PTC Fan Heater 110V 200W Electric Ceramic Energy Saving Constant Temperature Thermistor Insulation Air Auto Car Heating Element Tools 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.

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.

I use this to keep my boat engine compartment warm through the Wisconsin winters. It works wonderfully.I would highly recommend

when it gets cold in my shop, it should preheat the enclosure fine. I have a remote thermostat that I can adjust the temperature.

I have this set up with a thermostat in a small 3’x 3’ greenhouse- it works very well to keep a consistent temperature- I would buy this again

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

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.

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.
