I have had tankless water heaters in Europe for years and absolutely love them. My house in FLA is being rebuilt due to a lightning strike and I am having 2 of them put in (one for one side of the house and one for the other). I have not had an electric tankless and have not heard great reviews on them either.

I don't have natural gas to my house like you but have a gas stove/fireplace/grill and water heaters on a big underground propane tank. Have you thought of doing that? It would be cheaper to operate and more efficient than an electric tankless.
