The year-long Caleffi Excellence contest — which is a platform where designers and installers of hydronic or plumbing systems can showcase their work — has culminated in the announcement of the grand prize winner.

Bill Olschewski of Tip Top Plumbing (Manitoba, Canada) and a guest of his choice has won a trip to Italy to see Caleffi World Headquarters and will receive a personalized tour of Caleffi's factories and design facilities.

The top twelve monthly finalists, as determined by most votes received from the popular Coffee with Caleffi webinar series, received an iPad mini. Olschewski’s installation was selected from a panel of industry experts and Caleffi executives. His mechanical room upgrade included creating five zones using Caleffi zone valve and relay controls to simplify programming and wiring for a homeowner’s combination heating/cooling and domestic hot water system.

The Excellence contest resumes on Jan. 1, 2016. Visit for contest details.
