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’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…

The MagnaClean Professional2XP comes with 1” copper and 1 1/4” NPT iron pipework, perfect for protecting 150,000 – 300,000 Btu boiler ranges from damaging black sludge.

Heating experts have long touted hydronics as the far superior comfort technology over forced air due to better operational efficiencies and improved comfort. According to Research and Markets, the global hydronic systems market is poised to grow $1.3 billion from 2021-2025, driven by the growing need for energy-efficient cooling and heating systems and increase in construction activities worldwide.

The choice between ∆T and ∆P operation of a circulator has, at times, been the subject of rather “heated” debates. It’s almost as if a few Yankee fans are disputing superior pitching or batting performance with a few Red Sox fans. There appears to be some strong opinions involved.

As building codes and programs such as Energy Star and Passive House require higher degrees of air sealing in new construction, the use of heat recovery ventilation (HRV) is increasing.

If you’re anything like me, the first thing that comes to mind when you think about variable speed circulators is 1970s rock band Supertramp. No? Okay, maybe you’re not like me. Either way, allow me to elucidate.

Nearly all closed-loop hydronic heating and cooling systems are supposed to be filled with water or a mixture of water and antifreeze. The only intentional air in the system is that contained in the expansion tank.

As residential building codes and energy conservation standards continue to evolve, many are requiring proof of high quality air sealing.

Over the last few years, I’ve written several columns describing how air-to-water heat pumps can provide heating, cooling and domestic hot water for homes. Many of the systems involve buffer tanks to help stabilize heat transfer from the heat pump to a zoned distribution system.
