Hot Water Heater FAQs and Information

Traditional hot water heaters with storage tanks usually hold about 40 gallons of water, although there are models available that hold more or less. Tank models require a recovery period after the hot water in the tank runs out. Tankless hot water heaters provide sustained periods of hot water, heating water as you demand it, and are ideal for larger households.

The water is not hot.

A few things can cause the water to be cold, and they differ depending upon the type of water heater you have: gas or electric.

For a gas or electric water heater, the first thing to do is to ensure the unit is on. Most homes will have a dedicated breaker for the water heater in the electrical panel. Check to make sure the breaker is not tripped, or in the off position.

If you’re comfortable with it, you can remove the metal cover at the bottom of the water heater to see if the unit is getting gas or propane. Then go through the following steps:

 Turn the dial on the water heater to “Pilot,” so that the system does not attempt to ignite with the cover off. If you see the pilot light, the unit is receiving gas.

 Make sure the temperature knob is set to 120 degrees.

 Go to a sink and turn the hot water on, then visually inspect the water heater to make sure the burner turns on. If the burner does not light, it’s best for you to contact R&D HVAC for service.

 If the burner lights, the problem should be resolved. You can then reinstall the bottom cover plate.

Check the temperature dial on the hot water heater. The ideal setting is 120℉. If the temperature is more than 120℉, turn the dial down to the desired temperature.

Generally, running out of hot water is due more to use, than to what the water heater can provide. If you find that your usage has increased, it may be worthwhile to consider upgrading to a larger water heater, or a tankless water heater.

Mineral build-up can cause water heater issues on a multitude of levels. If you have hard water, mineral deposits can settle at the bottom of the tank, which then reduces the overall capacity of the system. If you have well water, it is almost a necessity in most areas to have a water softener. Water softeners not only extend the life and efficiency of your water heater, but they may also enable you to use less hot water. If you believe you have hard water, contact us today, and one of our AquaTechs will conduct a free water analysis for you.

Water discoloration and smells are often due to minerals in the water. First, determine if the smell occurs running the hot water or the cold water. If the smell or discoloration occurs with cold water, you most likely have hard water, which can be resolved by adding a water filtration/softener to your home.

If the smell occurs with the hot water running, you may have a lot of sulfur in your water. The best thing to do is to try and flush your system. There is a drain valve at the bottom of the water heater that can be connected to a hose and then drained outside. Be sure to shut the cold water feed off before attempting this. If the smell persists after draining the water heater, it’s time to call a service technician. In most cases, the anode rod will need to be replaced.

Most hot water repairs involve leaking. Depending upon where the leak is coming from, it may be possible to repair it. This generally involves connections at the top of the tank. If the water heater is leaking anywhere from the actual tank, it must be replaced.

A general rule of thumb for replacing a water heater is every 8-12 years. In most cases, the tank itself is not repairable, if broken, so the only option is to replace it.

Most water heaters do not require regular maintenance. There are some types, however, such as a tankless hot water heater, that should be serviced annually.

Most hot water heaters will last 8-12 years, although there are new systems on the market that can last substantially longer.
