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.

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…

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

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.

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. 

Many legacy hydronic heating systems use a fossil fuel boiler to supply fin-tube baseboard heat emitters in some areas of a building and lower-temperature radiant panels in other areas. 

Government planners, taking their queues from politicians and advocacy organizations, have steered the future of energy supply away from fossil fuels and toward renewably-sourced electricity. It’s happening on every level from the feds right down to local city councils.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.

Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

Several years ago, I had the opportunity of visiting the Mostra Convegno Expocomfort show in Milan, Italy. It ranks right up there with the famous ISH show in Frankfurt, Germany, as a “bucket list” event for those who are passionate about hydronic heating and plumbing.

The basics of relays and switches - part one.

The new Market District Apartments in Ohio City will be located near the historic West Side Market, the oldest operating indoor/outdoor market space in Cleveland. Currently, the 13-story development is the largest sustainable, wood-constructed building in the country. Among other facilities, the new 385-unit structure encompasses a first-floor retail space, residential suites on floors two through seven and luxury penthouse suites on the ninth floor, as well as amenity space, including a large rental hall.

Selected as one of 33 projects in the U.S., the funding will be matched by Kohler investment to support the Electric Boiler & Microgrid project at its manufacturing site in Casa Grande, Arizona.

Strategic move underscores Meyers’ commitment to expanding its footprint in the folding cartons sector.

Why is it that your staff isn’t quite as excited as you are when you discuss a new project, a new process, new policy or a habit you want to change?

The code-writing organizations are currently finalizing the 2021 edition of the Plumbing Code, which may be adopted in your state or local jurisdiction by 2023. That is how far in advance hot subjects that are being discussed now wait before becoming law.

As a backpacker, the most important item I carry in my backpack is water. I start each morning of a hike with three liters of water; two in my bladder and one in my bottle. The water bottle looks like any typical water bottle that people carry.

Elegance is the name of the game with modern bathrooms. To keep up with the demands of the public, the plumbing codes and standards have changed regarding modern bathrooms. Some changes are for the good; others, well, we will have to see.

The baby boomer generation is reaching retirement age, and many are planning to age in place. As the body ages, the use of plumbing fixtures changes. The aging body no longer has the strength and flexibility of the younger body.

People distracted by their cellphones are tripping, falling and hurting their heads and necks more often, with such injuries increasing “steeply” over a 20-year period, a new analysis has found.

ISHN Magazine sat down with Joe Boyle, CEO of TRUCE, to discuss strategies for eliminating workplace distractions. The following are excerpts from that conversation.

Accidents happen for millions of reasons, but the truth is, they are all preventable. Three major causes are common in almost all accidents; not using the right tool for the job; using a damaged tool that hasn’t been inspected; and not following the basic safety guideline for that tool.

Since mind not on task is bound to happen if you know how to do something well, there is much more “leverage” or efficiency in getting people to put more effort than they are currently making (none) into improving their safety-related habits.

Every year, AdvisorSmith researches the most dangerous jobs in the United States based on data from the U.S. Bureau of Labor Statistics Census of Fatal Occupational Injuries.
