As noted in Part I and Part II of this series (see HPAC February and March 2018), control systems are often blamed when something is not operating as expected. More often than not, if control systems do not perform as…
Equipment change out impacted by space, venting and timing issues. Friends of mine were recently faced with a decision when their combination boiler/DHW heater refused to provide either. Now this should not have come as a complete surprise as the…
Over the course of your career you have probably used a number of strategies to compete for projects. Maybe your choice de jour was to do battle using a lowest price model. Maybe you got tired of dealing with headaches…
As it was noted in Part I of this series (see HPAC February 2018), control systems are often blamed when something is not operating as expected. More often than not, if control systems do not perform as needed, something…

What characteristic do solar thermal collectors, hydronic heat pumps and thermal storage tanks supplied by biomass boilers have in common? Answer: They all perform best when coupled to distribution systems that operate at low supply water temperatures. But that is…
Controls are often blamed when hydronic systems are not operating properly. While that may sometimes be the case, always look at what else may be influencing performance. While control systems are not flawless, consider that they are developed in a…
In Lowering the bar–part I, we discussed how to size supplemental heat emitters that allow the supply water temperature to an existing distribution system to be reduced. The next step is to pipe those supplemental heat emitters into the existing…
Stop by HPAC’s booth at the top of the escalator on March 21 (opening day) for your chance to win Viega’s flameless press technology system. It reduces installation time and enables installers to make press connections in difficult-to-reach areas and…
