What You Should Know About Tankless Water Heaters

According to Energy Star, an international standard for energy efficiency created by the U.S. Environmental Protection Agency (EPA), water heaters are at the second spot among the highest sources of energy usage in the home. That’s why any addition in the efficiency of a water heating system can be a good source of savings. So how do tankless water heaters play into this?

What You Should Know About Tankless Water Heaters

Tankless Water Heaters

Would it be a good decision to have a plumbing company install a tankless water heater into your home? First, here’s how they work:

The Department of Energy indicates that this kind of water heater delivers hot water on demand (thus, its other name: demand-type or instantaneous water heater). It does so by heating water directly without the use of a storage tank. When the user turns on the hot water tap, the cold water will run through the pipe and into the heating unit to be heated by an electric element or gas burner. Thus, the water comes out hot.

Energy Savings

One of the best reasons for you to have a tankless water heater installed in your home is its efficiency. For a household that uses less than or equal to 41 gallons a day, tankless heaters can offer 24 to 34 percent better energy efficiency compared to conventional storage tank type heaters. For those that use about 86 gallons a day however, energy efficiency can be amped up to 8 to 14 percent. If a demand-type heater is installed for each outlet, the efficiency can go up by 27 to 50 percent. The estimated savings for an average household is $100 or greater annually.

It’s not just savings in energy bills that a higher efficiency creates. There’s also a bigger picture to it. By running systems with improved efficiency, you help the environment by reducing your carbon footprint.

Other Advantages

Tankless heaters also have superior longevity: 20 years compared to 10 to 15 years of conventional heaters. Moreover, this lifespan can be extended for years because of the easily replaceable parts.

With tankless systems, you won’t have to wait long for hot water. In storage tank types, you will have to wait for the tank to fill up before you can use some hot water. Tankless systems deliver hot water constantly.

If you’re interested on installing or learning more about tankless water heaters, you can consult professional Knoxville plumbers, such as The Plumbing Authority, for more information. You can also ask about other additions or services that can improve the functions of your home’s plumbing system.
