The Oregon Zoo's new Veterinary Medical Center required a climate-controlled intensive care unit in order to provide service to a variety of species. The zoo decided that installing Buderus solar thermal water heating and condensing gas boilers for hydronic radiant heat would be the best choice for both the animals' well-being as well as the environment.

After completing a state-sponsored energy audit at this historic 1927 diner, Dan Beck, one of the family owners, did some research and found that by replacing the existing oil-fired boiler with a high-efficiency gas condensing boiler, he could save a significant amount on annual fuel costs.

The Caroline is one of the most prestigious residential apartment buildings in New York City. The 20-story building features 433 apartments with premium kitchen and bath amenities, 50-foot sky-lit swimming pool, on-site laundry, fitness center and central climate control. Built in 2000, the building used a central hot water delivery system using four commercial direct fired water heaters. The building owners upgraded to Bosch condensing tankless water heaters to save space and energy costs.
