FAQs

What are the benefits of switching to a tankless water heater?
Tankless systems provide endless hot water, higher energy efficiency, longer lifespan, and lower utility costs. They also free up space since there’s no bulky tank.
How long does a tankless water heater last?
Most tankless units last 20+ years, nearly double the lifespan of a traditional tank water heater, especially with proper maintenance and descaling.
Do tankless water heaters work for larger homes?
Yes — modern tankless systems can support small and large households. For bigger homes or high-demand situations, we may recommend a higher-capacity unit or a multi-unit setup.

Tankless water heaters should be serviced once a year to remove mineral buildup and keep the system running efficiently. Homes with hard water may need more frequent flushing.
