Ask Frost King: What Size Heat Cable Kit Should I Buy?

How do I know what size heat cable kit to buy for my house?
Well, before you go to the store first measure and see how much exposed pipe you have, once you realize how much you have, then decide how much you want to buy.
They come in increments of three, six, nine, twelve, and upwards in terms of feet, and you can get as much as you need.
