I went to ISH in Frankfurt, Germany with three friends in 1995. 

Some hydronic system designers cling to certain system piping configurations — even when existing projects using those configurations have produced problems.

The results of these votes will be published in the Report on Comments, to be published for review in September.

Anyone who says they wouldn’t change a thing on the hydronic systems they’ve designed or installed over the last decade is either so oblivious to changes in technology that they don’t know any better, so egotistical they can’t accept that improvement of their work is possible, or so foolish they don’t care what they’re missing out on.

Whether designing a residential or commercial system, there are several lessons to be learned from Siegenthaler, a.k.a. “Siggy,” including thermal considerations, piping, heat pump technologies, panel radiators, slab heating, controls and ECM circulators in order to provide the ultimate goals: Comfort, high efficiency and a happy customer.

Part of running any business is looking ahead and trying to read the “tea leaves” that are relevant to that business. 

All HydroSketch users have immediately access to these updates.

Whenever a hydronic system is divided into several zones, it’s worth considering a buffer tank between the heat source and distribution system.
