How Does a Tankless Water Heater Work?

Tankless water heaters, also known as on-demand water heaters, have revolutionized the way we access hot water in our homes. Unlike traditional storage tank heaters, tankless systems provide hot water only when needed, offering both energy efficiency and convenience. RT Heating & Cooling in Red Deer services tankless and traditional water heating units. 

The Mechanics of Tankless Water Heaters 

When a hot water tap is turned on, cold water travels through a pipe into the tankless unit. A flow sensor detects this incoming water and signals the control panel to initiate the heating process. Depending on the model, either a gas burner or an electric element heats the water instantly as it passes through the heat exchanger. This process ensures a continuous supply of hot water without the need for a storage tank. Since the water is heated on demand, energy consumption is reduced, leading to potential savings on utility bills. 

It’s important to note that while tankless water heaters provide a constant flow of hot water, the rate of flow can be limited. This means that multiple simultaneous uses—such as running a shower and a dishwasher at the same time—might stretch the unit’s capacity. Proper sizing of the unit based on household needs is crucial to ensure optimal performance.  

Tankless Water Heaters Vs. Traditional Water Heaters 

One of the primary benefits of tankless water heaters is their efficiency. Traditional tank heaters maintain a reservoir of hot water, leading to standby energy losses as the water cools and needs reheating. In contrast, tankless systems eliminate these losses by heating water only when required. This on-demand approach can result in significant energy savings over time. 

Additionally, tankless units are more compact, freeing up space that would otherwise be occupied by a bulky tank. Their design also reduces the risk of leaks and water damage associated with tank failures. Moreover, with proper maintenance, tankless water heaters often have a longer operational life compared to traditional models.  

Considerations for Homeowners 

While the benefits are substantial, there are factors to consider before transitioning to a tankless system. The initial investment for a tankless water heater is typically higher than that of a traditional tank model. However, the energy savings and extended lifespan can offset this cost over time. Installation may also require modifications to existing plumbing or electrical systems, depending on the specific requirements of the unit.
