WebbLet’s think about three basic options to keep it simple: Standard, Energy Star, and Tankless. Standard Gas Tank: Most new water heaters have an Efficiency Factor (EF) of .58-.60. That means that 58-60% of the energy that is being used to heat your water is effectively converted into heat. Think of this as the baseline.

All … WebbThe efficiency of a water heating appliance is expressed in percentages. The percentage indicates how much energy is transferred to the water in the tank compared to how much is consumed. In the United Kingdom this percentage is usually expressed in gross value. The percentage can never be higher than 100%. WebbDOE’s water heater test procedure includes a method for calculating the Energy Factor (EF), a measure of efficiency. Manufacturers use EF to rate the energy efficiency of water heaters. During testing, a 24-hour trial is performed in which 6 equal draws are made for a total of 64.3 gallons. The energy does the labia swell during arousal
