Signs You Need To Replace Your Tankless Water Heater

UAT can help you determine when it’s time to upgrade your unit. Your water heater may need to be replaced if you notice:

  • Inconsistent water temperature: If your tankless water heater doesn’t provide hot enough water, it may be too small to meet your needs.
  • Visible damage: If your system is dented, corroded, leaking, or otherwise damaged, it’s best to replace it as soon as possible.
  • Constant repairs: If you need frequent tankless water heater repairs, it might be better to invest your money in a new unit.
  • System age: With proper care and luck, tankless water heaters can last 15 to 20 years. The older your unit is, the more likely replacement is best for a malfunctioning unit.

What To Expect for a Tankless Water Heater Installation

Tankless water heaters are easy to install. Most of the effort goes into getting the right system for your needs and double-checking the installation for efficiency, efficacy, and reliability.

When you work with United Air Temp, here’s what you can expect:

  • Sizing: We’ll determine the appropriate size and efficiency rating necessary to meet your hot water needs. Sizing takes into account your home’s square footage, your maximum hot water usage at any given time, and the temperature of water coming into your home.
  • Installation: We’ll carefully remove your old water heater and install your new one, changing fittings, gas lines, electrical wiring, and other components as necessary to make sure everything works as intended.
  • Testing: We’ll test your new water heater to ensure it’s comfortably hot and does not scald. We’ll also verify that all connections are secure so your tankless water heater is in top condition.

Once we’re done, speak with our team about scheduling tankless water heater maintenance every year. By flushing your system of sediment and inspecting for wear and tear, you can dramatically improve your system’s energy efficiency, lifespan, and reliability.

Getting a new water heater doesn’t need to be a financial burden. There’s no need to risk cutting corners, installing a subpar system, or delaying a much-needed system replacement.

Frequently Asked Questions About Tankless Water Heater Replacement

  • Improved energy efficiency
  • Longer system lifespan
  • Virtually unlimited hot water
  • Easy installation
  • Compact, wall-mounted unit

When you turn on the tap, cold water streams into the tankless water heater. As water passes through the system, it’s rapidly heated to the target temperature. The heated water then comes out of your faucet.

You size a tankless water heater by assessing your water temperature and the maximum amount of hot water you use at any one time, which is the combined flow rate of all hot water fixtures and appliances you expect to operate at the same time.
