A review of a flawed hydronic heating system uncovers critical errors, such as improper circulator placement and restrictive mixing valves, leading to uneven warmth and corrosion issues. This underscores the need for proper design and installation in hydronic systems.

A hotel’s aging hot water system faces upgrades as leaking tanks are set to be replaced with smaller units. While a full redesign is desired for efficiency, budget constraints may limit the project scope, causing temporary hot water disruptions.

The photo in Figure 1 shows a non-pressurized outdoor wood-fired furnace connected to a floor heating subsystem via two PEX tubes. It includes a cast iron circulator, a thermostatic 3-way valve for mixing, a bypass linking supply and return tubes, and an "expansion zone" for another floor heating circuit. This setup is in a multi-million dollar home. Are there any potential issues with the installation?

The deadline to apply is Dec. 6.

The award is presented every two years to a nominee with attributes including technical mastery and a passion for hydronic technologies, demonstrated leadership as an educator and mentor, and an aptitude for cultivating fundraising opportunities for industry causes.

A project needs medium- and low-temperature radiant floor panels. The installer proposes using a mod/con boiler with a 1-inch tempering valve for lower temperatures and plans to pipe the entire system with 1-inch tubing. What potential issues could arise from this design?

Caleffi's new AutoFill has a fill rate of 5.5 GPM and maintains stable system pressure, ensuring consistent results without the need for constant monitoring.

This second edition of the Radiant & Hydronics All Stars eBook showcases the latest technology and design trends in the radiant and hydronic markets. It features insights from our All Star Roundtable on low-temperature systems and upcoming efficiency standards for circulator pumps by 2028, along with design trends for residential and commercial applications.

Always assume the old boiler was installed wrong. This principle has served me well in my career by finding problems before we own the system.

Junkyards are one of those forgotten places we in the heating business must visit on occasion.
