There are a lot of kinds of pipe that should not be used for steam heat. If you are using steam having a pipe burst can burn or even kill people in the house. It's not something to treat lightly so you should be very careful and use pipe that is rated for both the temprature and pressure of your heating system.
If you don't know then please please please call a professional. Take it from someone who has suffered through 3rd degree burns. It is so not worth a burn debridement.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
