Tankless vs Standard Water Heaters
As you may have guessed, the key innovation behind tankless water heaters is the elimination of the traditional storage tank. Instead of constantly holding preheated water in reserve, tankless units can supply hot water on demand. When you turn on the tap, water passing through the system is directly heated by a gas burner or electric element. This happens almost instantly, which means no more wasting water as you wait for it to warm up. Since there’s no storage tank for preheated water, there’s also no need to worry about running out. There’s a lot to love about on-demand tankless systems, including:
- Unsurpassed convenience
- Lower monthly utility expenses
- Compact, space-saving designs
