Radiant heating and cooling systems are not new to the North American market, but there’s a strong trend toward incorporating both, especially for tightly controlled environments such as commercial spaces.

The NextGen Boiler is a hydronic appliance that when installed, allows the homeowner to have peace of mind about their radiant heat applications.

Circulating ground-temperature water in a Thermal Energy Network (TEN) provides efficient heating and cooling, reducing costs and mitigating climate change through decarbonization. The water must be kept within a specific temperature range, known as the performance zone.

The event’s more than 100 technical sessions will showcase on eight conference tracks will offer emerging approaches to building design, construction and operation.

The East Coast has suffered severe damage from Hurricanes Helene and Milton, leading to extensive destruction, fatalities, and power outages. These hurricanes highlight the impact of climate change on storm severity, driven by warmer Atlantic waters. This situation underscores the urgent need for the PHCP-PVF industry to adapt to the challenges of increasingly intense storms.

Heating contractors attended the event to learn about high-efficiency heating equipment, including the Ambient Air-to-Water Heat Pump, Citadel commercial condensing boiler, Alta self-adaptive boiler, and the Ambient electric boiler.  

The event also offered ASPE-accredited Continuing Education Units (CEUs), enhancing participants' knowledge and professional development.

 The 71st Annual Meeting of the Membership will be held as part of the PMI25 Manufacturing Success Conference from Nov. 3-6, 2025, at the Fairmont Hotel in Chicago. 

My technical boiler books all use the “lessons learned” theme, and the following are the lessons I have learned about boiler water treatment.

It was such a simple project; replace the old cast iron boiler with a new condensing boiler. You knocked it out in a few days. 

On the older hydronic systems, replacing the existing boiler with a new one was pretty straightforward. The installer connected the new boiler to the existing flue, piping and electric. The newer high-efficiency boilers are much different and require some additional planning.

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

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 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.

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.
