WalfrontCeramic Air Heater 110V 300W Insulated Heater, Aluminum Tube, Energy Efficient, Automatic Constant Temperature, High Heat Transfer Efficiency, Lightweight

I used this to build a incubator. Ink bird controller and this works great. Good value Good quality. Good size. Stable heat, auto shutoff works, no noise

I picked up two of these 120vac 200/300watt PTC heaters for a project. I selected the size that would be just about right to mount on an 120mm Wathai EC muffin fan. While the mounting slots on the PTC units were just a bit shorter than the screw holes on the fan, a little filing to extend the slots made them match up nicely. While the seller identifies the overall dimensions on the PTC units they don't specify the mounting hole dimensions. Hopefully the seller will add that info. That's the only negative I could identify with this purchase.I mounted both PTC heaters onto the Wathai fan with a mounting plate so the assembly could be mounted on a wall in my on-demand water heater "closet". Since the heater has to have a fresh air vent to the outside in case of gas build up I've always had a heat lamp activated by a thermal cube for the very cold nights - just in case. The high reliability rating of the Wathai fan and these PTC heaters will avoid the worry of if the heatlamp has burned out.The Wathai fan used puts out 88 cfm and with the two PTC heaters it is quickly blowing a nice 140-150F stream of air. At this constant airflow, the combined power consumption of the two heaters quickly rises to about 700 watts shortly after turn on and then gradually reduces to a steady power consumption of 550 watts. Just right for a quick warm-up of the water heater closet.Excellent little heaters and as long as you have a good airflow to keep them below their maximum operating temperature they should last a long time. Highly recommend for any small space heating project!

The design is simple and functional, I thought it was pretty good, I hope it can keep working for a long time

The media could not be loaded. recieved on time, item wrapped in bubble wrap in great condition, installed with a 3" fan and a pid for a filament drier, working good, heats up in a few minutes and better then the 150watt lightbulb i was using. I'll buy another if need to.

Mounted it to a 4" computer fan with1/4" spacers and 1 1/4" standoffs on the fan to allow it to pull air up through it.Very impressed with the amount of heat it puts out.Using it with a temp controller and its working better than I ever expected so I'm happy with it. Very nice little heater.

This item got so hot I almost burned myself trying to install this in my car

As advertised but Philips bolts connecting the black bracket to the metal heating element were completely stripped and one bracket was slightly bent

nice little heater
