How a tankless works

 

A tankless water heater provides hot water on demand, unlike traditional tank water heaters that store and constantly heat a limited amount of water (e.g., 50 gallons). If you’ve ever run out of hot water while filling a bathtub, it’s because a tank heater can’t keep up with high demand. A gas tankless water heater, however, can deliver up to 12 gallons per minute (gpm) of hot water continuously—enough for multiple showers (each using 1.8–2.2 gpm) or other tasks without running out.

 

Here’s how it works, simplified: Imagine a copper pipe coiled inside a box (called a heat exchanger) with a powerful gas burner underneath. When you turn on a hot water faucet, the tankless heater senses the water flow and instantly ignites the burner. Cold water flows through the coiled pipe, gets heated by the flame, and comes out hot through your faucet. As long as the faucet is on, the heater keeps producing hot water. When you turn the faucet off, the burner shuts off, saving energy.

Unlike tank heaters, which keep water hot 24 hours - 7 days a week  (wasting energy at 120–140°F even when you’re not using it), a tankless heater only works when you need hot water. No demand, no energy used—saving you money.
