Sometimes one less circulator makes sense.

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.
