The Need to Protect Your High-Efficiency Circulators

摘要

Circulators have been around the Hydronic heating industry dating back to the late 1920s to the early 1930s. They were originally added to existing gravity hot water jobs to "boost" the heat around the system. In fact, Bell & Gossett marketed its circulators as "Booster" pumps because they would move the heat from the boiler to the radiators must faster than simply by gravity.
