Tankless Water Heater
Tankless water heaters heat water only when needed, not 24/7 like tank water heaters. Tank water heaters store water, heat it and re-heat it constantly. In addition, tank water heaters can only supply hot water based on the capacity of the tank. Tankless water heaters heat water as needed, reducing the energy usage and providing endless hot water. So cold showers are a thing of the past, even in large, busy households.
