Benefits of Tankless Water Heater Installation

Is that rusty relic of a water heater looking more than a little rough around the edges these days? Replacing it with a tankless water heater offers many advantages.

Newer, tankless water heaters – also referred to as on-demand or instant water heaters – eliminate the water storage tank. Its design features high-powered burners or heating elements that are activated when incoming water makes its way through a heat exchanger.

Heating water is the second largest energy expense in your home, following heating and cooling the house. There are a number of rebate and incentive programs available to help you step-up to a highly efficient electric tankless water heating system – just ask your local Mr. Electric® for information about the programs available in your area.

Tankless Water Heater Advantages

  • Significant Savings
    Rather than storing a large amount of water that must be kept to temperature until it’s needed, a tankless system’s on-demand operation offers significant energy savings. How much? Compared to conventional models, you could save:
    • 24-34% if you use 41 gallons or less per day.
    • 8-14% if you use about 86 gallons per day.
    • 27-50% if you install an on-demand system at each hot water outlet.
  • Reliability
    Tankless water heaters have a far greater life expectancy than the monolithic monster currently taking up space in your utility room. Tankless models can last close to 20 years – twice that of conventional water heater models – offering significant long-term savings in operational and replacement costs over the life of the system.
  • Added Square Footage
    No more bulky tank means you can re-work that old water heater space into something far more useful, such as added storage space or a new closet.

Tankless Water Heater Options

Options for tankless water heater upgrades include:

  • Sizing options
    • Point-of-Use
      Smaller, point-of-use systems fit under cabinets or in closets, providing water for up to two outlets (such as a sink and bath) right at the source. Unlike whole-house systems, lag time is a non-issue, thus water consumption is further reduced.
    • Whole-House
      Larger and more costly, these systems provide hot water to your whole home. They have a longer lag time, sometimes up to several minutes depending on your plumbing system’s design. For simultaneous, multiple uses in large households, additional point-of-use systems may still be necessary.
  • Fuel Options
    • Electric
      Electric tankless water heater models heat water using a filament. They offer lower volume outflow but are more energy efficient than gas models. Your local Mr. Electric can perform your electric tankless water heater installation.
    • Gas
      In gas models, the pilot light heats tubes and the water passes through them. To reduce gas usage, an intermittent ignition device (IID) can be purchased, eliminating the need for the constant pilot light. Our colleagues at your local Mr. Rooter® Plumbing can install your gas tankless water heater.

Consult a professional installer for a convenient, energy-efficient hot water supply and to ensure proper sizing that takes into account factors including the volume of water the system is required to heat, the temperature of water entering the system, and the desired end temperature and volume.
