An installer is asked to add a monobloc-style air-to-water heat pump to an existing hydronic system that is supplied by a mod/con boiler.

A homeowner posted a question on The Wall at HeatingHelp.com about a drumroll sound that was coming from his brand-new steam boiler. What could it be? He included a video so all could hear, and sure enough, it sounded like a snare drum.

A technician encounters a system installed in the 1980s when radiant floor heating was relatively new in North America.

In March 2010, a nine-month-old boy rolled off his sister’s bed in Jersey City, New Jersey, and got stuck between the bed and a cast-iron, steam radiator that was as hot as it’s supposed to be. The radiator delivered third-degree burns to the infant and left him with permanent scars.

A multiple boiler system using sectional cast-iron boilers has been configured to supply two loads as shown below. A “crossover pipe” is installed in case the flow rate in the primary circuit is different from the flow through the boilers. There are several piping errors in this proposed design. Can you spot at least five of them?

One of the most recent initiatives undertaken by the Radiant Professionals Alliance Hydronics Industry Alliance — Commercial (HIA-C) committee is designed to create interest in the Hydronic University and introduce the future “Hydronic Solutions” videos and tutorials, white papers and training.
