Reliable Hot Water Starts With the Right Tankless System

Traditional tank water heaters store and reheat a fixed supply of water, which means they can leave you waiting during peak demand and burn energy around the clock, even when no one’s home. A tankless water heater heats water only as you use it, delivering endless hot water on demand while trimming your utility costs.

The energy efficiency is hard to beat. We install Navien tankless water heater systems with up to 96% thermal efficiency, and their compact, wall-mounted design frees up valuable floor space in your Avon home. Built to last 15 to 20 years, far longer than a typical tank, a quality tankless unit delivers long-term savings and dependable hot water for your household.

Electric vs. Gas Tankless Water Heaters

Tankless water heaters come in two main types, and the right one depends on your home’s size, fuel source, and hot water demand.

  • Electric Tankless Water Heaters: Compact and efficient, an electric tankless water heater is a great fit for smaller households or for heating water at a single point of use. They install in tight spaces and require no venting, making them a flexible choice for many Avon homes.
  • Gas Tankless Water Heaters: A gas tankless water heater typically delivers a higher flow rate, making it ideal for larger families running multiple fixtures at once. Our team handles the gas line and venting requirements so everything is set up safely.

Not sure which system is right for you? Our technicians will walk you through the options and help you choose the best tankless water heater for your household and budget.

Tankless Water Heater FAQs

How long does a tankless water heater last?

With proper maintenance, most tankless units last 15 to 20 years—significantly longer than the 8 to 12 years you’d expect from a traditional tank. Annual descaling and regular maintenance are the keys to reaching that lifespan, especially with Central Indiana’s hard water.

Do tankless water heaters need maintenance?

Yes. Hard water leaves mineral deposits that build up inside the heat exchanger over time, reducing efficiency and eventually causing damage. Routine tankless water heater maintenance, including a descaling flush, keeps your system running properly and protects your warranty. Our maintenance plan makes it easy to stay on schedule.

Why is my tankless water heater not producing hot water?

Common culprits include sediment buildup, a faulty thermostat or sensor, ignition problems, or a unit that’s undersized for your household’s demand. If you’re getting cold water or inconsistent temperatures, our experienced technicians can pinpoint the issue and recommend the right repair.

Is a tankless water heater worth it for an Avon home?

For most homeowners, yes. The higher energy efficiency lowers your energy bills over time, you get endless hot water instead of running out mid-shower, and the longer lifespan offsets the upfront cost. Financing options are also available to make the switch easier.

Can you replace my old tank water heater with a tankless system?

Yes, we can! We handle the full replacement process: removing your old water heater, making any gas, electrical, or venting adjustments, and installing your new system for a clean, hassle-free transition to reliable hot water.
