Electric Water Heaters

Electric water heaters can be cheaper to run than gas tanks, however they don’t produce as much hot water as gas powered tanks can.

When comparing electric hot water heaters, look for the following features:

Comparison Definition In Electric Powered Tanks…
Efficiency Rating The percentage of heat transfer from the energy source to your water 88-95%(Water is heated through heating elements placed inside the tank )
Recovery Rate The amount of hot water the tank can produce in 1 hour (with 90°F increase in water temperature) 20-22 gallons/hr
First Hour Rating The amount of hot water the tank can produce in 1 hour of continuous usage 50 gallon tank, ranges 70-80 gallons
Estimated Operating Costs Cost to run the water heater per year (@ $0.086 kilowatt/hr)About $400/yr

Safety Codes for Electric Water Heaters:

  • » Bottom Board: If your electric tank is in an unheated space, such as a basement, they must be installed on an insulated surface with a minimal thermal resistance of R-10. This can increase energy efficiency by preventing heat loss from the bottom of the tank.

 

  • » Seismic Restraints: Some municipalities require that we install seismic restraints or “earthquake straps” on your hot water tank. These straps secure your hot water tank to the wall so that in the event of an earthquake your water heater will not move around and cause any damage to its surroundings.
