The passage of the Infrastructure Investment and Jobs Act last year will help inject billions of dollars into both potable water and wastewater upgrades over the next several years. 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.
Scald protection valves are the last line of defense in protecting occupants from dangerously hot water in plumbing systems. Point-of-use mixing valves keep building occupants safe and enable a variety of important domestic hot water recirculation applications. How are designers using scald protection mixing valves to advance the broader topic of DHW recirculation?
What does a looming housing shortage, a significant increase in energy prices and 52% of home buyers ready to heat and cool their homes with electricity have in common? They’re all remedied in the same way: All-geothermal residential developments.
It’s not unusual for folks to wax and wane during conversations about experiences that we have had or read about that push the limits of our experience. When I worked as a pump applications engineer, I used to pour over the catalogs and pump curves of all the various manufacturers and think about what each type of pump was capable of.
