Robert Campbell Me En 340 Section 1

As a poor college student, money is scarce. What is the price difference in heating my apartment with gas or electricity?

Basement Apartment 4 walls: 7.62m x m 4 windows: m x m 1 door: m x m Walls are cement, windows are glass, door is hardwood.

Apartment is insulated on the top and bottom, only heat transfer out the sides Using an electric resistance heater All energy turns to heat for natural gas combustion Temperature Apartment at 20°c Ground at 4°c Air at -6°c

Cement k = 0.60 W/m · K m thick Glass k = 0.8 W/m · K m thick Hardwood k = 0.16 W/m · K m thick

It would cost me $ a month to heat with electric. It would cost me $ a month to heat with gas. Therefore, I save $82.09 a month by heating my apartment with gas.
