Tankless Water Heater Flush
Tankless water heaters, also known as on-demand water heaters, offer a constant supply of hot water, making them a favorite among homeowners. Unlike traditional water heaters that store and heat a large volume of water, tankless water heaters heat water as it flows through the unit. This not only saves energy but also frees up valuable space in your home.
What is a Tankless Water Heater?
Before delving into the importance of tankless water heater flushing, it’s essential to understand how these units work. A tankless water heater heats water using either electric or gas elements. When you turn on a hot water tap, cold water enters the unit, and a heating element warms it up almost instantaneously. This process ensures you have a continuous supply of hot water whenever you need it. Also read about: Tankless Water Heater Flush Kit
