By now, most of you have either installed inverter-driven variable speed heat pumps that can deliver their nominal rating output at temperatures well below 0° F without any backup heat source, or at least have become familiar with the technology. 

When a crew in Maine needed to renovate the heating system in an elementary school, they were up against two challenges — time and cleanliness.

In order to achieve a more environmentally friendly footprint for its new education and research campus in Narre Warren, Australia, IAPMO and the Plumbing Industry Climate Action Centre (PICAC) chose one technology rooted quite literally in the earth.

While the history of radiant heating stretches all the way back to the Roman hypocausts more than 2,000 years ago, the technology is still growing in popularity today.

In August, IAPMO and the Hydronics Industry Alliance – Commercial (HIA-C) presented the inaugural Les Nelson Achievement Award to the late leader of IAPMO’s Advanced Energy Systems’ widow and two children during a ceremony broadcast online from World Headquarters West in Ontario, California.

A little over eight years ago, The IAPMO Group purchased the assets of the Radiant Panel Association. 

It is a difficult time to be discussing the status of the radiant and hydronics industry (and for that matter the entire construction industry). 

The Belanus residence was started in 2013. Our company, Arndt & Son Plumbing, began our work in June 2013, and completed the project in December 2014. 

A custom-designed, prefabricated, pre-pressurized network of Uponor crosslinked polyethylene (PEX-a) tubing, the Uponor Radiant Rollout Mat is the ideal solution for faster, more consistent installations for large commercial radiant heating and cooling applications — saving up to 85% in installation time, the company notes. 

The BLF-2 balancing valve allows for precise flow control to ensure efficient energy distribution to match the load of each zone in a hydronic heating or cooling system.
