: One heat exchanger in 20 years for a boiler is a good record. Hydrotherm is now manufacturing an improved version of the Hydropulse; but several other major manufacturers now have high efficiency boilers that do not pulse and are quiet. See Munchkin, Weil-McLain Ultra, and Monitor.
My hydropulse is also 20 years old and I found out how to clean it and determine if the spark plug is working correctly. It is still literally humming along.
