Radiant system takes load off forced air
The first three floors were specified to include radiant heating and cooling, and Uponor was asked to help with design and product guidance. Working closely with Circulating Air, a Los Angeles-based mechanical contractor, Uponor helped design the system in conjunction with engineers and architects.
“The contractor had not worked with Uponor prior to this project so we helped them get trained and comfortable with our system on site,” said Jacob Ford of Keyline Sales, a local Uponor rep firm. “It didn’t take long for them to catch on, and they quickly advanced and found innovative methods to speed up installation.”
According to Ford, the building’s southern facing is a wall of glass, and the radiant heating and cooling system takes a huge load off the forced air system.
The four-man Circulating Air crew worked closely with Keyline Sales to ensure they installed the 16,000 feet of Uponor’s Wirsbo hePEX™ pipe efficiently.
“We were truly amazed at how quickly and easily we installed the piping for the radiant heating and cooling system,” Matt Fitzgerald, Circulating Air job foreman, said. “Receiving training on site really helped us, and our crew felt up-to-speed very quickly.” Also, Fitzgerald said that prior to training he was unaware how easy it was to make the connections to the manifolds and fittings. “I love how fast and easy the system is,” he said.
Uponor’s Wirsbo hePEX pipe uses ProPEX® expansion fittings which require one simple expander tool to make fast, easy connections that hold tight with up to 1,000 pounds of radial force. For contractors familiar with traditional copper or other rigid pipe connections, the ProPEX fitting system is a much easier, more reliable connection method.
The system hooked up to six manifolds and six cabinets divided between the three lower floors. “The installation was fairly straight forward,” Fitzgerald said. “And we didn’t encounter any obstacles that we couldn’t overcome.”
