I heat my home, and get domestic hot water, with a propane fired Munchkin 80M boiler with a 45 gallon Superstor indirect tank. I have radiant floors which draw the heated water out of the Superstor via an injection pump with an outdoor sensor to control flow. The Munchkin only heats the water in the Superstor. System has worked well over the years. Unfortunately, the boiler has failed and is out of warranty so I am considering 2 different options: (1) replace the boiler and reusing the Superstor or (2) replace the Superstor and boiler with a high efficiency condensing water heater (Polaris). Which setup would you choose? I am especially interested in reliability and lifespan expectations as well as cost to operate.
