Window Fan Door Open Or Closed

Window open back of the fan facing towards the window.

Window fan door open or closed.

Even if the door is closed all the solid surfaces of the bathroom are losing heat out the window and then will draw heat from the rest of the house to come back up to ambient temperature once the door is open again. What happens when you have a fan on with windows open it sucks more outside air into your house. It will draw the cooler air in. Some believe it causes hypothermia by blowing cold air on a sleeping person while others suggest that with doors and windows closed the fan merely circulates stale air causing the person to.

A fan is definitely a lot cheaper. 99 9 of everything i say is strictly for my own entertainment. Fan on inside to circulate and exhaust fan on in the bathroom to remove the hot air out. It s best if you have.

First you are losing more heat with the window open than you would by simply running the fan. When your fan is facing out the window it blows hot air out of the room which his replaced by cold air from outside.
