When building new single family homes, what percent of the time would each of the following describe your role in the decision on the type of heating system to install? (Numbers must sum to 100.) We make the entire decision based on our understanding of the market. We strongly recommend one option, and the homebuyer agrees. We provide several options, and the homebuyer chooses. The homebuyer already knows what they want and tells us what to install.

Natural gas is currently available in the area and the Federal minimum efficiency requirement for natural gas furnaces is the same as it is today. What percentage of your new home installations would be in each of the following categories? (NOTE: the total of all categories must be 100.)

13. Consider this scenario (2): You are deciding what heating and water heating systems to install in your new homes. Natural gas is currently available in the area and the Federal minimum efficiency requirement has changed to high efficiency (condensing) furnaces.
