Tankless Water Heaters Vs Storage Tank Water Heaters

CR’s experts weigh in, based on test results and payback time

You know that big tank of hot water in your basement? What if we told you that you could get the same amount of hot water from a water heater the size of a carry-on suitcaseand save at least $100 a year on your utility bill?

Thats the promise of tankless water heaters, also called on-demand water heaters, which produce hot water only when you turn on the faucet, start a cycle on the washing machine, switch on the dishwasher, or otherwise call for hot water.

While storage tank water heaters are by far the most common type, tankless water heaters are slowly gaining market share, according to Technavio, a global market research firm. Thats because of their reputation for running more efficiently, an appealing characteristic given that heating water is the average U.S. home’s second highest utility cost after heating and cooling the house itself.

Consumer Reports recently tested four electric and five gas whole-house tankless water heaters from such brands as Bosch, Navien, Noritz, Rheem, Rinnai, Tempra, and Trutankless to see how costs, performance, and energy use stack up against that of conventional storage tank water heaters. We’ll walk you through the results and considerations of going tankless.

How To Find The Right Size Hot Water Heater

Sizing is a crucial factor that will determine your tankless water heater cost . There are two factors youll want to consider when sizing a tankless water heater:

  • Flow rate Tankless hot water heaters heat water instantaneously . The flow rate measures the maximum amount of water they can heat on demand.
  • Temperature Rise The temperature of the incoming cold water referred to as the groundwater temperature determines how much energy will be needed to heat the water. Temperature rise is measured by taking the desired hot water temperature minus the incoming ground water temperature .
  • The important thing to remember is that the higher the temperature rise needed, the lower the flow rate. Almost all models will include the GPMs based on different temperature rises in the product information like the image below.

    Notice that they list three things:

  • A map of the inlet temperature
  • The GPMs their model achieves based on different inlet temperatures
  • GPMs of commonly applications
  • Pro tip: If you really want to be precise in your required GPM estimate, turn on the water of any fixture and fill a bucket to a 1-quart mark. Dividing 15 by that number of seconds equals gpm.

    Electric Tankless Water Heater Facts

    Homes without a gas line or propane tank can also enjoy the advantages of on-demand hot water by installing tankless units powered by electricity. These units, which heat water with thick copper rods, are quieter and about a third smaller than gas or propane tankless heaters. And because they dont need vents, they can be installed almost anywhere, including under sinks and in small closets.

    One drawback to electric units is its limited output, which tops out at 36 kilowatts, or about 123,000 Btus. That may be enough to supply a whole house in areas with warm groundwater, but in colder climes theyre better suited to point-of-use service, where the demand for hot water doesnt get too high. Whichever type you choose, it will need sufficient amperage at the main panel and heavy-gauge wires.

    Also, electric heaters last only about half as long as gas units: Typical warranties are three to five years. Once the heating elements fry, it usually costs about as much to replace the entire heater as it does to swap in new elements.

    What Are The Pros And Cons Of Tankless Water Heaters

    In recent years tankless hot water heaters have become increasingly popular in America. Compared to conventional an electric water heater, they are much cheaper to operate since they only heat water when you need it. They also take up much less space in your home than the more energy efficient hybrid water heater. However, if you are switching from a conventional tank, the installation cost will be higher.



    • Higher installation cost Depending on your home, a tankless water heater may cost more to install. Thats because most homes in America have conventional electric water heaters and switching requires more labor and parts than simply replacing an old unit with the same type of heater.
    • High GPM capacity models are expensive Tankless hot water heaters are best if you dont need to use a lot of hot water simultaneously. You can buy models that offer as much as 12 GPMs , but they are expensive .
    • Longer payback period If your installation costs are high that means it will take longer for the monthly savings to pay themselves off. You can figure out exactly how long it will take by dividing the total cost by the monthly or yearly savings.

    How Much Does A Tankless Water Heater Cost

    The cost of a tankless water heater is usually between $1,000-$4,500. You will probably hear people talk about the total installed cost. Thats another way of saying the cost of the unit, labor and parts. This is a better way to look at it than simply looking at the tankless water heater price. Below well break down those costs in more detail and help you understand a tankless water heater average cost.

    For example, Fixr says that the average tankless water heater is $2,800. But keep in mind that according to the latest census, the average American home is 2,392 square feet. According to Pew Research, the average home has 2.64 people living in it. And while I dont have any data or sources to back this up, Id venture to say that the average plumber is going to recommend a water heater that covers every edge case and errs far on the side of more, rather than less capacity. .

    Why is all that important? Because every home, person, and family is different.

    As I write this, I am sitting in a 1,100 square foot home . My last apartment was 800 square feet. I live with one other person who takes showers two hours earlier than me each morning. We run the dishwasher and laundry at night . That means the GPMs we would need are going to be far lower than the average, which means the cost of a tankless water heater would be much lower.
