That is a very nice setup. Baby boiler that could easily heat more, Power vent so no chimney needed, PEX to run throughout the house, perfect in my world. Wished there was this available 22 years ago when I put my system in. Does that supply your domestic hot water also? From a deep freeze to rain here and much weirder warmer temps for January. Suppose all the melting snow will be glare ice AGAIN.
