Oil piping

JimGPE_3

I need to pipe up an oil-fired furnace, a small boiler for an in-floor radiant heat system and two unit heaters. It has been a while! Any good sources for piping information out there, including piping materials and methods, pipe sizing, return lines, day tanks and the like? As you can see by my name, I am an engineer, so I am drawing this system for contractors to bid.



Thanks!

piping schematics

Jim, most manufacturers provide piping diagrams for their equipment, and NFPA codes would giv eyou information on how to pipe fuel lines, or you could hire a licensed guy to show you how its done.

Good luck.

Hight Matters

If the fuel pump units are over twelve feet from the bottom of the tank you need to look into pumping the oil up to the units .. Either using a day tank or pressurized lines .. I prefer a day tank for safety concerns .. Pressure against the pump seals are a concern if the oil is stored 12' higher then the pump or with pressurized lines . A Oil Safety valve , needs to be added before the pump ...



With Piping a day tank burner supply lines, air is a concern . a good downward pitch is preferred but sometimes not possible on long lines . A Tiger loop can be added to keep the burner primed,but its recommended to be higher the the oil supply . You need to size the supply lines to the GPH of the unit and length of the lines .. Also the the GPH output of the lift pump needs to exceed the input of all the units .. The return of the lift pump should end on the top of the tank with a downward pitch to the tank ..
