Title: install questions
Post by: cdie on February 20, 2014, 01:16:18 PM

Finances made me buy  used and found a glenwood 1250 boiler with +/- 50' of 1" Pipe snaking thru firebox and 9 gal tank on top of unit.  Installing in a shed 10' from the house. 20' of crawlspace and 15' more to the  oil boiler.  Unit has 2 3/4" inlets and a n 1 1/4" outlet.. existing boiler  is 1 pump with 2 zone valves. 1 is 15' from pump, other is35'.  What size line from boiler to boiler? Do i need to pump from b to b?  Thanks

I would look at your BTU requirement and what 3/4", 1" and 1.25" are each capable of.  I personally would run as large of line as I could get and afford, and run that between the 2 boilers. 

In regards to the statement about pump(s), not sure exactly how your system is setup, but you will need something to move the water  ;D

Have you thought about proper, non powered dump zones and adding more expansion tank, if not you are begging for trouble!

Your local glenwood dealer would probably best be able and willing to help you.
Good Luck!!!
