PTC Fan Heater 110V 400W Electric Ceramic Heating Element Energy Saving Constant Temperature Thermistor Insulation Air Heater Fast Heating with Power Cord, PTCYIDU

Bought this for my 3D printer enclosure to help with printing engineering filaments like ASA. This works like a charm! Puts out a decent amount of heat, especially for its compact size. Great value for the money here! Air flow won't blow anyone away, but you don't really want a TON of airflow for a heater like this - just enough for circ. Looks like it's well engineered, too.

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.

Been using it for a few months now for starting seedlings and it works well when used in tandem with a temperature control probe. Heat output persists in its intensity and ability to reach high temps quickly, build quality remains intact so far.

PTC Fan Heater with Power Cord 110V 400W Electric Ceramic Heating Element Energy SavingThis is a great little product. We have integrated into our electronics containers and they have worked great. Very simple construction and priced very well. Have used for one field deployment so far and all 8 units were fine.Combined with "bayite Temperature Controller 1650W 15A BTC211 Dual Digital Outlet Thermostat Plug," also available on Amazon.

This little 110v heater is pretty impressive. Have the first one I bought on a timer for a paludarium I built. Bought a 2nd one for my new build but will be on a thermostat this round. It doesn't get overly hot itself, but puts out good hot air. It's quiet and plug-n-play. It does not have a Stat to regulate heat.... either on or off unless you have it connected to timer or external stat

I'm very satisfied with these little heaters. They work well and have good quality wiring and build quality. I have mine plugged into a thermostat that takes all the worry out of things.

This 200w model puts out a decent amount of heat for the size. I would recommend putting a thermal fuse or limit switch on it though, all fans fail at some point.

While this does work effectively there is a bit of concern about the safety of the wiring at the heater itself. After running this for 10 minutes the joint where the 3 power feeds to the ptc crimp together get extremely hot. I opened it up and put a couple wraps of Kapton tape in separating the hot and neutral joints just in case it melted. I wouldn't leave this thing running unsupervised, I believe the leads to the heater itself are undersized causing the issue. That being said the joints, heat shrink and crimps look fine otherwise. When running it definitely has a smell and the noise is tolerable. I'm using it for a filament dryer, in an uninsulated 19litre water tight box box it gets up to 150F in about 10 minutes or so. I haven't used it for the full drying time yet so my review may change.
