To create a warmer home, is it better to close all the doors in all the rooms, or leave the doors open?

Answer 1

first what do you have in those rooms your going to close off?
is there heat in those room? if there is heat in those rooms what are you going to do about the heat being on in there..are you going to close the heat down..if you do you can cause the room to collect a lot of moisture in the ceilings and walls..and then the wallpaper and paint can start coming off the walls not to mention the possibility of getting mold in there....
would the rooms be open part of the day and closed off at other times of the day?
by closing the rooms off it will make the house that your in a little more warmer....that's what they used to do years ago when the heat was in only one room....and they would open the bedroom doors only at night when people would be in them....
so do your home work before you seal off any rooms..you do not want to mess up your home...
but for short periods of time....when no one is in the rooms....then you will make the other parts of the house warmer.

good luck

Ideally, if you close the doors, there is shouldn't be much difference. But in reality, generally with doors shut the ancillary rooms seem to warm up. The return air doesn't return like it should. The room with thermostat stays the temperature set on the thermostat, but the other rooms seem warmer. But the ambient temperature may not change, but the the exchange of air may be reduced, so it "feels" warmer. The room will defiantly be warmer if there is not return air, but there is supply in the room. Last fall, my wife left the windows open a bit, and we had an unexpected cold front. So it was freezing in the living room, the furnace tried to keep up, the bathroom doesn't have a return, so it was like sauna.

But it can work the other way, if the returns are oversized. Now you pulling more air out than supplied,so it may seem cooler. I haven't seen that, but it is possible. If there are dampers on the ductwork you can play with them to balance supply and return.

Answer 3

My home is on central air and heat and I have a guest bedroom that is not used very often. I closed the door, but also shut the vent to that room also. This way I am not heating a room that I don't use and there is more heat going to the rest of the house. I don't think closing the door alone will do much good.

Answer 4

if you close the doors and the heat vents on the rooms you aren't using you will have 2 inside walls that are cold, and no air circulation. then you will have mildew. I leave mine closed at night and open in the day with no problems and a little lower heat bill.

Answer 5

Leave doors open.Just close vents in those rooms you dont use.This will at least force most of your heat to the rooms you use and enought heat will get to other rooms to help in midew and water pipes in some of your walls or floor not freezing in real cold weather.

Answer 6

Close all the doors to the rooms your not useing

Answer 7

yes, its been my experience that if I close all my doors my house both heats up faster and holds the heat longer with the doors shut-- or just try it both ways and see which is better for your home

Answer 8

close the doors to the rooms you are not using.
...but, open them slightly if its to cold in the home as the cold can affect the furniture and flooring, if they're wood.
additionally, if the house remains to cold and furniture articles are to close to the walls, mildew can start.
be frugal but smart

Answer 9

It all depends on what exactly is going on in your house as far as the heating is concerned. First I'll need to know what type of heating you have. If you have central heat and air, I may be able to help you bunches. Let me know if you have central heat and A/C, and whether or not you have a heat pump, please.
