Homemade High Power Thermostatic Ceramic Air Heater! High Temperature DC Powered Air Heater. Output air temps are an impressive 200F/93C (consistent) with top temps reaching 210F/100C. To distribute the heat the unit has 2 built-in high-power fans (hooked to a speed controller) for precise airflow control. Due to the units' high heat capability (it's the hottest DC powered air heater I've ever made) I designed the stand with safety in mind. notice its very low 'center of gravity' and its long wide base. it cannot be tipped over without a lot of effort. also, the 'hot part' of the heating element doesn't touch any part of the wooden stand or the fans. it just hangs out in the 'open air'. Finally, i constructed the stand using full 1" dowels to make it very strong and sturdy. ⚡...about the power supply... the power supply that I'm using is a 12v 360w 30a switching power supply from amazon. surprisingly, those only cost about $15-$20 (i paid 15). this air heaters average amp draw is 17.66 amps (that includes the fans) but can reach as high as 20.1 amps. note that those power supplies are meant to typically only run up to 80% of max. so you'll need a supply of that size to run this unit. 🟢 Another option for running this unit is 12v batteries. I'd use either 1 or 2 100ah LiFePO4 batteries (or 2 to 4 100ah deep cycle batteries). that would give you approximately 5.5 to 11 hours of run time. another option is to hook the unit straight to solar panels, if you do that, I'd recommend no less than 4, 12v 100w Solar Panels (or 2, 12v 200w Solar Panels). you'll need that many panels to get the amps you need. all power options are explained more in the video. 🟡 This is a very warm heater. home furnace temps (at the vents) are usually anywhere from 120F/50C to 150F/65C. Another reference item is a hair dryer. those have output temps of about 140F/60C when they are on the high heat setting. 🚙 note: this heater would work great to heat the cabin of a vehicle, but the amp draw is too high for the 12v power socket. you would most likely have to wire it directly to the battery. random thoughts: the double-sided sticky-tape i used was just temporary. it will not hold the fans for very long. you have to superglue the fans to the wood. i used Loctite superglue. there is an old and new version of the element. i used the new version. input air was 68F(20C) at the time of the filming. the square dowels are sold at Home Depot and Lowes. they are usually sold in 36" lengths. to find the power supplies on amazon just search for 12v switching power supplies and to find the heating elements just search for 12v 200w ptc element. there are many suppliers of both. the speed controller is a RioRand 7v-70v 30a one (also on amazon). look for best price. i just did a search of those and they have other brands as low as $9. the RioRand one is $16 at the moment. i also just checked the arctic fans and they just doubled the price. was $10 now $20. watch for best price. here's a similar fan for $11. that one is 18,000 rpm. https://www.amazon.com/NNL-DBTB0428B2...
