The Hercules Cryo-Tek original antifreeze is designed for use in hydronic heating and cooling closed-loop systems, most solar heating systems, snow melts, radiant heating, and general plumbing systems. 

I’m sure everyone reading this column has heard the adage “a picture is worth a thousand words.”  

The classic way of estimating heating load in smaller, envelope-dominated buildings is to assume the rate of heat loss is proportional to the difference between the inside and outside temperature.

In last month’s column, I presented a “template” for a system that provides space heating, cooling and domestic water heating using a cold climate air-to-water heat pump as the primary heat source, and the sole source of chilled water for cooling. 

For decades, fossil-fueled boilers have dominated the market for hydronic heat sources.

Most of the modern hydronics technology used in North America for residential and light commercial buildings is for heating. 

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

Armstrong Fluid Technology will introduced the enhanced Design Envelope IPC 9521 integrated plant control system at AHR Expo.
