Hot in Chinese! Rangetop

In my continuing quest to be lazy and also learn Chinese, I am posting here for help on how to say "rangetop". I'm going to replace the gas rangetop here in my apt and will need to talk to the clerk about all the various options, sizes, etc.

Actually, I decided already on the model I want, but I figure, why not make this little bit of "life" into a learning opportunity!

So how does one say, rangetop versus stove, gas versus electricity? Is the size correct, width versus length. Do you deliver, is it easy to install?

 And anyone know what I should know about buying a rangetop, there are like a kajiilion variations, glass top, metal top, etc., etc.,
