I am doing a physics project about specific heats of metals and linear expansion, etc. My teacher assigned
us to design a home heating system with the best efficiency (both of cost and of energy), regardless of the cost or
availability of the metal used. We need to determine the best metals to use for the heater (a pressurized steam
heater), the piping leading to the radiator, and the radiator that heats the house. I was wondering if you could
give me a professional opinion as to the kind of metals to use to aid me with this project. Thank you for your time.
