How They Operate

How They Operate: Conventional Tank Water Heaters:

Conventional tank water heaters operate by storing and heating a predetermined amount of water within a large insulated tank. When a hot water faucet is turned on, cold water enters the tank through a supply line, displacing the hot water.

The heating element or gas burner then activates to heat the incoming cold water, raising its temperature to the desired level. As the water heats up, it rises to the top of the tank, where it can be accessed for various household needs such as bathing or dishwashing.

The conventional tank design relies on a thermostat to regulate and maintain a consistent temperature within the tank. Once the desired temperature is reached, the thermostat signals the heating element or burner to switch off until further heating is required.

This cyclical process ensures that hot water is readily available whenever needed. However, it also leads to standby heat loss as heat escapes through the insulated walls of the tank when no hot water is being used.

Tankless (On-Demand) Water Heaters: On-demand or tankless water heaters function quite differently from their conventional counterparts.

Instead of storing heated water in a reservoir, these units heat cold water on-demand as it passes through a network of coils or heat exchangers inside the unit. When a hot water tap is turned on, sensors detect this flow and activate powerful burners or electric elements that quickly heat up the passing cold water.

The absence of storage tanks allows these systems to provide an endless supply of hot water since they aren’t limited by capacity constraints. Unlike traditional tanks that constantly maintain stored hot water temperature regardless of usage frequency, tankless systems only activate when there’s demand for heated water.

This characteristic results in increased energy efficiency compared to conventional tanks since there’s no standby energy loss caused by maintaining stored temperatures. It’s important to note that while on-demand systems offer endless hot water capabilities and higher energy efficiency rates, they do have limitations in terms of simultaneous usage.

If multiple hot water outlets are being used simultaneously, the flow rate may exceed the system’s capacity and result in a reduced rate of heated water.
