Water Heater Failing

Q. I have a gas-powered water heater that is probably 25+ years old. I have noticed moisture accumulating under the heater. I would like to know if this indicates the end is near, and it's due for replacement, or is this some sort of condensation due to humidity and rapid temperature changes? The heater is in the basement, and we've had a lot of rain and high humidity lately.

A. Heed the warnings of water heater failure on your horizon. The expected life of a water heater is 15-20 years with some lasting longer, as yours has. I suggest you arrange replacement of your water heater very soon before it becomes a problem.

I suggest you invest in a high efficiency water heater and strongly consider a sealed combustion, gas fired, water heater. They are much more costly than a regular water heater, but are more efficient with your monthly energy costs, and are a healthy and green investment.

The sealed combustion system means that the combustion air and exhaust gas remain safely contained in the intake-exhaust pipes. This means that the heated or cooled air inside your house never mixes with the “burning” air of the gas water heater. The sealed combustion system has many benefits for energy efficiency, carbon monoxide safety and cleaner indoor air quality.
