Tankless Water Heater Installation in Avon IN

High-efficiency tankless water heater installation by professional plumbers at Cornwell Plumbing for reliable hot water solutions.Is there anything worse than being the last one in the shower and getting hit with a blast of ice-cold water? If you have a growing family or a busy household in Avon, fighting over hot water is a morning ritual you are likely tired of. You shouldn’t have to schedule your showers around your washing machine.

At Cornwell Plumbing, we believe your home should work for you, not against you. Upgrading to a tankless water heater is one of the most effective ways to eliminate those cold-water surprises and bring modern efficiency to your daily routine.

The Cornwell Plumbing Difference

For over 30 years, our family-owned business has served Avon and Hendricks County with honesty and integrity. We don’t just swap out pipes; we provide plumbing solutions that fit your life. Whether you are looking to save space, reduce energy bills, or simply enjoy endless hot water, our team is ready to guide you through the process of tankless water heater installation.

Why Avon Homeowners Are Switching to Tankless Systems

Traditional tank water heaters heat 40 to 50 gallons of water and keep it hot 24/7, regardless of whether you are home or asleep. This standby energy loss is like leaving your car idling in the driveway just in case you need to drive somewhere.

An on-demand water heater operates differently. It heats water only when you turn on the tap. Cold water travels through a pipe into the unit, where a gas burner or electric element heats it instantly.

Key Benefits of Going Tankless:

  • Endless Hot Water: You can fill a soaking tub while someone else showers, and the water will stay hot the entire time.
  • Energy Efficiency: According to the Department of Energy, homes that use 41 gallons or less of daily hot water can be 24%–34% more energy-efficient with a tankless system.
  • Space Savings: These compact units mount on the wall, freeing up valuable floor space in your garage, basement, or utility closet.
  • Longevity: Traditional tanks last 10–15 years, while well-maintained tankless units can last 20+ years.

Do Tankless Water Heaters Work Well in Indiana Winters?

This is one of the most common questions we hear. Indiana winters can be brutal, and the groundwater temperature in Avon can drop significantly during the colder months.

The short answer is: Yes, they work excellently, provided they are sized correctly.

In the summer, the water coming into your home might be 60°F, so the heater only needs to raise it to 120°F (a 60-degree rise). In January, that incoming groundwater might be closer to 45°F, requiring a 75-degree rise.

If you install an undersized unit, it may struggle to keep up with that temperature demand, leading to lukewarm water. This is why professional tankless water heater installation is critical. We calculate the necessary "temperature rise" for our specific climate zone to ensure your unit delivers steaming hot water even when there is snow on the ground.

Choosing the Right System: Gas vs. Electric

When considering a water heater replacement, the fuel source is a major factor.

Gas Tankless Heaters

For most homes in Avon, natural gas is the preferred option. Gas units generally have a higher flow rate (Gallons Per Minute or GPM) and can heat water faster than electric models. If you have a large family or multiple bathrooms, a gas-fired unit is typically the superior choice for maintaining consistent pressure and temperature.

Electric Tankless Heaters

Electric units are quieter and don't require venting, making them easier to install in some locations. However, they often require a significant amount of electrical power (sometimes requiring an upgrade to your electrical panel) and may struggle to keep up with high demand in cold climates like ours unless you invest in a heavy-duty model.

Sizing Your Unit for a 3-Bathroom House

One size does not fit all. To get the performance you expect, we look at your "peak demand"—the moment in the day when you use the most hot water.

The Installation Process: What to Expect

Installing a tankless unit is more complex than swapping out a standard tank. It involves plumbing, electrical, and often gas line work. Here is how Cornwell Plumbing handles the job:

  1. Site Assessment: We inspect your current setup, gas line size, and venting capabilities.
  2. Removal: We drain and remove your old tank, disposing of it responsibly.
  3. Mounting: We secure the new unit to the wall, ensuring proper clearance for safety.
  4. Connections: We upgrade gas lines if necessary and connect water and electrical lines.
  5. Venting: Proper venting is crucial for gas units to prevent carbon monoxide buildup. We install sealed combustion venting that meets local Avon building codes.
  6. Testing: We fire up the system, check for leaks, and set the temperature to your preference (usually 120°F).

Permits and Regulations in Avon, IN

Do I need a permit to install a tankless water heater in Avon, IN?

Yes, in most cases, replacing a water heater involves gas, electrical, and plumbing work, which requires a permit from the Town of Avon or Hendricks County building department to ensure the work meets safety codes.

Does this mean you have to spend your day standing in line at the municipal center? Not when you hire us. Cornwell Plumbing handles the permitting process for you. We ensure all work is compliant with local codes, safe for your family, and ready for inspection. We refuse to cut corners because your safety is our priority.

Cornwell plumbing was punctual, very respectful of my home and very thorough with my issue. Problem was corrected and they offered a long term solution that would take care of future issues from builder grade plumbing parts that were used. I had already looked into this option before it was offered by them. I was pleased that they offered and agreed. They came by and replace all the builder grade parts at a very reasonable price.
