Never Run Out of Hot Water Again: What Is a Tankless Water Heater?
Introduction: Why More Homeowners Are Switching to Tankless Water Heaters
Have you ever run out of hot water in the middle of a shower? Traditional water heaters store a limited amount of hot water, which means once the tank is empty, you have to wait for it to refill and reheat. This is where a tankless water heater—also known as an on-demand water heater—comes in.
A tankless water heater heats water only when needed, providing an instant and continuous supply without the need for a bulky storage tank. But should you choose an electric tankless water heater or a tankless gas water heater? In this guide, we’ll explore how these systems work, their benefits, installation costs, and which option might be best for your home.
How Does a Tankless Water Heater Work?
Unlike traditional water heaters that store and preheat gallons of water, a tankless water heater activates only when you turn on a faucet or appliance that needs hot water. The water flows through high-powered heating elements (electric or gas), instantly heating it to your desired temperature.
