What Is a Tankless Water Heater?
A tankless water heater heats up water on demand instead of storing heated water in a storage tank. Due to its short heating time, tankless water heaters are perfect for cooking areas, additional bathrooms, or any place where water needs to be used at any time. Also, because of its rapid heating and small size, our tankless water heaters are 90% smaller than a traditional water heater.
