How do I determine the size of heater I need for a room?

"The size of the heater you need for a room depends on the size of the room and the insulation of the space. A general rule of thumb is to use 60 watts per square meter of space. For example, if a room is 14 square meter, a 840-watt heater would be appropriate."

Bought it 2 years ago I've only used it 4 to 5 times so far, but it does contain kerosene. It will stop as soon as the refueling sign appears. What should I do?

Why does the red indicator on the side not move even when I turn the temperature adjustment dial?

The warning light comes on even though there is still enough kerosene in the fuel tank. Driving continues.
