Inline heaters, also known as in-line heaters or flow-through heaters, are heating elements designed to heat a fluid as it passes through them. Unlike tank heaters that heat a large volume of fluid stored in a vessel, inline heaters heat a continuous flow of liquid or gas. This makes them ideal for applications where immediate heating of a moving substance is required.

The principle of operation involves a heating element, typically a resistive coil or a ceramic element, situated within a housing or tube. As the fluid flows through the housing, it comes into contact with the hot element, transferring thermal energy. The rate of heating depends on factors such as the heater's power, the flow rate of the fluid, and the fluid's specific heat capacity.

Inline heaters are commonly used in various industrial, commercial, and domestic settings. Examples include heating water for showers and taps in on-demand water heating systems, maintaining the temperature of process fluids in manufacturing, heating air in HVAC systems, and in laboratory equipment for precise temperature control. They offer advantages such as compact size, rapid heating, energy efficiency due to heating only when needed, and precise temperature regulation. However, they may have limitations in heating very large volumes of fluid compared to tank heaters, and their effectiveness can be influenced by the flow dynamics of the fluid.
