COMMONLY ASKED QUESTIONS

What does the Energy Factor (EF) on my water heater mean?
The water heater Energy Factor (EF) is a measure of the overall efficiency of the water heater. This is determined by comparing the energy in the heated water used daily to the total daily energy consumption of the water heater. The EF can be used to compare the energy efficiency of water heaters. Water heaters with higher EFs will have lower annual operating costs than comparable models with lower EFs. A higher EF signifies a more efficient the model. Water heaters with high EF ratings may cost more initially but save energy and money in the long run. Eventually, they will pay for themselves through a lifetime of energy savings.

If my basement flooded, do I need to replace my water heater?
The Gas Appliance Manufacturers Association (GAMA) has determined that any gas appliance exposed to flooding should be replaced. Potential damage to controls on oil, gas and electric water heaters present an increased risk factor to the homeowner. This damage may be visible, but can also be hidden behind a cover or jacket. Exposure to flooding conditions can cause corrosion of controls and components, a build-up of dirt/debris or a short circuit situation. Even though appliances exposed to flooding may appear to be operational, the gradual buildup of dirt and corrosion over time can render safety devices inoperative.

Why doesn't my old water heater make as much hot water as it used to?
You might have sediment buildup in your tank. As water heaters age, they tend to accumulate sediment and lime deposits. If the heaters are not cleaned periodically, the sediment may rise to a level that will act as a barrier between the burner and the water, making it harder to heat. An article published in a national ASPE plumbing journal states: for every half inch of sediment on the bottom of a gas fired water heater, it requires 70% more fuel to heat the water.

Why does my water smell like rotten eggs?
The combined presence of hydrogen, sulfur, and bacteria cause foul smelling water. The magnesium anode rod installed in the tank protects the tank surface but generates enough hydrogen to create an odor when it interacts with sulfur in the water or bacteria in the tank. Replacing the magnesium anode rod with an aluminum anode may minimize the problem. The most efficient method of eliminating the hydrogen sulfide odor is to control the bacteria. As a rule, chlorination of public water supplies kills the bacteria, but some private well systems may need to be purified by the use of chlorine injectors or ultraviolet light. This will destroy the bacteria.

Is a drain pan necessary?
A water heater should be placed in an area that will prevent damage to floors, ceilings, and furniture if the heater leaks. When this is not possible, a drain pan must be installed under the water heater. Since a typical drain pan doesn't hold that much water, it must have a pipe to a drain or other outlet for the water. When installed properly, a drain pan and pipe will keep any leakage under control and protect your belongings from water damage.

What type of maintenance should I do on my water heater?
Contact Vander Hyde to perform maintenance or repairs to your water heater – from periodic checks on the anode rod to ensuring that all connections are secure. However, there are a few things that you can do:
Ensure that there are no sources of flammable vapors in the same area as your water heater (this includes gasoline, heating oils, lighter fluid, propane, etc.)
Keep the top of the water heater clean. If you notice water dripping on the water heater from any piping, contact Vander Hyde to have the leak repaired.
Keep the space around your water heater clean and free of dirt, boxes, paint cans, aerosol cans, household cleaners and trash. It is important to keep the heater accessible for proper operation and easy maintenance.
