We also have a tankless at the house, and it runs on propane. Takes minimal propane because it only fires up when you turn on the hot water, and instantly heats. When hot water shut off, propane shuts off. My propane bill for six months at the house, for the heater, my grill, fireplace, and stove runs $200 for a once a year fill. Required some custom plumbing work and as indicated previously was expensive, three times the cost of a standard hot water heater.
