A kit of parts permits the adaptation of a known 205 litre steel drum into a fuel-burning space heater. A door assembly 4 has a frame fitting over an opening cut in one end wall of the drum, and a door is hinged on the frame and can be latched closed. The door has primary and secondary air entry openings which are adjustable in unison by a damper blade pivoted on the door. A flue outlet 17 is secured over a hole formed in the wrapper of the drum at the end remote from the door, and legs 16 are secured beneath the drum. For additional heat exchange, a second drum can be mounted above the first, with the flue of the first drum entering the second drum, and with a second flue outlet provided in the second drum. <IMAGE> |
