By design, Taco Comfort Solutions’ new Project Builder 2.0 design tool helps commercial hydronic engineers and designers to quickly select the right products and assemble all related documents into one complete project file.

 The 2024 USHGC addresses the latest provisions and technology paving the road to zero net energy and for the safe installation of solar, hydronics and geothermal energy systems.

Due to its low efficiency and high emissions, an installer is asked to replace the outdoor wood-fired furnace with a new cordwood gasification boiler.

Save time and money with easy-to-install panels that seamlessly integrate into any radiant flooring system.

In 2024, the RPA held educational sessions at the ASHRAE/AHR Expo in Chicago, welcoming new members and setting goals to advance the radiant and hydronics industry.

Take a look at the two photos in Figure 1. Do you see any installation practices that might compromise the eventual structural or thermal performance of this slab?

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 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.

A hydronics newbie decides that he can eliminate the temperature drop effect by putting all three supply-side tees upstream of all three return-side tees. If you don’t think it will work, what would you do to change it?

An installer inspects a system where an aging steam boiler supplies several cast-iron radiators. He proposes to convert the system from steam to hot water and replace the old boiler with a mod/con boiler. Can you spot some potential problems and suggest some improvements?
