Dan Worm Talks Prefab, Kitting, and Mechanical Systems on Building HVAC Science Podcast
By Maddy Dolby
In “Pipe, Pumps & Prefab Rethinking How Mechanical Systems Get Built,” Worm shares how his carpentry background shapes the way he looks at mechanical systems. Rather than focusing on individual components, he looks at how they work together in a building and fit into the overall construction process.
Worm explains how there has been a lot of evolution with code on the potable water side of the business, especially within the past 10 years. This has specifically impacted the hot water side of things regarding energy efficiency, insulation, as well as legionella and Legionaries’ disease.
“The big part of this really comes down to system design.” Worm shares. “It’s not necessarily piping materials. A lot of it is design related…”
Worm also discusses how prefabrication and kitting can improve jobsite efficiency. Prefabricated PEX pipe and kitting can shorten installation time, improve consistency, reduce missed connections, and simplify inventory management.
“Ultimately what it’s doing is making jobsites run smoother and it’s making contractors more profitable,” Worm says. “There really are no negatives to it.”
Worm and Spohn also explore hydronic heating and cooling, including why low-temperature radiant systems can pair well with heat pumps and why radiant cooling brings another major variable into the picture: dew point and condensation control.
