Hydronics


Hydronic heating systems use water to move heat from where it is produced to where it is needed. The water within the system is neither the source of the heat nor its destination; only its “conveyor belt.” Heat is absorbed by the water at a heat source, conveyed by the water through the distribution piping, and finally released into a heated space by a heat emitter.

John Siegenthaler Investigates: Low Ambient Air-to-Water Heat Pumps

Low Ambient Air-to-Water Heat Pumps: An emerging renewable heat source for North American hydronic systems.
Electrically powered heat pumps, in many varieties, are destined to play an increasingly important role in heating and cooling buildings around the world.

Heat pumps capture low grade heat from solar-resupplied sources such as outside air and soil several feet below the earth’s […]

Radiant Heating Case Studies: Ceiling Panels & Injection Piping

Expert instructor Dave Yates answers student questions with customer anecdotes on the Fundamentals of Radiant Heating discussion board
Student 1: I’ve seen two references in the course to “high temperature” ceiling panels needing to be at least 8 feet above the floor. Is this to prevent children from touching them, or is it to limit the heat in […]

Site Assessment for Solar Hot Water Heating Systems

Without a proper site assessment, you may be putting your solar thermal system at risk for poor performance…

It is a fairly common occurrence for a solar professional to hear from a potential client, “We get tons of sun,” or “Our roof faces due south,” and then […]

HVAC Engineering: Chilled Floors + Humidity

On the Integrated HVAC Engineering discussion board, expert Robert Bean answers questions about chilled floors and humidity considerations and air mixing…
Student 1:  
Chilled floors seems like a great idea, and if you’re going to do a radiant system, you might as well consider cooling and heating.

The humidity, however, seems to be a big concern. Vapor barriers […]
