Radiant & Hydronics

RSS

The radiant heating market is one that took the industry by storm in the early 2000s. More than two decades later, the acceptance and applications of radiant systems have grown exponentially. Experts describe the radiant heating market in 2022 as “consistent” and “expanding,” citing labor, material and logistic uniformity shortages as the top challenges hindering radiant projects.

During the late, great Les Nelson’s last AHR conference in Chicago back in 2018, he asked me what our hydronics industry needed the most. He was on a mission to increase the visibility of the Radiant Professionals Alliance and give the industry something that it could really use. 

Most hydronic systems have the boiler running up to 180° F with water returning from the system at 160°. This rarely happens in real life, but it’s the traditional way we do things.

 All boilers that burn hydrocarbon fuels such as natural gas, propane, oil or wood produce water vapor as a byproduct of combustion.

Because the price of fuel oil has increased dramatically over the last several months, an installer with lots of experience in installing conventional oil-fired boilers is asked to install a pellet-fired boiler.

Do you work on closed-loop hydronic heating and cooling systems? Does your installation or service include equipment protection? If so, does it include a permanent magnet? If not, it should, and here's why…

I called the plumber because there’s an immediacy to plumbing; and I’m old enough to know that it’s best for me not to touch pipes. To each his own trade.

Grundfos announced the launch of the next generation of small circulators for the residential heating market with the introduction of the Grundfos Digital NEXT range — starting with the UPSe 15-58 in late 2022, followed by the release of the new, digital ALPHA 15-58 in early 2023.

I’ve written it before and I’ll write it again — panel radiators are one of my favorite hydronic heat emitters. I base this sentiment on several benefits. Here are a few to consider…

Imagine that you, an independent heating pro, have been asked to inspect this system because the owner is claiming it doesn’t deliver sufficient heat on cold days.
