gennemstrømsvandvarmer

A gennemstrømsvandvarmer, also known as an instantaneous water heater or tankless water heater, is a device that heats water on demand as it flows through the unit. Unlike traditional storage water heaters that maintain a large tank of hot water, a gennemstrømsvandvarmer uses a heating element, typically gas or electric, to rapidly heat the water as it is needed. This means there is no waiting for a tank to reheat and no energy is wasted keeping a large volume of water hot when it's not being used.

The operation of a gennemstrømsvandvarmer is activated by the flow of water. When a hot water tap is turned on, the unit detects the flow and ignites the burner (in gas models) or activates the heating element (in electric models). The water then passes over this heat source, reaching the desired temperature before exiting the unit. When the tap is turned off, the heating process stops immediately. This on-demand heating system can lead to significant energy savings compared to storage water heaters, as it avoids standby heat losses.

Gennemstrømsvandvarmere are available in various sizes and capacities to suit different household needs. They are often praised for their efficiency, compact size, and continuous supply of hot water. However, they may have limitations regarding the flow rate of hot water they can supply simultaneously to multiple outlets, and larger models may require more powerful gas lines or electrical circuits. Maintenance typically involves descaling to ensure optimal performance.
