"I had to replace my old boiler heat as it was not repairable. So I purchased a NEW wall-mounted, modulating gas, condensing, combination Boiler. It replaces BOTH my boiler heater & Hot water tank. The new unit is attached up on wall with a small tank, gas, water lines below. The 2nd pic is where old hot water heater used to sit. Now I have all that extra storage space!! And no need for upkeep & repairs on a big old hot water heater!! The only thing I can complain about was that they were here for 12 hrs!! start to finish. Plus I was here sitting practically on top of a space heater dressed very warmly all day. And of course this was in January 2025 in northwest Indiana. I think this was a 1st time install for them in an older home not a new build. I would have rated them as a 5 star if not for the LONG DAY it took to be installed. They all were very nice, kind & cleaned up their mess. They brought large painter cloths to put down on floors due to going in out in the snow also."
