High-Performance BTH Immersion Heaters

BTH (Brass Tube Heater) type immersion heaters are heavy-duty, high-efficiency commercial thermal elements engineered for the rapid, direct heating of large volumes of water and mild industrial liquids. Constructed with premium heating tubes securely brazed to a robust forged brass threaded plug, these heaters are designed to be screwed directly into the side of a tank or vessel. Because the heating element makes direct physical contact with the fluid, they deliver near-100% energy transfer, making them the industry standard for commercial boilers, massive storage tanks, and heavy-duty industrial water systems.
