Over-the-Side Heaters

We have over 500 standard over-the-side immersion heaters available for online purchase. For any heater, you can choose your operating voltage, junction box, and other options before checkout.

To find the heater you need, just choose a category below; you'll be able to select a style on the next page, and then choose an individual heater.

Lead time: Most metal immersion heaters ship in 5 to 7 business days; PTFE heaters normally take 7 to 12 business days. If you need a faster lead time, please contact us, and we will find out whether it's currently possible to expedite manufacturing.

If you don't see a heater with the configuration you need, you can specify your own custom heater online with our immersion heater configurator, and get a quote for it within one business day.

If you'd like to learn more before choosing a heater, please check out "Immersion Heater Info and Tools" just above, where you'll find our article on specifying immersion heaters from start to finish, as well as our tools for finding the right sheath material, power density, and wattage. You can also request a quote with the configurator even if you don't know every detail.

If you need any assistance, feel free to send us an e-mail, fill out one of our contact forms, or give us a call at (866) 685-4443, and we'll figure it out.
