We need to replace the water heater in our house. I would really like to go with the tankless version. The current water heater is housed in a closet inside the house, (which I don't like and is a bad idea if it floods) and with the tankless we may be able to move it OUTSIDE. I have heard mixed things about the tankless heaters. Any feedback? I know they cost more so I want to make sure this would be the right choice.
