by Nishant Gujjar SEO Executive

As the name suggests, a tankless water heater helps to heat the water directly without the tank’s usage. This type of heater is quite famous these days as it takes less space than the traditional water heaters. There is a constant supply of hot water through the help of a tankless water heater. When turned on for hot water, the cold water runs through a pipe in the tankless water heater and is further heated with the help of gas, burner or an electric element. A tankless water heater can be an excellent option for big families, as they might need a lot of hot water, and installing more than one water heater may be common for them. Having a tankless water heater ensures that you will always have hot water available for showers, dishes, and laundry. A tankless water heater provides you with an ample amount of hot water whenever needed, and it also helps save a lot on your utility bills.


  • Whenever there is a need for water, and the tap for the hot water turns on, the cold water flows through the tankless water heater from the inlet pipe.
  • When the water reaches the bottom of the water heater, the flames ignite and charge two of the heat exchangers.
  • While the water passes through a stainless steel heat exchanger, the water gets preheated.
  • The water finally exits through the hot water outlet and is continuously heated throughout the process.
  • As soon as the hot water tap switches off, the flow of cold water into the tankless water heater stops.

Types Of Tankless Water Heaters

Electric Heaters

Electric tankless water heaters can be the best choice for you if you have a house that already has a wired electric water heater. An electric tankless water heater is considered to be one of the most energy-efficient water heaters today. Getting an electric tankless water heater when your house has the apt electricity supply will save you a lot on utility bills. Going for gas or any other option would cost you more. Electric tankless water heaters can boost up the energy efficiency up to 99%.

Gas Heaters

Gas tankless heaters can be the best option for big families and commercial usage. The reason for the same is because the tankless gas heaters are more efficient and powerful than the electric ones. Gas heaters can be the best option for you if your house wiring does not support water heating. Choosing an electric one in such a case will increase your utility bills. Since they are more efficient than electric ones, they are more expensive. This type of water heater comes with an additional accessory known as a condensing unit. A condensing unit uses the heat from the exhaust fumes to heat water, and thus works more efficiently than the regular tankless water heaters. 

Commercial Heaters

A heater for a commercial purpose should have a high BTU and flow rate. For industrial use, the water requirement is heavy, so the hot water system should be quick. Mostly the commercial heaters are gas-powered. 

Whole-House Water Heaters

Often people install multiple tankless water heaters so that there is a hot water supply in the entire house. But if you are someone who does not want to go for multiple heaters, you can choose whole-house water heaters. It is a single tankless water heater that delivers hot water supply in the entire house. In such water heaters, you should always pay attention to the number of water outlets it has.

Portable and RV Heaters

As the name suggests, these are the tankless heaters and are portable. This type of heater does the same work as the others.

Hybrid Water Systems

This type of water heater is comparatively more expensive than the others. Hybrid water systems are a mixture of both the traditional and the latest tankless water heaters. This type of heater moves heat from one area to another rather than generating heat.
