Frequently Asked Questions

How does a tankless water heater provide endless hot water? Unlike traditional tank systems that store and continuously heat a fixed volume of water, tankless models heat cold water on demand using high-powered heating elements or gas burners as water flows through the unit.

How long do tankless water heaters typically last? With proper annual descaling and routine maintenance, tankless water heaters generally last 20 years or more, which is nearly double the lifespan of standard tank-style water heaters.

Why is annual descaling and flushing necessary for tankless water heaters? Over time, hard water leaves calcium and mineral scale deposits inside the small heat exchanger passages. Annual flushing removes this buildup to prevent system overheating, maintain fuel efficiency, and protect your warranty.

Can a tankless water heater handle running multiple showers or appliances at once? Yes, provided the unit is sized properly for your home’s peak flow rate (measured in gallons per minute or GPM). For large households with high simultaneous demand, plumbers may install higher-capacity models or run multiple units in tandem.
