If you are considering replacing your old, inefficient storage tank water heater this fall, first of all—good for you! No reason to keep a power-draining and unreliable old water heater around longer than necessary. Second of all, we recommend giving serious consideration to replacing it with a tankless water heater. You’ve probably heard about some of the great advantages of going with a tankless system: they cost much less to run, have lengthy service lives, take up little space, require fewer repairs, and best of all they won’t run out of hot water!
But we’d like to address that last benefit—because this is one of the big pluses of a tankless water heater system that will completely vanish if you don’t have the water heater installed professionally. Unless an expert plumber correctly sizes the water heater to match the demands of your household, you’ll end up with a tankless system that won’t be able to keep up.
