This system is the missing link between one- and two-pipe steam. It was used in tall buildings in the early 1900s because a building this tall wouldn’t work well with one-pipe steam if the supply came up from the basement. 

A radiant floor heating solution leveraging Polyethylene of Raised Temperature Resistance (PE-RT) technology from The Dow Chemical Company (Dow) is the hy-PE-RTube™.

A tradeoff has always existed between the water temperature at which hydronic heat emitters are sized and their cost. The higher the supply water temperature assumed by the designer, the smaller the required heat emitters and the lower their installed cost. 

Ultra-high efficiency, the Triple-Flex™ Series of hot-water condensing boilers deliver a minimum 90 percent operating efficiency with 160°F return and 180° supply at maximum input. 

The University of Missouri (MU) in Columbia, Mo. is being commended for its commitment to energy reduction and sustainability through the installation of a new biomass boiler. 

A differential pressure sensor has been added to the company’s line of hydronic system components. 

Designed to offer a solution for solar thermal and ground-source applications with an emphasis on hydronic space heating, the multifunctional Thermal-Stor™ stratified solar thermal storage tank operates as a storage tank and hydronic buffer tank while occupying the space of a single unit. 

High efficiency comes with a price that’s higher than normal efficiency (whatever that is), and because of that higher price, high efficiency is now a subjective term that is open to broad interpretation, and perhaps even reinvention. 

The application of wet heat technology has expanded over the years and new technologies that improve control and efficiencies are pushing this industry sector further ahead.
