furnished vs. unfurnished.

[dbrooks69]

Can anyone please answer a question for me? Does it cost more/less to heat and cool a furnished vs. an unfurnished room?

[m-cooling]

My guess is the same.
What you think?

are they both sans humans?

yes.

"Things" in a room take time to heat up and cool down. The overall cost of heating (or cooling) a room has to do with heat loss in and out of the room. The things in the room build up capacitance but they don't effect heat loss.

Of course if you're talking about "finished" vs "unfinished" and not "furnished" vs. "unfurnished" as you stated, then yes, it does make a difference. A big difference.

[dbrooks69]

yes. no humans or other life forms.

I am referring to a finished carpeted furnished room vs. a room that is finished and carpeted, but otherwise empty. Are the fuel/energy costs the same or not. If they are different, why would this occur and what would be the principle behind this?

[dbrooks69]

This has been a topic of discussion around here for a few days. We are moving and have been looking at a lot of empty houses...

[jmac00]

are we talking about forced air, or radiant heat?

[dbrooks69]

forced air

[jmac00]

so lets think about this for a minute.

Lets take the empty, carpeted room....

we have a fixed volume of air? Lets assume the door is CLOSED. we have a fixed amount of air coming in and a fixed amount returning to the machine (this assumes the supply and return is sized correctly FOR THIS ROOM)

What would affect the cost of heating THAT room?

The only thing would be perimeter walls and insulation?

Lets take the exact same room and put furniture in it.

we still have the same supply and returns, but what happens if the Home owner puts a piece of furniture in front of, or on top of the supply. Or the HO's puts a rug over the return (or a picture-if on a side wall)

Now you have effected air flow and now it would cost more to heat or cool that room.

However if all things remain the same and the furniture does not block air flow, the cost would remain the same.



make sense? :anyone:

Depends on the ammount of sunlight hitting your furniture, the angle it hits and the colour of your furniture.

How many mirrors do you have? do you like warm colours? Just kidding!

that would come under the heading of BDSM.....and my SS uniform is quite toasty thank you :LOL::LOL::D:D

Here is a post by teddy bear where he tracked the inside and outside temp and humidity. It shows thermal storage in action the "flywheel effect". Yes, It costs to cool (remove the heat from) the couch, but the couch helps keep the temp even by releasing or absorbing heat.

makes sense to me.

I would think that if objects take up space, they lessen the actual sq. ft. of the structure, thus, lessening the cost to heat and cool.

can you explain how taking up space would effect the utility bill?

wouldn't wall surface area, windows and insulation effect the bill more than furniture
