Tankless Hot Water Heater Installation in Nashville, TN

Tankless water heaters have been gaining popularity over traditional systems – and with good reason. Installing a tankless water heater provides your home with endless hot water on demand. It also presents the opportunity to make sure you select the hot water heater that is right for your home, whether it’s a replacement or new installation.

Signs You Need a Nashville Tankless Water Heater Replacement

If you are asking yourself, “Does My Tankless Water Heater Need to Be Replaced?” you may already have your answer. However, here are some common signs that will tell you it is time to replace your water heater:

  • Banging, grinding, or knocking sounds – some noise is fine. These are not.
  • Inconsistent Water Temperature
  • Frequent Repairs
  • Low Water Pressure likely due to a blockage
  • Spike in Energy Bill

Types of Tankless Water Heaters We Install in Nashville

Hoffmann Brothers installs both gas and electric tankless water heaters. When considering your tankless water heater installation, keep in mind these specifics:

  • your fuel source
  • your maximum hot water demand
  • voltage and amperage requirements (electric)
  • proper ventilation (gas)
  • appropriate size unit for your household’s needs

A large Nashville household may want or need a tankless water heater that can handle four or more showers at a time, and we have a luxury line of tankless water heaters that can manage that demand.

Two units can be linked together with quick connect systems to accommodate the higher flow rate demand. They handle the demand thanks to a turbo flow feature (9.8 gallons/minute), a dual flame burner, a redesigned heat exchanger, and 25% thicker copper piping. They are also equipped with a sensor that controls the heat when you turn on the tap for a certain minimum flow rate.

A Hoffmann Brothers team member can help you find the tankless water heater that will fit your home’s hot water demands as well as your budget and plan the installation according to that model’s requirements. To get a free estimate, request a bid or call us at (615) 515-3015.

    FAQs About Tankless Water Heaters

    Who installs tankless water heaters?

    Licensed plumbing contractors are the standard choice for on demand water heater installation due to their expert knowledge of proper installation, best practices, and adherence to the appropriate local codes and laws.

    What Is a Tankless Water Heater Heat Exchanger?

    Since the heat exchanger is where the water is heated up by the dual-flame burners, it is also where most of the stress in a tankless water heater occurs. For this reason, the Tankless Water Heater utilizes a heat exchanger with 25% thicker copper piping. This helps to ensure the heat exchanger’s quality and durability is not compromised

    7 GPM (gallons/minute) gas tankless heater or at least an 18-kW electric tankless water heater if you live in the southern part of the USA.

    What size tankless water heater to replace a 40 gallon?

    A 3.5 GPM electric tankless water heater will work for a point of use installation.

    How long do tankless water heaters last?

    Gas tankless water heaters can last 20 years with proper maintenance, whereas electric tankless water heaters have a lifespan of about seven to 10 years.
