Question

@ December 2, 2010 10:10 PM in Question

Its a Weil Mclain and is very old, at least 50 year old boiler don't know about the oil burner itself.

It does have a tankless coil that preheats the water some before it goes into my electric hot water heater in the winter when I run the boiler.

I had another post from a few months ago with pictures. http://www.heatinghelp.com/forum-thread/131656/50-year-old-oil-fired-boiler-question

Another thing is. Since I replaced the flow control valve, some pipes rattle and bang in the basement after they heat up and cool down. Could that be air in the pipes yet. I bleed all the radiators.

Thanks for your help.

My very old oil fired boiler has 2 adjustments. 1 for the boiler temp and 1 for the circulator. Is 180 for the boiler and 160 for the circulator good settings? I had them at 170/145 before and it wasn't warm enough.

Replaced valve and some pipe.

I replaced my flow control valve along with steel pipe. I then filled the system up with water and bleed the radiators. I had one small leak, drip from a steel 1.5 inch to 2.0 inch adapter that meets up to the valve. I had to tighten that adapter all the way with a big pipe wrench to stop that leak.

My question is: Can you over tighten a steel adapter like that? I pulled as hard as I could until I couldn't turn it anymore and the leak stopped. Its not leaking anymore, just wondering if it will be ok being that tight? I hate to drain the whole system and take it all apart again.

Thanks

I'm located in PA. I am having a professional look at it when I get it cleaned before winter. I may check into a new system next year. I just need to fix that flow control valve first.

Thanks for all the replys.

Here is an attached file of what my boiler system looks like. The circulator only turns on if it calls for heat. The boiler heats the water up to a set temp and then shuts off when it reaches that temp. The temp gauge to the boiler does not work but the last tech that was here said the boxes that set the temp on the pipes work. For some reason it is connected to my electric hot water heater, I'm guessing it just preheats the water for the water heater when I use the boiler in the winter.

50+ year old oil fired boiler question

@ August 25, 2010 10:03 PM in 50+ year old oil fired boiler question

I bought a house 2 years ago with a very old Weil Mclain oil fired boiler. The oil burner isn't that old but the boiler system is. My problem is that after it circulates and shuts off, it seems like the Thrush Flow control Valve sticks open. Here is a link to what valve I have: http://www.heatinghelp.com/files/articles/1229/221.pdf

Anyway it seems to stick open and gravity feeds to a few of the cast iron radiators upstairs and gets very hot. I then have to open and close the lever on the valve a few times, I hear something drop inside of it when I do that. Then it stops gravity feeding until heat is called and the circulator runs and stops again.

Question is, do you think my Thrush Flow control valve is bad and needs replaced or is it something else causing it not to close by itself? Also, where can I buy a new similar valve like that? It has a copper pipe attached to the back side of it for the old steel expansion tank so I would need a valve that I can attach that to it too.

I would just like to replace the whole thing with a new one but its not in my budget right now so I have to keep this one going for now. Any advice is appreciated. Thank you
