Blake Rosenberg is an inspired plumbing and hydronic pro in the Northern Massachusetts area who readily admits that his inspiration and success stem from the influence of a special mentor. Well, two of them.
Although the market for solar thermal systems is a tiny fraction of what it once was, I still believe there are viable applications that could help in decarbonizing thermal energy systems.
Last month, we covered the basics of classifying switches and relays based on poles and throws. Once you learn these, it’s easy to apply switches and relays to create “hard-wired” control logic - part two.
Historically specified and installed as radiant heating and cooling or snow- and ice-melting systems pipe, PEX is now trending as a viable hydronic distribution pipe for heating hot water and chilled water applications.
Several years ago, I had the opportunity of visiting the Mostra Convegno Expocomfort show in Milan, Italy. It ranks right up there with the famous ISH show in Frankfurt, Germany, as a “bucket list” event for those who are passionate about hydronic heating and plumbing.
Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.
The very first installation of the Mikrofill 3 hydronic pressurization unit in North America took place recently in a mechanical room of an assisted- and independent-living community in Southwest-suburban Chicago. You might say the flower of this innovation grew from the soil of an old industry friendship.
More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.
Many hydronic installers look for ways to differentiate their work, to craft a specific look — maybe even a “brand” — that resonates with customers. For Fernando Lobo, owner of Fairfield, Connecticut-based 1 Call Services, that unique look begins with the raw material list he builds when sizing a boiler replacement, or new boiler install.
This webinar will show you four different methods for providing hydraulic separation, some of which may reduce the installation and operating cost of a system.
