One of the most overlooked appliances in your home is likely your water heater. It sits, likely behind some type of door, for year after year, thanklessly heating up water while you ignore it completely. Until, of course, the moment you step into your shower, turn on the hot water . . . and nothing but cold comes out. Then the panic ensues, a plumber is hastily called, and a few hours later you have a new water heater in Portland OR.
