IMO. You are pumping at the PONPC, if both circs run at once they are in paralell, doubling the gpm, and as you indicated you're flowing through an unfired boiler aka a cooling tower :)

The very best way would be a P/S, but it would be major repiping. Then you could have either or boilers firing, the pumps sized and working correctly, hydraulicly seperated, and pumping away from the PONPC.

With a few setpoint controls the backup oil fired could come on automatically if the fire went out.

Depending on the wood boiler output, a dump zone or buffer may be needed. That's the intent of that zone valve above the wood boiler. Or I suppose you could pump through the unfired oil boiler to shed some excess energy from the wood boiler in an over heat condition.

Wood Boiler Piping

I'm trying to get a 20 year old Kerr wood boiler online that has never worked properly. The company's web site had a diagram similar to the one I posted. It looks like they want to use the oil fired boiler as a buffer tank. It is currently piped, almost like the diagram. Is it O.K. to send the wood boiler heat, through an unfired oil boiler? The electric controls are setup for this piping arrangement also. They also have a pressure relief valve, not a temperature and pressure relief valve, with the drain piped into the fire box. I guess to put out the fire? Would I be able to add a Superstor later to the wood boiler? Any thoughts or comments? Thanks, Bob Gagnon

I think that that is a good set up IF the oil boiler has a domestic coil,you are esentially heating your primary source of heat with wood instead of oil. I might prefer to move the oil circ. to the supply side though,after the comp. tank. For a cold start system(indirect water heater)I use a whole different approach. Butt the two manifolds together using flochecks so that each system works independantly of each other with an interlock so that the burner cannot run if the wood side is up to temp and running thereby not using the oil side as a heat sink.I can rattle on so if you have questions get back to me
