Scald protection valves are the last line of defense in protecting occupants from dangerously hot water in plumbing systems. Point-of-use mixing valves keep building occupants safe and enable a variety of important domestic hot water recirculation applications. How are designers using scald protection mixing valves to advance the broader topic of DHW recirculation?

Hot water has been around since man first harnessed the power of fire, but when at elevated temperatures, it is dangerous and even deadly. Today’s hot water heaters offer a diverse range of technologies that perform leaps and bounds ahead of their predecessors, but what temperature should they deliver?

Domestic hot water recirculation system design is a hot topic in our industry, for good reason. 

Many older commercial facilities today, especially larger, multi-story facilities with plumbing and mechanical systems that may date back 10 or 20 years, have domestic water systems with a consistency problem. 

Preventing scalding is indeed something that requires serious consideration.
