Tankless water heaters are an excellent choice for many homes. They provide hot water on demand without the need for a large storage tank. But with different types available, how do you choose the right one? In this article, we’ll explore the different types of tankless water heaters, their benefits, and help you determine the best choice for your needs.

What is a Tankless Water Heater?

A tankless water heater, also known as an on-demand water heater, heats water only when you need it. Unlike traditional water heaters that store hot water in a tank, these units heat water directly as it flows through the system. This method eliminates the need for a storage tank, providing continuous hot water while saving space and energy. Tankless water heaters are available in electric and gas models, making them suitable for various household needs and preferences. They offer an efficient and modern solution for ensuring you always have hot water when you need it.

Electric Tankless Water Heaters

How They Work

Electric tankless water heaters use electric elements to heat water as it passes through the unit. When you turn on a hot water tap, cold water flows through the unit and is heated by the elements to the desired temperature before exiting the faucet.

Benefits of Electric Tankless Water Heaters

Electric units are generally smaller and easier to install than gas models. They do not require venting, making them suitable for homes where venting options are limited. Additionally, they are often more energy-efficient since they only heat water when needed.

Ideal Situations for Electric Units

Electric tankless water heaters are ideal for smaller households or point-of-use applications, such as in bathrooms or kitchens. They are also perfect for homes that do not have access to natural gas.

Gas Tankless Water Heaters

How They Work

Gas tankless water heaters use a burner to heat water as it flows through the unit. When a hot water tap is turned on, cold water enters the unit and is heated by the burner before being delivered to the tap.

Benefits of Gas Tankless Water Heaters

Gas units typically provide a higher flow rate compared to electric models, which means they can supply hot water to multiple outlets simultaneously. They are suitable for larger households where the demand for hot water is higher.

Ideal Situations for Gas Units

Gas tankless water heaters are perfect for homes with existing gas lines and sufficient venting options. They are also well-suited for larger families or homes with high hot water demand.

Condensing Tankless Water Heaters

How They Work

Condensing tankless water heaters use a secondary heat exchanger to capture and reuse exhaust gases. This process makes them more energy-efficient than non-condensing models.

Benefits of Condensing Units

These units are highly efficient and can save homeowners money on energy bills. They are able to provide a continuous supply of hot water, even in high-demand situations.

Ideal Situations for Condensing Units

Condensing tankless water heaters are ideal for eco-conscious homeowners looking to reduce their carbon footprint. They are suitable for both small and large households with varying hot water needs.

Non-Condensing Tankless Water Heaters

How They Work

Non-condensing tankless water heaters heat water using a single heat exchanger and vent the exhaust gases directly outside the home.

Benefits of Non-Condensing Units

Non-condensing units are typically less expensive upfront and simpler to install compared to condensing models. They still provide on-demand hot water efficiently.

Ideal Situations for Non-Condensing Units

These units are ideal for budget-conscious homeowners or those needing a straightforward installation process. They are suitable for both small and large households.

Point-of-Use Tankless Water Heaters

How They Work

Point-of-use tankless water heaters are small units installed near specific fixtures, such as a sink or shower. They heat water directly at the source, providing immediate hot water without long wait times.

Benefits of Point-of-Use Units

These units eliminate the need for long plumbing runs, reducing water waste and energy costs. They are compact and easy to install in tight spaces.

Ideal Situations for Point-of-Use Units

Point-of-use tankless water heaters are great for specific applications, such as in a bathroom or kitchen. They are perfect for homes with limited space or for boosting hot water availability in distant parts of the house.
