Understanding Tankless Water Heaters
Tankless water heaters, also known as on-demand water heaters, heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by either gas or electric elements. This process allows for an endless supply of hot water, making them an excellent choice for homes with high water demands.
How Do They Work?
Tankless water heaters utilize either a gas burner or an electric heating element to heat water on demand. When hot water is needed, cold water flows through the unit and activates the heating element, ensuring you receive hot water almost instantly.
Benefits of 10 GPM Tankless Water Heaters
- Endless Hot Water: Never worry about running out of hot water again.
- Energy Efficiency: Only heats water when needed, reducing energy costs.
- Space-Saving Design: Compact and can be installed in smaller spaces compared to traditional water heaters.
- Longer Lifespan: Typically lasts longer than traditional tank water heaters.
- Lower Carbon Footprint: Energy-efficient models can help reduce greenhouse gas emissions.
