The city of Amboy, Ill. needed an in-floor radiant heating and domestic hot water (DHW) system, and Grasser’s Plumbing and Heating was more than happy to oblige. Grassers has been making customers happy for over a half of a century. In fact, and they have become one of the most successful and trusted plumbing and heating companies in the LaSalle, Peru, Princeton and Ottawa, Illinois area for more than 60 years.

According to tech Tim Kuhlman—who works mostly high-end new construction and commercial jobs—the city of Amboy needed radiant heat for one of its 4,000-sq.-ft. “sheds,” which is used for the maintenance of city vehicles and storage, and domestic hot water for a service sink.

The hot water solution was a primary/secondary piping application and provided by an NTI Ti200AC Trinity combi boiler, which features a state-of-the-art sealed modulation combustion system with hot surface ignition and patented 316L stainless condensing heat exchanger provides higher efficiencies. The combi boiler supplies heat to stainless steel Viega radiant manifolds—with shutoff and balancing/flow meters—which feeds Viega’s PEX tubing in the floor, and it also supplies domestic hot water for the service sink.
