Advantages of a sealed combustion furnace in a house were presented in the book and in lecture. Two of these are 1) better efficiency, and 2) much less chance of back-drafting. Explain how the sealed combustion furnace provides these advantages. (5 points) What were the old (atmospherically-vented) energy efficiency percentages and what are the new energy efficiency percentages of sealed combustion furnaces. (2 points) Explain how back-drafting works and give 3 examples of what can cause it to happen. (5 points)
