@ April 17, 2014 11:46 AM in Modifications to Hydronic Systemnow I recall your earlier posts. 15ºC is just fine for the boiler, but I would still do a heat loss calculation before you assume the boiler does not need a buffer tank.
@ April 16, 2014 10:09 AM in Modifications to Hydronic SystemOptimal sizing will deliver full valve authority, which is critical in mixing applications. We usually aim for a pressure drop of about 4 PSI across the valve at full flow (translation: GPM = 2 x Cv.)
A few more basic questions: Why are you assuming 15ºF ∆T on the boiler? What is the design day heat loss for the structure? Does the boiler have sufficient water volume without adding a buffer tank?

Tap on the expansion tank with a screwdriver handle. What kind of sound does it make?

@ April 14, 2014 11:12 AM in Boiler pressure risingHave you checked the expansion tank?

Government intervention is a big part of what got us in the mess we're in with our farming operations. Like so many other things, retail milk prices do not even come close to reflecting the real costs involved.

@ April 12, 2014 2:29 PM in who is this Mr Pex guyis PEX-A, good stuff, and a good company to deal with. We use it with Uponor F1960 EP fittings.
@ April 10, 2014 10:40 AM in Is my steam boiler way oversized?is in West Virginia. Don't recall any pros hailing from those parts posting here, but I haven't been around all that long.
"Nearest dealer" is pretty much a crapshoot. Better to find someone with proper conversion burner training, hopefully with some steam background. Tim McElwain might have someone he can refer.
@ April 10, 2014 10:24 AM in Recirc Lineshould probably be mandatory, but the devil would definitely be in the details as far as implementation. This probably deserves its own post in the Codes forum.
@ April 10, 2014 10:18 AM in Tub strainer removalhad to go look that one up https://www.ridgid.com/us/en/one-handed-recip-saw Kind of like a Hackzall with more grunt. I like it.
@ April 9, 2014 12:37 PM in Is my steam boiler way oversized?be able to remove some sections when the repipe is being done, and end up with a V-905 when you're done.
Installing a smaller oil burner will cost almost as much as a NG conversion burner would.
@ April 9, 2014 11:45 AM in Controls cabinetDon't seem to come at the nice prices, and the shipping can get to be rather pricey as well. Used/surplus maybe?
@ April 8, 2014 10:43 PM in Is my steam boiler way oversized?V908 is rated for 2,888 square feet of EDR. You have 1,433. Your boiler is twice the size it needs to be.
@ April 8, 2014 10:31 PM in Ratings for old Modine convectorsfound that online this afternoon, definitely useful info there -- especially the derating tables. Still hoping to find data on these 9" 5-tube designs if I can.
