Imagine a conscientious plumbing and heating
contractor who has installed zoned baseboard systems for years, and has always
had those systems perform as expected. Along comes a great opportunity for his
company to install a system in an 10,000-square-foot custom home where the
owner wants radiant heating in some areas, baseboard in others, plenty of hot
water for the eight showers, and no snow on the steps or sidewalks.
