March VIP winner uses Lochinvar boilers in radiant heating system
The 10,000-sq.-ft. home included five zones of radiant in-floor heating and two high-velocity air handlers.
Lochinvar announced the March winners in its VIP Contractor Program: Charlie Sarkis of A. Tech Mechanical in Welland, Ont., Canada, won the VIP Installation Showcase; and Andrew Vander Zwaag of Macatawa Radiant in Zeeland, Mich., won the monthly drawing. Both winning contractors receive an all-expenses-paid trip for two with tickets to the world’s largest country music festival as part of Lochinvar’s Nashville Experience this June.
Sarkis’ entry (pictured) described an installation at a 10,000-sq.-ft. home in Saint Catharines, Ont. He and his team selected two KNIGHT heating boilers with inputs of 150,000 Btu/hr. for the job, which included five zones of radiant in-floor heating and two high-velocity air handlers. He described the installation as a “primary/secondary loop with a simple relay control to interlock the pumps for the different temperatures between 75° F for the basement, 80° to 95° for the home’s second and third floor, and 140° for when the air handlers are needed.”
