Frequently Asked Questions:


How does a tankless water heater work?

It heats water as it flows through the unit, delivering hot water on demand without storing a tankful of hot water.


How long does a tankless water heater last?

With proper maintenance, many units operate for 15–20+ years.


What maintenance does a tankless water heater need?

Annual descaling, filter cleaning, and basic checks on venting, gas, and condensate lines.


Can a tankless water heater run multiple showers at once?

Yes, when sized correctly by gallons per minute (GPM) for your climate and fixture count.


Do I need upgrades for gas, venting, or electrical?

Some installs require right-sizing gas lines, category-appropriate venting, and a condensate drain—evaluated during the estimate.
