this unit fits in perfectly with my home.Domestic water is heated with wood during the cold months in MN, but I didn't like the waste of my regular propane water heater so I installed the on demand heater and really like it.I power my world with solar panels and a windmill, so this unit is perfect,and my fear that it wasn't large enough was proven wrong the first time I showered.
