DERNORD Cartridge Heater 12V 100W Electric Hot Rod Stainless Steel Heating Element Replacement(Tube Diameter:8mm)

This is a very durable and reliable product that I would not hesitate to recommend to anyone.

quick shipment, durable and dependable when used

Boils water with 12 volts but make sure you have the amps to get the 100 watts. Gets hot right up to the wires so tricky to mount and seal.

I have some Star of Bethlehem flowers that are difficult to get rid of. I dug out most of them, but some tiny bulbs remain and they spread again. I am inserting this into the ground, attached to a variac (voltage controller) to cook the root bulbs, killing them in place as opposed to digging. Make sure to add water to steam kill the bulbs.

I have tried a number of these rod heaters and when they work it's convenient and great for instant heat of liquids. They must remain emersed in liquid when powered. However. I have found even so, most have a short service life. I hope this one well be better.

I used this in building a hot-pipe wood bender. (Search YouTube for a description.) This only takes about a minute to get the pipe to bending temperature, which is much faster than the pricy name-brand bender. It wouldn't hurt to have a bit more wattage but again, it's better than the expensive name-brand version.

We're using these to heat a small bath of water. After one day of continuous use, the resistance across the element went out and the element no longer heats.

Used to repair a dorm-style fridge in a camper van. OEM element was 90W and bigger in diameter. Factory hose clamp mounting made it easy to attach and wiring in the camper was more than adequate to handle the increased 11% power demand. The toughest part in repairing this broken DC element was removing the metal shielding. Once removed, repair was simple and quick. And the replacement shielding went well if you install the shield first and then stuff the fiberglass between it and the element. Two pieces of insulation - one for the back and one for the front - works easiest. Cools down the fridge on DC much faster than the previous element ever did so I suspect the OEM element was bad from the start. No way to know if there was a problem from day one until you get something that works right. If you choose to put a larger wattage element into your rig as I did, it will increase both the heat-exchange and power-demand to your system. Much like putting a larger fuse into a slot, this is not advised UNLESS the in-place wiring is capable of handling the increased demands. On the convection side, usually this will not be an issue but while you have the unit apart, clean everything with a vacuum cleaner to assure proper ventilation and air flow. You may find spiders, twigs, and maybe even a bee hive or bird nest inside so just clean everything out and you should be good.

I use it as a block heater for my generator. Works great. There is no thermostat, i control it myself

very good price and fast delivery

A brûlé dans quelques minutes et retour si compliqué que j'ai perdu mes $$$

Works as intended.
