Best Indianapolis Tankless Water Heater Repair and Installation

Water heating is the 3rd largest energy user in the home.

On average, it accounts for about 14% of your utility bill. This is another investment that requires an informed decision. Capacity, efficiency, and cost are among the factors to consider.

Demand (tankless or instantaneous) water heaters provide hot water only when needed. So, you only pay to heat your water when you’re using it. Considering water heating is the third largest energy user in your home, a tankless water heater has some definite advantages…

  • Up to 40% more energy efficient than a traditional natural gas water heater
  • Up to 55% more efficient than an electric water heater
  • Shuts-off automatically when hot water is not needed… saving energy and saving money!
  • Compact wall-mounted unit with a life expectancy of 20 years, whereas hot water tanks usually last around 10 years.

You need to consider the efficiency and cost of the available tankless models. It is also very important to rely on a licensed Williams Comfort Air technician to install a tankless water heater.

Energy Efficiency

The energy efficiency of a storage water heater is indicated by its Energy Factor (EF). The higher the EF, the more efficient the water heater.


You may want to save money with a less expensive traditional water heater, but don’t ignore the operating cost. You may save money at the cash register but pay more to the utility company.

Installation and Maintenance

If your tankless water heater is not installed properly, it may not operate at its optimal energy efficiency, meaning you won’t get the energy savings that you should. Proper installation depends on fuel type, climate, local building code requirements, and safety issues. Therefore, it’s best to have a Williams Comfort Air technician install your demand water heater.
