Understanding Water Heater Efficiency Ratings

How quickly can you generate hot water — and how much it will cost?

water heater service Norfolk, ma The average U.S. household uses almost one-fifth of its energy heating water. That’s not especially shocking when you consider that the average American family consumes roughly 65 gallons of hot water each day.

It only stands to reason that you’d want the most efficient water heater available to keep your hot water expenses down. Luckily, there’s a convenient rating system to measure efficiency in traditional and tankless water heaters.

What are UEF ratings?

The rating for a water heater’s energy efficiency is called uniform energy factor, or UEF. This metric tells how much energy your water heater uses to power itself and heat water. This is a relatively new rating system. It went into place in 2017 and replaced a less precise metric called High Efficiency ratings.

The higher the UEF rating for your water heater, the more efficient it is. For example, ENERGY STAR certifications for gas-fired storage water heaters require a UEF of 0.81 or 0.86, depending on the product. Tankless gas water heaters need a UEF of 0.95 for ENERGY STAR certification.

How is UEF calculated?

The U.S. Department of Energy (DOE) assigns a water heating product a category based on its intended use. Within this category, the unit’s performance in generating hot water is evaluated. If your water heater was manufactured after 2017, look for a yellow label on it that will contain information related to its efficiency evaluation. This information includes:

The label will also tell you your unit’s usage category (or BIN) and its capacity. If you look up the model number of your water heater, you can find its UEF.
