I'm sure there's been studies comparing tank vs tankless operating expense - this played no factor in our choosing tankless. We needed to claim the space the traditional tank heater used in our small utility room.That's positive news.
What would be the typical fuel savings with a gas tankless compared to a traditional gas with storage and do you use a generator to power up the tankless during outages?
We have a whole house diesel standby generator and a 500 gallon propane tank for the clothes dryer, stove/oven, small fireplace and the tankless water heater. We're completely self sufficient for two or three months .
