Indianapolis Tankless Water Heater Service


Tankless water heaters are energy-efficient solutions that provide a new way to deliver hot water in a home. Through on-demand style water heating, the heat exchanger produces just enough heating for water wherever it is required. Substantial energy is saved by reducing the amount of work done by the water heater.

About 14% of all the dollars you spend on energy bills each year goes toward heating and cooling costs. When you remove a traditional tank water heater, you can free up a lot of time and space for the things you love most. 14% may be reduced with proper sizing and installation of a tankless unit.

Request Mr. Plumber today for a free estimate learn more about our tankless water heater services for your Central Indiana homes.


What Exactly Are On-Demand Water Heaters?



Let’s start by understanding what traditional water heaters are. Most people have electric or gas water heaters that have a storage tank filled with water. That water is continually heated to the temperature that you have selected so that it is available whenever you need it. The problem is that it is being heated 24/7, and you are probably only using water a small fraction of that time. So you’re paying to keep water heated when you don’t need it which means you are using more energy and paying more in utility bills.

A tankless heater doesn’t have a storage tank. With the tankless water heater installation service we provide, it can heat water quickly and deliver it to you when you need it… on demand. Gas tankless water heater and electric tankless water heater options are available. You will save on your energy bills with this more efficient way of heating your water.

Benefits of Tankless Water Heater Installation

There are some definite advantages for Indianapolis homeowners with a new tankless water heater…


Tankless Water Heater Repair

While tankless hot water heaters are relatively low maintenance, sometimes system issues do arise. Your tankless unit may experience repair issues such as:

  • Flame Failure
  • Ignition Failure
  • Mineral Deposits
  • Overload the System
  • Cold Air Sandwich
  • Blockage in Air Intake or Exhaust Line

Your water heater won’t run right until repairs are made. Contact us at the first sign of trouble and have Mr. Plumber Indy provide elite service to keep your unit in top shape.

Maintenance Needs for a Tankless Water Heater

Tankless water heaters indeed require little maintenance, but make sure you don’t misinterpret that as no maintenance or you’re in for big trouble!

If you have hard water, maintenance is especially important. If mineral deposits collect in water heater lines, they restrict water flow and slow down flow rates. In this condition, the unit expends a great amount of energy and becomes quite wasteful. Continued operation in this shape damages components and lessens system service life.

The tankless water heater must be descaled regularly. This process requires a heavy vinegar solution to sit in the lines of the unit, then the solution was washed out for about 45 minutes to remove debris and the remaining solution.

Call Mr. Plumber Indy today and schedule a service appointment with our plumbing team and we will provide the highest level of care for your home’s important plumbing equipment.

Replacing a Tankless Water Heater

Expect a tankless model to last 2x that of a conventional tank unit – about 20 years. We’ll remove your existing water heater and hook up the new tankless system to your gas and water lines.

Once you reach this point it’s best to start uncovering replacement options. Ensure you’re in capable hands as you search – turn to Mr. Plumber Indy to receive straightforward expertise and honest answers to help you arrive at a wise choice for your household.
