I heat my water for washing with natural gas. I have both a tank type water heater and a tankless water heater. They both sit in the basement under my living room. I can easily switch to either using one of them or both of them to heat my water. During the summer the tankless is sufficient for my needs but not in the winter when the incoming water is very cold. Does it pay to completely drain the tank heater during the warmer months of the year when I will not use it or will it corrode more than with water in it? Richard
