H₂O Accepted is a new initiative of the HIA-C, designed to showcase the advantages of water-based (hydronic) commercial building space heating and cooling technologies.

Figure 1 shows a hydronic system that's intended to supply four panel radiators, each with its own thermostatic radiator valve, and an indirect water heater from a gas-fired sectional cast-iron boiler.

Taco Comfort Solutions’ new 4900 series magnetic dirt separator provides dual-action dirt separation for closed-loop hydronic heating systems. 

The Spirocombi Magnet is a high-efficiency, coalescing-type combination air eliminator and dirt separator for use in hydronic systems.

With global concerns of water scarcity, lack of clean water access and efficient use of water in business and industry, a new Xylem podcast called “Solving Water” is a resource for water professionals to learn more about these vital issues.

When water is heated, the space required for each molecule increases. Any attempt to prevent this expansion will be met by tremendous forces.

The owner asked for a bid to replace her 35-year-old cast iron boiler which was still operating. She had two requirements: Redundancy in the event of a boiler malfunction and lower fuel costs for the building.

When John Kopf eventually gets around to designing and building his own house, he will go with hydronic heat instead of a more traditional forced air system. Kopf knows a thing or two about heating, having spent more than 20 years in the industry. He currently serves as boiler product manager for Navien.

Over the years, our office has received requests for design assistance for systems involving two hydronic heat sources, each in different buildings, where the expectation is to have either heat source supply heat to either building.

The new zone valve comes in ½”, ¾”, and 1” sizes.
