Sleeping easier: Vermont hotel’s pump retrofit gives peace to both patrons and facility manager
Kevin Amyot had serious qualms last spring when contractor Ed Friedrich first proposed a major pump-retrofit project at the Sunset Motor Inn, one of the properties Amyot manages for the H. A. Manosh Corporation in Morrisville, VT. Friedrich’s $13,000 estimate called for the replacement of 18 fixed-speed circulating pumps in the heating system at the Sunset with 10 circulators from the Grundfos Pumps Corporation.
Six of the pumps would be conventional, fixed-speed circulators. But the remaining four replacement units would be energy-saving, variable-speed, “smart” circulators. This quartet coupled ECM (electronically commutated motor) technology with sophisticated electronics for matching pump output to changing system demand — automatically and without human intervention — delivering substantial energy savings in the process.
