Think you know pump systems? Think again. From misidentifying the major culprits of ownership costs to taking the wrong approach in implementing variable speed drives, misconceptions around pumps create missed opportunities for greater efficiency and cost savings.
In business, a decision based on incorrect information can have far-reaching consequences for an organization. This is not breaking news, of course, but consider this: Autodesk recently released a study in collaboration with consulting firm FMI Corp. on the prevalence of data usage in construction and the repercussions associated with data errors.

Coupled with that, President Joe Biden has issued an executive order and Federal Sustainability Plan that will put the U.S. federal government on a path to reach net-zero emissions by 2050, which includes directives for federal buildings and facilities to achieve net-zero emissions by 2045 through energy efficiency, electrification and use of carbon-free electricity along with sustainability principles.
On the older hydronic systems, replacing the existing boiler with a new one was pretty straightforward. The installer connected the new boiler to the existing flue, piping and electric. The newer high-efficiency boilers are much different and require some additional planning.
This month I want to deviate a bit from a purely renewable energy topic to one that’s important across the entire spectrum of hydronics technology. It’s a topic that likely gets exercised on a daily basis in any engineering office where water-based HVAC systems are conceived.
My first encounter in dealing with combating Legionnaires’ disease through code regulations dates back to 1977. Older individuals will recall that the disease got its name after the outbreak in 1976 in Philadelphia at the American Legion Convention.
