Although I’ve worked with hydronic heating for four decades and designed systems around just about every possible heat source, I would be hard-pressed to predict what might be available as hydronic heat sources 25 years from now. 

Water-to-water heat pumps, supplied from geothermal earth loops, represent a growing sector of the hydronic heat source market. Most current-generation models can produce water temperatures up to about 125° F, perhaps a little higher if you’re willing to push the compressor operating envelope.

District systems, which have been around for centuries, provide buildings with a product created with technology beyond what an individual can either afford or apply. The primary advantage is the delivery of more cost-effective heating or cooling to the building.

The Glycol Make-up Unit GF60 (GMU) automated 110V diaphragm pump with digital control is designed to maintain critical minimum pressure levels to make up for losses that may occur due to leakage.

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

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.
