I am interested in this question too. I have read in lots of places that 'room temperature' of around 21 degrees Celsius is fine, and that a slightly lower temperature is preferable to an artificial heat source. However the room my tarantulas are in drops to around 15 degrees regularly in winter (this will be my first winter with tarantulas), and I suspect that that is lower than 'slightly lower' lol. So I have got an oil filled radiator about half a metre away from them, so that hopefully they will benefit from the raise to room temperature without the heat being directly near them.I am not sure if I am doing right though! I also have slings and soon want to purchase an avicularia. I have heard that slings and avicularia are more susceptible to the cold? So this is another reason why I thought the heater was for the best in winter. However I do tend to lower it/turn it off at night.
