Ultra Oil multi temp piping
I have been tasked with correcting a job that someone else has done. What I have I a Weil-Mclain Ultra Oil boiler. It is piped with a supply and return manifold. It has several hi temp zones and several radiant zones. What I do not know is can an UltraOil boiler be piped with primary and secondary loops and work efficiently or is there a better suggestion. The reason for this job is the radiant part is piped incorrectly, looks messy and the customer wants it moved.
