How long does a tankless water heater last compared to a tank?

Tankless water heaters typically last 20+ years with proper maintenance, compared to 10-12 years for traditional tank units. They also have replaceable parts, so individual components can be repaired without replacing the entire unit.

Will a tankless water heater work with my existing gas line?

Many tankless units require a larger gas line than what served your old tank water heater. During our assessment, we check your gas line size, meter capacity, and venting requirements. If upgrades are needed, we handle the gas line installation as part of the project.

Can a single tankless unit supply my whole house?

Yes, a properly sized whole-house tankless unit can supply multiple fixtures simultaneously. Sizing depends on how many fixtures you run at the same time and the incoming water temperature. In Illinois winters, the incoming water is colder, so we size units with that in mind to ensure consistent hot water.

Do tankless water heaters need maintenance?

Yes. Tankless units should be descaled annually, especially in areas with hard water like the Naperville area. Mineral buildup reduces efficiency and can damage the heat exchanger. We offer maintenance plans that include flushing the system with a descaling solution.

Is a tankless water heater worth the higher upfront cost?

For most homeowners, yes. Tankless units use 24-34% less energy than conventional tank heaters, last nearly twice as long, and take up much less space. The energy savings add up over the life of the unit, and many homeowners recoup the extra cost within a few years.

Can I install an electric tankless water heater instead of gas?

Electric tankless units work well for point-of-use applications like a single bathroom or kitchen sink. For whole-house hot water in Illinois, gas tankless is generally recommended because electric whole-house units require very high amperage that most residential electrical panels can't support without significant upgrades.
