How to convert any flame stove into a very effective heater for $1
Mesh strainers at the dollar store, the small, inside the big, joined with wire, will work with any stove to convert the flame into an actual heater that quickly heats rooms. Will work with any stove, methane natural gas, butane, propane, lpg etc. Works better than inverted colander, puts out an enormous amount of heat, so hot you cannot put your hand 12 inches above it.
Don’t touch hot metal with your hand until the flame is out and it has cooled down, common sense. Ventilation required for long duration use.
