I built my house two years ago and went with the waterfurnace envision and also elected to go with the rinnia tankless water heater with 50 gallon storage tank. Close to the house completion the inspector decided that he did not like the desuperheater technology and ordered it disconnected. The plumbers cut the piping where it goes into the wall from the storage tank enroute to the tankless water heater and the function of the desuperheater was not turned on. Everthing is still in place. My question is, Do I just have to reconnect the pipes to the storage tank and turn on the function to make this operational or could it be more complicated? Does anything need to be changed on the tankless?
