Bristol's Six Principles for Good Solar Hydronic Design Case Study - A solar combisystem home retrofit

摘要

In June of 2009, we began designing a solar heating retrofit for an existing residence in the mountain foothills outside Albuquerque, New Mexico. This house - seen on page 24 - has approximately 5,000 square feet of heated living space, and the entire building is heated with existing hydronic radiant concrete floors. The only heating fuel available is propane. The original conventional "hot water boiler" proved to have a voracious appetite. The owners wanted to cut back on propane consumption and to get better control over the energy efficiency of their home.
