What is a tankless water heater and how does it work?

A tankless water heater heats water on demand, eliminating the need for a storage tank. When a tap opens, cold water flows through a heat exchanger and is instantly heated by gas or electricity, providing endless hot water.

Will a tankless water heater supply enough hot water for my home?

Yes, when properly sized. Professional installers calculate your home's flow rate to ensure the system meets your simultaneous hot-water needs.

How long do tankless water heaters last?

Most tankless water heaters last 20 years or longer with regular maintenance, nearly twice the lifespan of traditional water heaters.

Do tankless water heaters need regular maintenance?

Yes, annual maintenance removes mineral buildup and keeps the system efficient. Professional flushing and filter cleaning help preserve performance and warranty coverage.

What are the advantages of switching to a tankless system?

Tankless systems provide endless hot water, lower energy bills, a compact design, and eco-friendly performance. They typically last about 20 years with proper care.

Is installation more expensive than a traditional water heater?

Yes, installation may cost more due to venting and gas line updates, but energy savings and longevity offset the higher upfront cost.

Can I convert my existing tank system to tankless?

Yes, most homes can convert from tank to tankless systems. Proper installation ensures compliance with building codes and safe venting.

What’s the difference between gas, electric, and condensing tankless models?

Gas models handle high demand, electric are ideal for smaller spaces, and condensing systems reuse exhaust heat for up to 98% efficiency.

How much maintenance does a tankless system need?

Typically once per year, including flushing, filter checks, and vent inspections. Hard-water homes may require more frequent service.
