If you are like most of our Greater Seattle, WA and Tacoma Metropolitan area customers, you have had your current water heater for a while and never really thought much about what to replace it with. If that water heater’s not cutting it anymore, though, it is time to do some looking around and figure out what type of replacement makes sense.
