An installer is asked to pipe up two larger commercial air handlers supplied by a dual boiler sub-system. The building owner wants to make it possible to supply either air handler from either boiler. Can you spot some shortcomings and suggest a better way to accomplish the same objectives?
The medical profession confronts dual challenges: ensuring positive outcomes for patients while tackling the prevalence of healthcare-associated infections. Healthcare management is deeply focused on addressing these critical issues.

The installer is tasked with setting up a three-zone radiant floor heating system using a 5-ton geothermal heat pump and a mod/con boiler, connected through a primary-secondary system with closely spaced tees. The system includes 4 earth loops of 1” HDPE tubing, each 500 feet long, supplying the heat pump, and features underfloor tubing with aluminum plates.
