The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.
