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 EF's  will have lower annual operating costs than comparable models with lower EF's. A higher EF signifies a more efficient model. Water heaters with high EF ratings may cost more initially butt save energy and money in the long run. Eventually they will pay for themselves through a lifetime of energy savings.

Where is the "dip tube" on my water heater?

The dip tube is another name for the cold water inlet. If you are facing the front of the water heater ( where the labels are ), the cold water inlet, or dip tube, is on the right hand side.

Why doesn't my hot 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 water heater it requires 70% more energy to heat the water.

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 pain must be installed under the water heater. Since a typical drain pan does not hold that much water it must have a pipe to 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?

Mister Hot Water Heater always recommends that you contact a plumbing professional to perform any maintenance or repairs to your hot water heater - from periodic checks on the anode rod to ensuring that all connections are secure.
