A summer day-trip to a historial building leads to an exploration of healthcare heating systems in a blog by Krista Biason on the HGA website

The James J. Hill House in St. Paul, Minn., completed in 1891, boasts a number of interesting features, but most impressive is its original engineering systems, according to the blog. The house has a "security" system of window entry contacts, indoor plumbing, dual gas and electrical light fixtures and a heating system comprised of boilers, heat exchangers and convection heating.

"I did not realize how advanced the house's heating system was until I talked with Stan Pehling, a member of HGA's mechanical engineering group," Biason wrote.

Even though the convection heating design concept was not embraced by the healthcare industry until the late 1800s, it is still a common design for many healthcare projects today.
