@ June 7, 2013 5:40 PM in 1940ish boilerThis boiler hasn't worked in a year. They went through this past winter by using the alcohol heating method. Drink more beer and you'll be fine. So I did not fire it. And to top it off there is a leak somewhere in the crawl that we need to find and see how bad it is before we consider the new boiler.
Oh, getting up and going to work every day is such a "I wonder what will happen today to make things interesting" life.
@ June 7, 2013 6:38 AM in 1940ish boilerYou're kidding, right? This is a frat house. I doubt this thing has been looked at once in the past 10 to 15 years. maybe. And since the fill and drain were also plugged solid we know that even if they were showing up they sure didn't drain anything.
@ June 7, 2013 6:35 AM in 1940ish boilerit's a closed syste. And since the feed was tied into the bottom rear of the boiler it was also plugged solid. As was the drain. It was fun getting the system drained down, I'll tell you that.
@ June 6, 2013 9:56 PM in 1940ish boilerStarted a boiler replacement, after waiting a week for asbestos removal. It's a 9 section National hot water boiler. We popped the sections and this is what the return passages looked like. They both looked like this. i wonder just how much flow there was really going on here.
@ December 29, 2012 10:17 AM in Old Boiler...leaky expansion tankhow and where you mount the new #60. If the baldder in that thing ever ruptures and the tank gets water logged it will weigh about 72 pounds. Don't just hang it off a pipe. Use a bracket or something and mount it to a wall. They're supposed to be mounted vertically.
@ December 1, 2012 3:33 PM in Interesting dilemahave a restriction. 5 of them as a matter of fact. 5 monoflo tees with plugs in them. There are no valves except for ball valves. There is a B&G flow control but I manually opened it. Main heats relatively quickly considering the circumstances. No zone valves.
I've emailed the GC and told him we need to repipe this. We'll see what happens.
@ December 1, 2012 11:04 AM in Interesting dilemaMultiple boiler control. Has outdoor reset built in. Don't remember the number but I do remember I started using them fairly early on when they opened for business. So maybe we are not talking 30 years but it's damn close. I seem to remember Tekmar entered the scene in 83 or 84. Control still works fine. Either that or I added it at a slightly later date. I don't remember. I really don't have that many brain cells left. Sniffing too much primer and glue in my life.
That's my story and I'm sticking to it
@ December 1, 2012 10:52 AM in Interesting dilemaYou always have to be aware of potential air traps.
@ December 1, 2012 10:17 AM in Interesting dilemaIf you read my post you will see I mentioned I had done exactly that 25 years ago to a radiator connection on that loop. Question that was being asked was whether people felt if you cap enough connections off without installing a jumper it would stop flow to remaining rads altogether.
@ November 30, 2012 5:34 PM in Interesting dilemaWas at a job today where we were hired to remove a cast iron rad so they could renovate. While we were at it owner had us replace the rad with one slightly smaller. Renovation is done so we connected it up and tried to fire it up today. The entire zone has no flow. (Technically we don't know if it had flow before we started this project).
Now..... some history. I replaced the boiler almost 30 years ago when I was working for a large company. At the time I was head of the hydronics dept. We installed 2 boilers. Primary/secondary. 6 zones. Cast iron radiation. Monoflo piping. Outdoor reset. I remember that the last time I was there 25+ years ago, everything worked fine.
The zone in question is original to the house. 1-1/4" steel with B&G venturi tees. Tees on the return of the rads. I have confirmed many times over it's not air. There are no high points in the piping. Dedicated risers off the main straight to the 2nd floor to each rad. Assumed it was a circulator issue. Replaced it today. No difference. No flow in any of rads. Got to following the main. By the way, the main is hot as hell. As I follow it around I see a set of tees where a rad was removed. We did it 30 years ago and the 2 tees are connected together with a jumper pipe. However, as I follow the main around I see 5 sets of tees where rads have been removed and installed onto a new loop to make a seperate zone. The old rad hookups are just capped. So now this 1-1/4" main only has 3 rads connected to it and it runs all the way around a large portion of the basement. Even though the 3 rads are right near the boiler they left the entire main and capped the pipes.
So the only thing I can come up with is the capped venturi tees are affecting the flow so much I am not getting any up to the rads that are still connected. By the way, when I replaced the circ (which was a Taco 0010) I first tried a 3-speed 0010 and then tried a 3-speed 00R. Neither pumping characteristic made a difference.
@ November 18, 2012 8:43 AM in Unknown wall radAnyone happen to know who made cast iron wall rad? I need to find ratings.
@ September 8, 2012 5:43 PM in Check out this new productMay Supply's Fall Harvest event they have in Harrisonburg with a booth too. I think it's Sept 21. I think May is offering specials on everything, including a discount on HydroClaw's. But you would need to check with them.
This guy needs to be introduced to a HydroClaw. It's an actual job we were on.
@ September 6, 2012 8:54 PM in Check out this new productWe both appreciate you mentioning us. Anyone have any questions just email me.
@ May 18, 2012 2:40 PM in Threaded venturi teesAnyone know of a company that still makes threaded venturi tees? I only see copper available. If not, anyone have a couple of 1-1/4 x 1/2 or 3/4 they are looking to sell?
@ February 5, 2012 3:00 PM in Copper ceiling radiantif I get the job. Then I can light up the basement and take some. There are coin vent bleeds in closets where they ran soft 1/8" tubing off the top of the distribution and bent them down so they are below the closet ceilings. Only piping we can even see is the immediate boiler piping as once it leaves the Sarcotherm mixing valve it disappears up into the ceiling. Even the boiler room ceiling in this place is finished.
Probably going to change the boiler piping to give them working isolation valves and a Tekmar outdoor reset control and motorized 4-way valve. And the 4-way will give us boiler protection too, which it doesn't have. And some thermometers.
@ February 5, 2012 11:37 AM in Copper ceiling radiantThere is nothing on the floor above each radiant ceiling. Every door, access and nook and cranny was looked at. We even looked inside the dumb-waiter chase and there is nothing. Only thing accessible is the purge drains and key vents attached to soft tubing coming thru the ceilings of closets to bleed everthing. And the original mech drawings show no above the floor stuff. There isn't anything else we can do nor that the owner or contractor want done.
Nice thought though.
@ February 5, 2012 9:26 AM in Copper ceiling radiantConcrete floors on metal trusses above. And definitely metal mesh with plaster going back. No sheetrock.
@ February 5, 2012 9:24 AM in Copper ceiling radiantConcrete floors on metal trusses above all radiant ceilings. Not opening anything else up except the 2 rooms. No interest, or money, to zone. 4 zones now, one for each floor and new owners are happy with that. As far as anyone is aware, there have been no failures in this system to this point.
@ February 5, 2012 9:15 AM in Copper ceiling radiantis why they want to go back original. The concern is the PEX will not perform the same. Or expand and contract the same. We have 60+ years with this. Don't argue with success. I will be interested to see exactly how it is attached. The construction of the house is metal trusses with concrete on all 3 floors. And since they are only renovating the 2 rooms we are not going to change anything else like zoning. One thing I will be able to potentially do is rebuild the boiler piping. The old original Sarcotherm mixing valve is still there. God only knows if it's still working. Probably not. And around here, for some reason, the old contractors used the old square head gascocks as valves and 99% of the time you couldn't turn them if you had to.
Here's a relatively bad pic of the boiler piping and another of the mixing valve. Sorry about quality. No light and a phone camera.
