What is a Tankless Water Heater?

A tankless water heater is a type of water heater that heats water without the use of a storage tank. Tankless water heaters can be located either inside or outside the home, and are available in both electric and gas models. While traditional water heaters store hot water in a tank, tankless units heat water on-demand, meaning they only start heating when there is a demand for hot water. Typically, these units are small and wall-mounted, which helps to save space.

Many people choose tankless water heaters for their efficiency; since there is no need to maintain a storage tank of hot water, you can save energy (and money) by only heating the water you need on demand.

Additionally, water heaters come in two main types: electric and gas. Gas models are most common in the United States, while electric models are more popular in Europe. Both work by heating water as it passes through a series of coils or elements. Gas-fired models use a burner to heat the water, while electric models use resistance coils.

There are many benefits to owning a tankless water heater.

Perhaps the most obvious benefit is that you’ll never run out of hot water. Tankless water heaters heat water on demand, so as long as you have a supply of cold water, you’ll always have access to hot water. This is in contrast to a traditional tank water heater, which can run out of hot water if you use it too frequently.

Another significant benefit is that tankless water heaters are much more energy-efficient than traditional tank heaters. Because they only heat water when you need it, there’s no heating and reheating costs associated with maintaining a large tank of hot water. This can lead to considerable savings on your energy bill.
