Hereof, how much heat does a tea light produce?

According to Wikipedia, a single tealight has an energy output of about 100 BTU/hr. A small space heater, capable of heating a small room, is 5000 BTU/hr. Thus, you actually would need fifty candles to heat the room as efficiently as a space heater, instead of just four.
