What is the heating element in the instantaneous water heater?

The heating element in an instantaneous water heater, also known as a tankless water heater, is typically an electric coil or a gas burner. These elements rapidly heat the water as it flows through the unit. Here’s a brief overview of both types:

Electric Tankless Water Heaters:

Heating Element: The heating element is usually made of metal, such as copper or stainless steel, formed into a coil or other shape to maximize surface area for heat transfer. The electric current passes through the coil, generating heat due to electrical resistance, which then heats the water passing over or around the element.

Gas Tankless Water Heaters:

Heating Element: The heating element in gas tankless water heaters is a gas burner. When hot water is needed, the flow sensor detects water movement and ignites the gas burner. The burner heats the water as it flows through a heat exchanger, which is typically made of copper or stainless steel for efficient heat transfer.
