Bottom-Mounted Immersion Heaters
Bottom-Mounted Immersion Heaters Overview
ZIRCO is proud to distribute INDEECO bottom-mounted immersion heaters as the official representative for Western Canada. These compact heaters feature a low-profile design that makes them ideal for applications where space is limited and short element lengths are required.
Originally developed for coffee urns, these versatile heaters have found widespread use in commercial food service equipment, healthcare sterilization systems, and industrial humidification applications throughout Alberta and across Western Canada.
Built by INDEECO with over 90 years of American manufacturing experience, these heaters deliver reliable, efficient performance with the added assurance of UL listing for safety compliance.
Why Choose INDEECO Bottom-Mounted Immersion Heaters?
Compact Low-Profile Design
Originally designed for coffee urns, the space-saving construction makes these heaters perfect for applications with limited vertical clearance where traditional immersion heaters won't fit.
Premium Tubular Elements
Made with either two or three copper-sheathed tubular elements that are silver soldered to a threaded brass fitting for superior thermal conductivity and long-lasting durability.
UL Listed Certification
All standard bottom-mounted immersion heaters, with or without low water cut-off, are UL listed for safety and compliance with Canadian electrical standards.
Easy Installation
The fitting installs through a standard 2-7/16" diameter hole in the bottom of the vessel and is secured with a brass hex nut for straightforward maintenance and replacement.
NEMA 1 Terminal Box
A NEMA 1 terminal box comes standard on all units, providing safe and reliable electrical connections for indoor general-purpose applications.
Optional Allen Head Fitting
For installation convenience, an Allen head fitting can be furnished on a NEMA 1 outlet box, allowing installation with a 3/8" Allen wrench instead of a large hex nut wrench.

Design & Installation Considerations
Bottom-mounted immersion heaters are specifically engineered for applications where vertical clearance is limited. The compact design allows installation through the bottom of vessels using a standard 2-7/16" diameter opening, making them ideal for retrofit installations and new equipment designs.
The copper-sheathed tubular elements provide excellent thermal conductivity and are suitable for heating water and other compatible fluids. The silver-soldered connection to the brass fitting ensures a secure, electrically sound bond that withstands repeated thermal cycling.
ZIRCO provides expert application support for Western Canada industries, helping you select the right bottom-mounted immersion heater configuration for your specific requirements, including wattage, voltage, and optional features.
What Is a Bottom-Mounted Immersion Heater?
A bottom-mounted immersion heater is a compact heating element assembly designed to install through the bottom of a vessel or tank. Unlike screw-in or over-the-side immersion heaters, bottom-mounted units provide a low-profile heating solution that minimizes the vertical space required inside the vessel.
These heaters are particularly valuable in applications where the heated fluid level is relatively low or where the vessel design prohibits top-entry elements. The bottom-mounting position promotes natural convection circulation as heated fluid rises, improving thermal uniformity throughout the tank.
INDEECO bottom-mounted immersion heaters leverage decades of experience in industrial electric heating, providing a reliable, maintenance-friendly solution for commercial and industrial applications across Western Canada.
