My heater in my house does not work so I purchased two small electric heaters. I just received a power bill for $400. On the bill it says I used an average of 50 kwh per day and last year I only averaged 15 kwh per day. Could those small heaters really make that much of a difference?

Consider two buildings of different size but similar structures.

One has just a ground floor and has three rooms. It is prefabricated.

The other one is bigger, has 4 floors, and many rooms in each floor (about a dozen). It is also prefabricated.

Noone is artifically heated.

Does it make sense to say that you feel more cold in the first building than in the second?

Well... in order to fold 4 floors, I assume the second building has probably a more solid structure...
But even if it were the same materials...
Or could anything else justify why we feel more cold in the first building than in the second...

I need to know this in oder for people not to say I'm being unfair in my complaints...

Thanks in advance.
