this is my supply header,expansion tank, air scoop, vent, cold water make up and also two amtrol hot water tanks 42 gallon eachreturn header with 10 zones for heat and 1 zone for the hot water makermy plans are to put a T into the supply just above that green handled ball valve. then i would put a 2 inch ball valve and conect to one of the 75 foot runs of 2 inch black iron i have already run. this picture shows the return to the oil boiler and the piece i want to install . and on top of that valve pointing up would be the circulation pump then continue to that other 75 foot run. wish me luck breaking into this line... they put it together in the 40'sa naked DF 52018 tons of rice ready to burn
i am looking for the best way to plumb this boiler let me start a couple of questions :... do i pipe the supply of the coal boiler to the return of the oil boiler? to i need any check valves? how do i size my circulation pump? and what about the bypass thing? if i do need one what size line do i use if i am running 2 inch supply and return?
some things i am ok with are:
a dump zone
another expansion tank
air scoop with vent
sorry for being so long thanks in advance and dont worry about my feelings give it to me strait.
