Dernord Cartridge Heater 12V 100W Electric Hot Rod Stainless Steel Heating Element Replacement

Works as intended.

Work perfect with a 100 watt solar panel no batteries required! This thing gets hot quick. I was shocked. Just make sure no to submere the wire so I plan on doing some type of float system so the heater will always be under water. Plan to buy more once I figure out how much water this one little heater can produce in a day!

Wanted for snowblower firest time it started on fire

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.

Worked amazing for its purpose and amazing heaters. Worth the buy.
