The Thermoblock is typically found in consumer espresso machines. Flow Through Heaters consist of a tube brazed to the surface of a high-power heating element. Liquid (water) is pumped through the tube, taking it quickly across the full element surface, optimizing the energy transfer. This provides quick, precise and efficient, liquid heating.

Flow through heaters offer several advantages over thermoblock heaters, including rapid heating, consistent temperature control, higher efficiency, and a more compact design. They are particularly well-suited for applications requiring immediate and precise heating. While thermoblock heaters have their uses, flow through heaters are often the preferred choice in scenarios where efficiency and performance are paramount. When selecting a heating solution, it's essential to consider the specific requirements of your application to ensure optimal results.

Brazing Process: The water tube is brazed to the heating element, creating a strong, leak-proof joint. This process involves using a filler metal to bond the components at high temperatures, ensuring a durable connection that can withstand thermal cycling.

The FTH consists of a coiled or tubular heating element made of conductive material. The design maximizes the surface area in contact with the water, facilitating efficient heat transfer.
