DIY Radiant Brick Space Heater with Copper Plates! 300F/150C (12v) 220C/428F PTC (10lb thermal mass)

Описание: DIY "Copper and Brick" Thermal Mass Space Heater! Radiant Brick Space Heater with Copper Plates! made with two 5 pound 'stone bricks', two sheets of 24-gauge copper (99.9% pure) and 4 12v DC powered heating tablets. the heating tablets have an average heat output of over 300F/150C (with max rating of 428F/220C +/-10%). the elements heat up the copper plates to 300F/150C in seconds (which then quickly transfers to the bricks). the elements heat up in seconds and within 10 minutes the bricks are fully heated. for extended heat distribution a small fan can be used. a 'heat powered' fan is shown in the video. all you do is set it on the hot bricks (or hot copper) and it runs. if you like the video, please share it around with anyone and everyone! 👍🙂

Couple of final thoughts...

🟢 The DC powered heating tablets (also called PTC heating tablets) can be powered using a 12v battery or a 12v solar panel (so the unit can be run 'off grid' if desired). unit was pulling around 10 amps during testing (measured around 2.6 amps per element). average total power draw of the heater (120w)

🟢 I made a similar unit with no copper sheeting a couple of years ago. it works good too, but it takes over 2 hours to fully heat up the bricks (versus only 10-15 minutes with this newer unit). adding the 2 copper plates makes a huge difference in both how fast the bricks heat up and how hot they get. the bricks in the older unit got to 200F in about 2.5 hours but the bricks in this newer unit get to 272F/133C in only 15 minutes. *so the unit can be made without the copper (but be prepared to wait a while for the heat).
