From Lochinvar Face Book Page – April 2014

The March 2014 winner in the VIP Installation Showcase is Charlie Sarkis of A. Tech Mechanical in Welland, Ontario. His entry described an installation at a 10,000 sq. ft. home with 5 zones of radiant in-floor heating where he says, “Two WHN155 boilers were the choice for both peace of mind and efficiency.” Congrats, Charlie!

The system is installed in a 10,000 Sq. Ft. house in St. Catharines, Ontario with 5 zones of radiant in-floor heat and two high velocity air handlers.

Two Lochinvar Knight boilers were chosen for their “peace of mind” reliability and efficiency. The choice for both model WHN155 Wall Mount Knight Boilers was based on the Smart System Control which is contractor (and customer) friendly with easy to navigate selection screens and cascade feature which allows for multiple temperature zones from one boiler plant. The availability of parts in case of a break down, and the support of the product is second to none!

The fuel source is natural gas and is providing heat at almost 40% less than a house for the same size using a forced air furnace. The installation was based on keeping it simple, primary / secondary piping loop with simple relays used to interlock the pumps for the different temperatures required; 75F for basement, 80F to 95F to the second and third floors and 140F for the air handlers.
