Two engineers mine their collective experience for tips on designing, modeling, and operating hydronic radiant heating and cooling systems. From conceptual basics to control nuances, on to goals like maximizing deadband operation or deploying a hybrid system, the article circulates plenty of practical information for an array of radiant opportunities.
Effective hydronics, like many things in life, is about maintaining balance. Learn more about achieving the three key conditions necessary for giving your modern controller a fighting chance to do its job.
This large complex is welcoming a host of new arrivals, from new boilers and chillers to an
overhaul of its hydronic strategy. Avoiding a whole lot of drilling was one benefit of their new design choice. Balancing first cost, maintenance costs, and the system itself were additional positives for keeping all 225 units comfortable and affordable.
system experts see flow as a key step to optimizing system efficiency. Cutting
down required tubing size, insulated PEX for district systems, and
variable-speed pumps to pin down a chiller’s exact needs are three points of
attack in the modern campaign against waste.
Having lived with an ancient heating system and no cooling for years, a
Pennsylvania congregation now sings the praises of the updated
hydronics and new mini-splits that brought a mechanical renaissance
to the church’s various spaces.
From a missing pipe hanger three floors down to steam traps past their prime, these stories show how steam system problems can originate inside the boiler room or far beyond it. Read more in February issue.
