The energy factor is a number that reflects the efficiency of a water heater. It’s calculated by dividing the amount of heat produced by the water heater (measured in British Thermal Units, or BTUs) by the amount of fuel consumed by the water heater (measured in watts). The higher the energy factor, the more efficient the water heater.

Q: Is a higher or lower energy factor better?
A: There is no definitive answer to this question since it depends on the specific situation and application. In general, a higher energy factor indicates more efficiency, but there may be other factors to consider as well.
Q: What is a good energy factor for a water heater?
A: There is no definitive answer to this question as different homes and families have different energy needs. However, a good rule of thumb is to choose a water heater with an energy factor of around .75 or higher. This will ensure that your water heater is efficient and will help to keep your energy bills low.
Q: What is a good UEF number?
A: There is no definitive answer to this question, as each individual’s preferences and needs will differ. However, a good starting point for choosing a UEQ score is to consider what range of scores is most important to you in terms of the different aspects of your life that are important to you. For example, if you are primarily concerned with your academic performance, you may want to choose a score that falls within the range of 85-90. Alternatively, if you are more concerned with your overall well-being, you may want to choose a score that falls within the range of 95-100.
Q: What is the energy factor of a tankless water heater?
A: The energy factor of a tankless water heater is the amount of heat that is transferred to the water divided by the amount of energy that is used to generate that heat.
