Can Taco VT2218 Circ Supply-Return Temp Probes Be Taped To Pipes?
Due to swapping of VR 1816 and VT2218 circs, finding a well to insert the probe wires on the return is problematic without taking apart piping and putting in a well. Can the return wires just be taped onto the black pipe and give a relatively accurate reading? (We're hoping the run the circ in ∆T mode for the DHW.)
