But the thing I don't understand is why he said this:
, the smaller the plumbing , 1 ½â€, the more pressure and the faster the water flows through the heater
Smaller plumbing reduces flow rate not increases it. The velocity of the water is higher in the PVC pipe but not the heater.
I'm with you - I don't agree. And told the tech that when I was on the phone w/him. I'm willing to do the work (and, if I can convince the customer, re-plumb most of the pad) and then call the tech back if it blows up and doesn't work.
Here's a shot I took while I was out there yesterday - don't laugh too hard (and I want to stress... I didn't plumb this):
