will spend the time or money on proper training or reading the installation manual. For them they can slap in an O ring seal boiler and have no leaks, despite shoddy work, where if they tried that with a nipple assembly boiler, they would more hours invested and have leaks right off the bat and, of course, blame the boiler. However, a few years down the road, the O-ring, site assembled boiler is leaking due to the shoddy work and probably lack of proper maintenace to boot. Until we can get rid of the shoddy installer, the O rings will keep failing giving all O ring manufactureers a bad name and the reputable installers that use thier products. As for myself, I will still stick to Burnhams, Slantfins, and Dunkirks for the decreasing numbers of cast iron sectionals I am installing. 150 years of proven longevity with push nipples is hard to argue with.

You won't be disappointed

@ April 10, 2006 9:05 AM in Future Prestige

and you'll only be recieving the tip of the iceburg on what the control can do. That's a sweet combo package. I hope its here soon, I already have people looking at other combos versus the prestige with seperate indirect. However, I bet they will be disappointed when the fresh water side of the plate heat exchanger plugs up. Boilerpro

Another thing that may be a problem

@ April 8, 2006 2:26 PM in Critique wanted

I suspect that gas meter is undersized for the load of the two boilers..unless you're running higher pressures. Meters that size usually top out at about 425 cu ft/hr. @ 0.5 inch pressure drop. Gee, you make me feel pretty good, I been told I don't know what I'm talking about by other "contrators'" too, when I come across new steamers that are twice as big as the radiation. Sounds like you're up and running....just don't go too fast yet! Boilerpro

My simple

@ April 5, 2006 6:04 PM in boiler protection options

Is to pipe P/s and install a Danfoss Esbe Thermix Valve on the boiler return. This setup enusre full flow through the sytem during bypass and requires no wiring.... The valve is self actuating like TRV's. Boilerpro

Check out Slantfin

@ April 3, 2006 11:52 PM in Tiny boiler

I think they have some little gas fired models Boilerpro

I have several Suspended systems

@ April 2, 2006 4:03 PM in Pex clips and wood floors

with Wood floors above and they work just fine. As Tim said whether this will work for you depends on many conditions....The only way to find out is to run the information through a design program. I keep the water temp below 140F and can heat most spaces in properly insulated homes this way. Lots of glass, air lekage or low R-values requires additional capacity which plates can provide. Boilerpro

Highly recommended

@ March 31, 2006 8:48 AM in Just did The Advanced Prestige Training Yesterday....Boilerpro

The more I know about these boilers, the more I like them. 429 Stainless instead of 316 All welded heat exchanger, no O rings or sealants needed. P/S not necessary on all installations, due to low pressure drop in heat exchanger. Modulation is PID controlled for more stability versus proportional only control. Modulation is full, not in steps. Can run down to about 1% O2 and remain stable Can Be used with setback thermostats due to control operation. Reset curve can be adjusted to a nearly infinite variety of configurations within the hi and low limit points so you don't have to just a pick a curve that seems closest. Resembles tekmar in flexibility, with a tighter band of extremes. Standard typical repair parts across the different sizes. NTC sensor input available for DHW indirect. Control of external mix valve for two temp systems (to come) They've also added the MINIsmart that provides 3GPM at 70F rise so there is now a low cost sidearm available for installations that are budget tight. There is also more to come on the control I've got 4 in now without any problems and others here have alot in with no problems. We may have a condensor here that harkens back to cast iron in terms of robustness, reliablity, and life expectancy, at a competitive price. Boilerpro

I'd be worried

@ March 31, 2006 8:18 AM in Moisture damage from venting?

I have never worked with a BAxi, but I don't know of any other manufacturer that would allow this vent location. Usually minimum space is several feet from an inside corner. Codes may frown upon this too. Boilerpro

I have seen that!

@ March 27, 2006 8:12 AM in Can copper pipes be installed with a steam boiler?

Looked at a 4 year old LGB with two risers in a welded header and the gaskets were already starting to leak. The boiler had been short cycling for awhile due to the installation of too small of a transformer, so that only accelerated the problem. Boilerpro

Glad to hear all is going well!

Isn't that Ken's installation method

@ March 26, 2006 8:06 PM in copper staple up

He used copper exclusively, didn't he? Boilerpro

But....

@ March 26, 2006 8:00 PM in too much venting?

How about corrosion issues of not venting all the air in the mains? I've had this question for a long time about not venting beyond the last radiator. Boilerpro

Also, I wonder about life......

@ March 25, 2006 10:06 AM in Can copper pipes be installed with a steam boiler?

What king of strength do you have in copper when there are problems like water hammer and I wonder how long the o rings will last at 215F temperature with constant movement. Boilerpro

40 in a week or so

@ March 18, 2006 8:47 PM in Ultra 310 x 8=2480?

How did the cost of doing 8 of those compare to doing a couple (or one) of the Big Veissman condensors? Very Nice install!!!! Boilerpro

Brad may be right....

Policies

@ March 17, 2006 8:11 AM in What are your policies regarding High CO?......Boilerpro

I find about a third of older cast iron burner atmospheric draft hood equipped gas fired boilers have high CO (700 to 2400PPM) Most can be brought down to about 225PPM with just a slight change in input. However, on those units that won't clean up, what do you do, assuming all else is OK? Under what circumstances do you "pull the plug"? Boilerpro

1.0 is the standard

@ March 17, 2006 8:03 AM in what is the formula for cement btu's compared to water btu's

so all specific heat numbers are proportional to that. From Mr. Silberstein's post, that would put concrete at 15.6 % of the capacity of water. Marble 21% steel and iron 11%. Water is a pretty amazing material, isn't it! Carries nearly ten times the amount of heat per pound when compared to steel. And converting it to steam makes it even more powerful! BTW... 6 years in a Architecture School and can't draw a straight line.....I know your feeling! Boilerpro

Are you sure, Brad

@ March 17, 2006 7:54 AM in what is the formula for cement btu's compared to water btu's

that sounds really high. I don't have the specific heat for concrete, but marble is only .21, steel and iron .11 Boilerpro

What I am seeing here.....

@ March 15, 2006 9:04 AM in Relationship between CO and Efficiency...Boilerpro

is that we all have a huge amount still to learn about combustion. Sort of like our recent heat loss calc discussion. I work only with gas,so that is my area of experience. I agree that high CO is a symtom, and yes high CO can result from both excessive air or not enough air. I had a Burnham steamer with a Gordon Piatt power burner recently that had a CO reading of 4500 PPM and about 300% excess air...very high O2. We cut down the air and the CO dropped like a rock....i suspect the excess air was cooling the flame so much it could not burn properly(very low NO). Efficiency jumped from about 68% to about 83%. NO sooting goin on. At about the same time I had a little conversion burner in a 50 year old 2 pass Kewanee with about 300% excess air and CO under 100PPM, we cut the air to about 100% and CO only dropped slightly, But efficiency on the meter jumped from 68% to 81%. Unit appears to still be underfired, but couldn't get anymore input out of the ancient burner. I have found about a third of the older atmoshperic boilers I test(almost always if not always with cast iron burners) come up with High CO...From 700PPM to 2400PPM. None have shown signs of sooting. Usually a slight reduction in input brings the CO down nicely. Typically these older models seem to work at 30% excess air and about 200PPM CO. Newer models seem to run about 50% excess air and about 30 to 50PPM CO. This may explain why older atmoshperics had less trouble in gravity conversions with no low temp protection than newer models....they are less likely to condense at such low excess air numbers. Let's keep this going! Like Mark said Yearnin' for learnin'.... Boilerpro
