Tankless Water Heater FAQs

Considering a tankless water heater? Get answers to frequently asked questions about tankless water heaters and connect with reputable installers in USA.

Is a tankless water heater worth it?

Tankless water heaters offer long-term energy savings, continuous hot water, and space efficiency. However, their upfront cost is higher. It is a worthwhile investment if you have high hot water demand, value energy efficiency, or need to save space.

How do tankless water heaters work?

Unlike traditional tank water heaters that store hot water, tankless water heaters, also called on-demand water heaters, only heat water when needed:
  1. Cold water enters the unit when you turn on a hot water tap.
  2. A flow sensor detects the water flow and activates the heating element (gas burner or electric coils).
  3. The heating element quickly raises the water temperature to the set point.
  4. Hot water is delivered to the fixture, providing instant and continuous hot water for as long as the tap is on.
This eliminates standby heat loss and ensures hot water availability.

What is a gas tankless water heater?

A gas tankless water heater is fueled by natural gas or propane. It heats water rapidly using a high-powered burner, eliminating the need for a storage tank. They are generally more efficient than electric tankless water heaters.

What is the warranty on a tankless water heater?

Tankless water heater warranties vary depending on the brand and model. They typically include coverage for parts, labor, and heat exchanger. It's essential to review the specific warranty terms for the unit you are considering. High-quality tankless water heaters often come with longer warranties, ranging from 5 to 15 years, providing added assurance and protection for your investment.
