A tankless water heater is a type of water heater that doesn’t use a tank. Instead of storing hot water, tankless water heaters heat water on demand. This means that you’ll never have to worry about running out of hot water. Because tankless water heaters don’t use a tank, they’re typically smaller in size than traditional water heaters. This makes them a great choice for small homes or apartments.

• The Pros of Tankless Water Heaters
  One of the biggest advantages of tankless water heaters is that they’re very energy-efficient. Because they only heat water when you need it, rather than keeping a tank full of hot water all the time, they use less energy overall. This can lead to lower energy bills each month.

  Additionally, tankless water heaters have a longer lifespan than traditional water heaters since they don’t have to work as hard to maintain a consistent temperature.

• The Cons of Tankless Water Heaters
  Although tankless water heaters have many advantages, there are also some potential drawbacks to consider. One downside is that they may require a higher initial investment than traditional water heaters since they tend to be more expensive upfront.

Also, because tankless water heaters heat water on demand, they may not be able to keep up with high-demand situations like large families taking multiple showers in quick succession.
