Amtrol BoilerMate PI Series Indirect (Stainless Coil) Review
The Amtrol BoilerMate PI Series Indirect (Stainless Coil) is Amtrol's premium indirect water heater line with stainless steel coil heat exchanger upgrade. Available in 40, 60, and 80-gallon capacities.
Specs: stainless steel internal coil heat exchanger (versus standard copper or glass-lined steel in basic BoilerMate WHS line), polyurethane foam insulation. Compatible with most US residential boilers. 10-year tank warranty (longer than standard 7-year WHS line).
The PI Series premium positioning targets buyers wanting better corrosion resistance and longer service life than the standard BoilerMate line. The stainless coil heat exchanger extends service life beyond the typical copper-coil indirect failure mode.
About $1,800-$2,400 unit depending on capacity, $2,800-$3,800 installed. Right buyer: home with hydronic boiler wanting indirect DHW upgrade beyond standard BoilerMate engineering.
