Sizing heating systems in existing homes

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

There are many tools available to size a heating system for an existing home: REScheck, Manual J, National Energy Audit Tool, and your basic heating design load spreadsheet. How do you know if the inputs are realistic, reasonable or just a guess? In this session, we will walk through several different methods and explain the pros and cons of each tool, as well as how errors and assumptions affect the size of the proposed heating system. A comparison of the results from each tool will be highlighted for an existing home to include practical parameters for inputs to ensure the contractor is proposing a reasonable size for the home.
