PTC Fan Heater 110V 200W Electric Ceramic Energy Saving Constant Temperature Thermistor Insulation Air Auto Car Fast Heating Element Tools with Power Cord, PTCYIDU

My shop where my 3d printer is located is unheated unless I'm working. This with a pid controller has helped maintain a constant chamber temperature and allowed it to continue printing in ~20 degf temperatures. No complaints.

I bought this heater for a 3D Printer enclosure and it really puts out some heat. Does the job very well for the size.

This small PTC heater does warm up quickly and works for tiny enclosed spaces, but the overall value is limited. At only two hundred watts it cannot handle anything larger than a very small compartment, and there are similar products available for less. It performs as described, but the cost does not match the output.

So far so good, I needed a small heater to control the temperature in a 3sq ft control box outside and it is performing well in 15-30 degree outside temps and has no problem maintaining 45degrees on a thermostat.

Simple but works. Works well in heated chamber for 3D printer. I have both 200 and 400watt available. In a cardboard box with a Lulzbot taz 6 the 200w will get the chamber to about 60-65ish degrees C. I have seen the 400w one push chamber temp to 76.5 C. I have a thermocouple placed 2-3 inches from the side of the print head (opposite side of heater) to monitor the temp. These temps are individually done and I don't run both at same time. Probably get over 85C then and start makes the 3D printer parts start sagging.

I used it to heat up an oven to 95 degrees F to proof bread. I had it plugged into an inkbird and it did the job.

There is definitely a wow factor on these little heaters. They are small enough to keep my projectors nice and warm while being very quiet. I have a thermostat installed to turn on at freezing temperatures and off at 50F. At 200W the amount of heat that comes off of these little things are worth the cost and you can tell the quality of it is designed to last. We have freezing temperatures here and I love the sense of security to keep my projectors in a warm and dry location.

I got the 200w version of this heater for my 3d printer, expecting it to be 42mm deep, as the listing shows. It is >50mm deep, and it didn't fit for my needs at all. It did seem to heat just fine, but that's the main positive thing I have to say about this PTC heater.
