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.

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 are the best tankless water heaters?

The best tankless water heater for you depends on:
  • Your specific needs (household size, hot water usage, climate)
  • Budget
  • Energy efficiency goals
Compare models from reputable brands for the best match.

What is a recirculating pump?

A recirculation pump helps maintain hot water in your pipes. It continuously circulates water, so when you turn on a hot water tap, hot water arrives instantly, eliminating wasted water and waiting time.

How to install a tankless water heater?

Installing a tankless water heater is a complex plumbing project that requires expertise and adherence to local building codes. It's best to hire a qualified and licensed tankless water heater installer to ensure proper installation and safety. DIY installation is generally not recommended, as improper installation can lead to safety hazards, inefficient operation, and potential damage to your plumbing system.
