$250 · Daystar Val6 kerosene heater

53,000 BTUs This is better than a propane torpedo heater because: -Can run in shop/shed/hoarding with ventilation -Does not add humidity into atmosphere, it heats AND dries, unlike burning propane -MUCH quieter, you can hear yourself think/run it after hours without pissing neighbours off -also runs fine on diesel, but doesn’t burn quite as clean as kerosene. This unit is $1400+ new, and you can buy a knock off for $900. This heater is made in Japan.
