High-efficiency boiler provides flexibility

Combination gas-condensing FLOOR-STANDING boiler provides efficient service

Problem: A 2,000-square-foot single-family home in southern New Hampshire had used an existing forced air heating system. The homeowner, James Middleton, decided to upgrade to hydronic heat but needed a system that was compact and easy to install.
 
Solution: Installation included Buderus panel radiators and Bosch Greenstar FS floor-standing gas-condensing combination boiler from Bosch Thermotechnology Corp. to provide comfortable heating and on-demand hot water. The combination units are ideal for use in applications where wall-mounting options are not available or a floor-standing unit is preferred. All boiler models have an ENERGY STAR Most Efficient rating of 95 percent.

Result: “I’ve installed a lot of Buderus oil-fired floor boilers, but this is my first Greenstar installation,” says installer Jason Wetherbee. “I’m impressed with how compact and relatively easy to place it is. The integrated low-loss header is pre-piped so there’s no need for primary/secondary piping, and venting is simplified with polypropylene, PVC or CPVC.” 800/283-3787; www.boschheatingandcooling.com.


High-efficiency boiler provides flexibility

Problem: AAA Plumbing & Heating of Pueblo, Colorado, was brought on during the design phase of a 2,600-square-foot residential construction project. The customer wanted maximum efficiency and environmental sustainability without sacrificing comfort. Despite being a custom home, the homeowners were looking for a value design. With tile and hardwood floors throughout the structure, they were hoping to find an in-floor radiant system that was within their budget.

Solution: The heating contractor designed a six-zone hydronic radiant system around a 180 mbh U.S. Boiler Company K2 condensing boiler. With a stainless steel heat exchanger and efficiencies of up to 95 percent, the system offers flexibility and efficiency. Material and operating costs were trimmed by zoning with a single variable-speed circulator and zone valves.

Result: After a Colorado winter, the customers are thrilled with the comfort provided by the in-floor system and low operating costs. The K2 Boiler System accessory package adds flexibility with a pre-manufactured primary/secondary loop, zone control, combination kit and a wireless outdoor reset control. 888/432-8887; www.k2boiler.com.
