Yes its a Extrol bladder #30 tank. I'll try upgrading to a #60 tank and see what happens. I really do appreciate your response. Yes its a Extrol bladder #30 tank.

Either your existing expansion tank is not set up correctly or it is not big enough for your system. You did not mention what type of expansion tank you have. Most likely it is a bladder tank. It needs to be installed and set up IAW the manufacturers instructions. If it is installed and set up properly and you still have over pressure problems when your system heats up you need to add more expansion volume, you can add an additional tank. Make sure that makeup water is not leaking into your system causing the over pressure problem. Hope this helps! Jay I. Hoar Service Manager www.mckenziecorp.com Hi Andy,

The pressure in the boiler slowly climbs to 25-30 PSI when firing up to the 180 degree temperature the aquastat is set for(this happens even with the water turned off to the boiler). I let out an inch of water in a 5 gallon bucket which lowers the boiler pressure to 15 PSI. but when I come back the next day the boiler climbs back up to 25-30 PSI. (it once climbed to 35 PSI when the boiler overran to 210 degrees in the winter and leaked through my expansion tank seam) I replaced the boiler feed valve(I even re-adjusted it for lower than 12 PSI when boiler is cold), the #30 expansion tank, the air relief valve, the pressure relief valve, the hot water coil, I've purge the air from the system. My house is 2 floors @2200 square feet. I didnt always have this problem. a couple of years ago I added 20 feet of new baseboard. Do I need a bigger expansion tank? What size? I dont know what else it could be. Thank You I have a problem with my 12 year old Burnham RS-110 boiler that is driving me CRAZY.

We are glad you like it! Now, to answer your question... If your burner is as old as your boiler (Vintage 1999) we think you would be better off buying a new burner. The controls that are on your existing burner are, no doubt, obsolete by today's standards. Maybe the Gordon Piatt Model R burner would be a good replacement. http://www.johnzink.com/products/burners/pdfs/broch_gp_model_r.pdf Contact your local Gordon Piatt sales representative to get a price on a new burner and to discuss your switch from oil to gas. Use this link to find the G-P rep closest to you - http://www.johnzink.com/products/burners/html_gp/burn_gp_sales.htm Please let us know what you decided and thanks again for your post. Dear Ladd,

If you have a sectional cast iron boiler, the cracked section can be removed and replaced. This would allow you to repair what you have without buying a complete new boiler. Here is a link to a Weil McLain Boiler parts sheet that shows the sections I mentioned above - http://www.weil-mclain.com/professionals/services/current/cgi.pdf Maybe if we knew the manufacturer of your boiler we could help you with additional information.
