Hydronic heating professionals often promote the concept that current generation mod/con boilers can operate with AFUEs in the range of 95% and above. 

There have been numerous studies over the years touting all the benefits of hydronic heating systems, including improved comfort and energy efficiency. 

Anyone who says they wouldn’t change a thing on the hydronic systems they’ve designed or installed over the last decade is either so oblivious to changes in technology that they don’t know any better, so egotistical they can’t accept that improvement of their work is possible, or so foolish they don’t care what they’re missing out on.

Rheem’s Professional Prestige combination boiler is the latest innovation to the company’s high-efficiency tankless gas water heater lineup.

Few would argue that fin-tube baseboard was the “flagship” heat emitter in North American hydronic heating systems through much of the 20th century. 

We are proud to present the first in a four-part eBook series that chronicles Dave’s “Adventures in Hydronic Heating.” 

The CREST condensing boiler upgrade provides up to 96% thermal efficiency in six models ranging from 2.5 MBtu/h to 6 MBtu/h. 

One of the benefits of modern hydronic heating is the ability to use multiple types of heat emitters in the same system. 

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.
