Coffee with Caleffi™
The importance of proper domestic hot water (DHW) temperature control in providing comfort, safety and convenience cannot be overstated. Delivering it remains one of the most important responsibilities of plumbing system designers. Kevin Freidt, Caleffi director of product management and technical support, will discuss temperature control at the hot water source, at the point-of-use, in the balanced secondary circuits and in the system as a whole.
→ What methods are used to control temperature at the DHW source?
→ What is different about controlling hot water temperature at the source vs. at the point-of-use?
→ Mixing valve standards ASSE 1017, ASSE 1070 and other related ASSE standards.
→ Can an instantaneous heater take the place of a mixing valve?
→ Are electronic mixing valves more accurate than thermostatic mixing valves?
→ How do I properly size and install a mixing valve to assure accuracy?
→ What are some causes of the loss of accuracy in a mixing valve?
→ What about temperature control and balancing of secondary piping circuits when I have recirculation?
→ What does accurate temperature control have to do with preventing Legionella bacteria issues?
