Water Heater Energy Labels Explained: Understanding EnergyGuide Stickers and Annual Operating Costs

Decoding Your Water Heater’s Energy Label: The Key to Smart Savings and Efficient Performance

When shopping for a new water heater, one of the most important tools at your disposal is often overlooked – the bright yellow EnergyGuide label. In order to help consumers comparison shop products, the Federal Trade Commission requires manufacturers to place EnergyGuide labels on appliances. Understanding how to read and interpret these labels can mean the difference between years of high energy bills and significant cost savings.

What Is an EnergyGuide Label?

Estimates of a home water heater’s energy efficiency and annual operating cost are shown on the yellow Energy Guide label. The label estimates a residential appliance’s yearly energy cost and how it compares to similar models. These government-regulated stickers provide standardized information that allows you to make informed comparisons between different water heater models and brands.

A residential water heater contributes to as much as 30 percent of a household’s energy cost – second only to the expense of a home’s heating and cooling system. This makes understanding energy efficiency ratings crucial for homeowners looking to manage their utility expenses.

Key Components of the EnergyGuide Label

Every EnergyGuide label contains several critical pieces of information designed to help consumers make informed decisions:

  • Product Type and Fuel Source: If you are looking to buy a water heater in the US, you will find the following information on the EnergyGuide label: Water heater type (tank or tankless)Model type and manufacturer · Fuel type (natural gas, propane gas, or electricity)
  • Storage Capacity: RATED STORAGE VOLUME – The storage volume measured and defined by the Department of Energy. Tank-type water heaters utilize storage tanks with the capacity shown in gallons. Tankless models use a maximum water flow rate expressed in gallons per minute (GPM rating).
  • Estimated Yearly Energy Cost: ESTIMATED YEARLY ENERGY COST – The estimated cost of energy required to operate the unit for one year, based on assumptions for daily hot water usage and average energy prices as defined by the US Government.
  • First Hour Rating (FHR): First Hour Rating (FHR) – The amount of hot water your water heater will supply per hour, starting with a full tank of hot water.
  • Cost Range Comparison: Cost range of similar models – The energy cost of similar appliances from low to high efficiency.

Understanding UEF Ratings

Modern water heaters use the Uniform Energy Factor (UEF) to measure efficiency. Uniform Energy Factor, or UEF, is the U.S. Department of Energy’s (DOE) industry standard for measuring water heater efficiency. DOE replaced Energy Factor (EF), the previous measure, in 2017 with the adoption of revised testing procedures and metrics to help consumers and contractors easily and precisely compare the efficiency among water heaters for a given installation scenario.

As you consider purchasing a new water heater, remember that the higher the UEF, the more efficient the product. It will save you more energy than other products with similar capabilities and result in lower operating costs.

UEF ratings are determined by assigning water heaters into one of four different categories of hot water usage and then evaluating their performance based on that usage. These categories are called bins. A water heater is assigned a UEF within its bin based upon its first hour rating.

Real-World Operating Costs by Water Heater Type

Understanding actual operating costs helps put the EnergyGuide numbers into perspective:

  • Gas Water Heaters: Gas water heaters have an energy cost of $120-$360 a year, with averages generally coming in at $200-$250 a year, according to a range of sources.
  • Electric Resistance Water Heaters: With conventional electric resistance water heaters, the annual energy cost range is $400-$600.
  • Heat Pump Water Heaters: Installing an Energy Star-certified heat pump water heater can take your annual energy cost to $104-$160. An ENERGY STAR certified electric water heater uses different technology and can save a household of four more approximately $600 per year on its electric bills, compared to a standard electric water heater, and more than $4,500 over its lifetime.
  • Tankless Water Heaters: Electric tankless water heaters cost $75-$300 a year to operate. Gas tankless water heaters cost $175-$500, according to retail and consumer sites.

Making Smart Purchasing Decisions

When you’re shopping for a new water heater, you can get a good idea of the operating cost thanks to the EnergyGuide label, the yellow sheet of paper with energy consumptions and cost estimates attached to many new appliances, water heaters included. EnergyGuides’ estimates for costs and consumption are based on national averages and might vary from your actual use.

For homeowners in rural areas like those seeking water heaters higbee, it’s especially important to work with experienced local professionals who understand regional energy costs and installation requirements. Don’t choose a water heater model based solely on its energy factor. When selecting a water heater, it’s also important to consider size and first hour rating, fuel type, and overall cost.

Professional Installation and Maintenance
