Описание к видео Sand Battery Radiant Air Heater (with opt. heat powered fan) DIY - low wattage element - on/off grid

experimental 'sand storage' air heating system. the sand (or sand battery) is heated using a DC powered stainless steel heating element. once heated, the sand 'stores and releases' its heat for hours. the heat powered stove fan is optional (but it helps move the heat around). just set it on the hot sand and it runs. only use a very low wattage element. (the standard and higher wattage ones can burn out if not used in water). element used is 12v 150 watts. unit can be run on 12v solar panels or 12v battery (off grid) if desired.

song in video is titled 'drop the tapes' from yt's music library.
