What’s the difference between traditional and tankless water heaters?

The main difference between traditional and tankless water heaters is the way they heat and store water. Traditional water heaters have a large tank that stores and heats a set amount of water, which is dispensed when needed. On the other hand, tankless water heaters heat water on demand as it passes through the unit, without the need for a storage tank. This can provide energy savings by only heating water as needed, rather than constantly maintaining a heated tank. However, tankless units may have higher upfront costs and may not be able to supply as much hot water simultaneously as traditional units. Additionally, installation and maintenance requirements can differ between the two types of water heaters.
