Why won't my shower heat up?

Question

One of my bathrooms haven't been used in a couple of years. I decided to clean it up and use the shower, but it will only run cold water. I'm guessing that all the years of not using the shower clogged the pipes with mineral deposits. I don't really know much about water heating, but someone told me I have to run water through the pipes. How exactly do I unclog the pipes?

Answer 1

Answer 2
