This unique heater uses high intensity infrared heat that penetrates evenly and directly onto surfaces just like sunlight. Unlike traditional forced air heaters, the Val 6 is unaffected by wind or rain generating heat directly to the object without any air movement, thus no heat loss. Val 6’s combustion system produces no odor and no smoke while running. In fact, the Val 6 produces less than 2 parts per million of carbon monoxide making this suitable for running indoors. The Val 6 is also efficient, consuming 75% less fuel that a standard forced air “torpedo style” heater uses. Uses kerosene or diesel fuel. This is the perfect heater for jobsites, especially masons who need to keep walls and their workspaces warm.
