It depends on the power of your heat source. Divide the total heat needed by the heat source power. If you have a 1500 W heater, time = 1.45E6/1500 ~ 1000 s, but remember that the warm air will give up some of its heat to the surroundings (furniture, walls, floor, ceiling, etc), and of course heat may also be flowing out to the outside environment.
