hi and thank you!

The ceramic resistance is 1 kilo homs, and fan give hot air. The ceramic is heat protected, so you can use a candle at his bottom or other heat producer separate by a piece of stainless steel or aluminium sheet, to warm up the radiator, just protect it from fire if you want less electrical energy. Imagine 10 heat candle in a demi sphere ( a cheap saladier), with this module at the top. Otherwise this set up is amazing, thank you very much, i have the same components from an old 230v heater, this confirm that it run on 12 v in reality. So we have tools for this winter , greath and love from France.

Thanx for such great ideas. Keep'em coming.

Add that to an insulated suit so you can evacuate moisture.Power up exchange air and keep warm.

Awesome.

hey there and thank you.

Another great design and build! Have you taken amp draws so you can figure watt usage? I would love to try something like this for car camping and would use it on my Jackery. Anyway, greta job!

hi. yes, that was a big part of the build on this one. I was trying to make the biggest practical heater that I could (that could be run safely through a cars 12v power socket). those are rated for 15 amps so i knew it had to a little less than that. the most powerful commercially available 12v items for use in a car pull 12 to 13 amps (so safely under the 15 amp limit). this heater draws a total of 12.5 amps so it's right in there. i hooked up a watt meter and took readings over several hours. the range was from 144w to 151w. highest reading was 151 so well below the 180 max of the power socket. the other goal with this unit was to use dual heating elements spaced apart in a way that would maximize the heating of someone sitting in front of it. it's been working great. just the right amount of heat for the chilly mornings we have been having lately.

Woah do you think this would be okay in a chicken coop? Super awesome!

i have a ceramic heating element i found at the goodwill.. its marked 110v 500watt on the side... would i need a 12v 45amp power supply to run it?

if u supply 9 volt....the temp of the hot air will actually go higher because there is less airflow....and it gives it slower time to heat up more...also the sones fan noise is reduced.....less electricity sonsumed by the fan and higher hot air temperature....

If only temp would be the main factor then a single candle could heat up your house. It is the amount of hot air that matters.

This is so cool. Is it just a personal heater or how much space can it heat?

@desertsun02

hi there and thanks. yes, it's a personal space heater. great for localized heating. if the room was on the small side, it may heat it some as well. the goal with this project was to see if using 2 elements side by side would increase the overall feel of the heat. it does because the 2 heat streams combine into one in front of the heater so you don't have to huddle in front of it to get warm from side-to-side. the other goal was to be able to run it off of a standard 12v power socket.

@@desertsun02 Just for reference, a small hair dryer heats up small space like bathroom easily within a couple minutes. I think this has something to do with the high air flow which enables lots of heated air to fill the space quick. With a radiator it would take days to reach the other side of the bathroom but hair drier pushes the air so forcefully that even low conductor like air will heat the space quick. In physical sense the speed matters in heating also. Fan has tons of more air MASS flowing than thermal mass heater. And heated air mass is only thing that matters indoors. Air is the conductor in almost every heating device not including infrared heaters. But even with infrared the heat will eventually transfer into heated air in the room and escape outdoors through ventilation. So I think that PTC fan heater should be the most effecient heating method because the fan moves the bad heat conductor air faster than radiating thermal mass. Thermal mass heater is ofcourse much better for storing the heat but if the outside temperature is pushing cold into the house the termal mass heater can't rival with the cold air speed as good as ptc fan heater can. The thermal mass heater with the copper plate and fan is like a hybrid model that has good airflow and storage. I also think that using thermal mass storage lowers the ptc element energy consumption versus the direct airflow. Because the thermal mass has higher heat resistance than quickly cooling fin elements etc. And the heat resistance means also electrical current resistance because the current is the source of the heat and when there is enough heat it will slow down the current flow. So I would suggest to get a ptc fan heater or build a thermal mass heater that has a fan integrated. Even better solution is to install thermostat into the fan circuit that fan will start blowing when the other side of the room gets below required temperature. Thermal mass would store the heat but fan would distribute it fast when needed.

Do you think these elements would work for an oven application? Thank you

i measured it over a couple of hours and the range was 144 to 151. my goal was to keep it under 180 so it could be plugged into a 12v power socket of a car. technically that is their limit. in reality their limit is about 165 watts so 144 to 151 is great.

yes, good idea. the idea behind this heater was to try using 2 heating elements (spaced apart) so their air streams would combine into a larger mass of warm air in front of the heater. works great! (of the 3 heaters that i've recently made this is the one i use the most). the other idea was to make the most powerful 12v heater that could be run off of a cars 12v power socket.

@@desertsun02 there was something called sandstone i think apparently in the old days they heated these up on a wood stove and then with metal tongs brought them to the bedroom for heat. they claim this stuff is amazing fast at absorbing heat, and slow to release, i wonder if you had a average size room in a house ,maybe no windows, insulated walls,floor and ceiling, with maybe 2 of your devices and these stones in 2 corners, i wonder if you used it for 12 hours, would it be warm enough for the other 12? the 54 cents would be 27 cents, maybe try to set up a solar panel? to bring 27 cents to zero
