Water Heater FAQ

What type of maintenance does my hot water heater need?

Manufacturers of water heaters recommend annual maintenance from a professional plumber — from periodic checks on the anode rod, to ensuring that all connections are secure.

My hot water heater doesn’t provide as much hot water as it used to, why?

Over time, hot water heaters build up sediment. It’s this sediment and lime that will become a barrier between the burner and the water itself, making it harder for the water to heat.  The more sediment, the more fuel it requires to heat the water and the less hot water it can provide in an efficient manner.

What is the average life of a water heater?

Home hot water heater life expectancy is 9-12 years, with type of unit and water quality being factors.

How long does it take to heat up a 50 gallon hot water heater tank and how long does that last?

It generally takes 1 1/2 to 2 hours to heat up a 50 gallon tank.  The average shower uses 2 gallons of water a minute and that equals approximately 17 minutes of hot shower for a 50 gallon tank before it runs out of hot water.

Are tankless water heaters, also known as “on demand” water heaters, a good alternative?

Tankless water heaters cost a more than conventional heaters but may save you in energy costs.  The size of the unit needed will affect the price, as some units only adequately supply one or two fixtures operating simultaneously so some homes might require a large unit or more than one tankless water heater.  AAA will help you determine if a tankless water heater is right for you home.
