Abstract

A system for controlling water delivery throughout a household water delivery network that includes bathroom and kitchen sinks, as well as other equipment for dispensing water, said system including a controller disposed at a site, the temperature of the water of which is to be controlled; said controller including a temperature probe for detecting the water temperature at the site; a pump for circulating water from a water heater to the site; and a wireless communication network that interconnects the controller with the pump in order to control hot water delivered from the water heater based on sensed temperature at the temperature probe. Also a process for controlling the water temperature of a water delivery system that includes a pump, either via a wifi hub or a system APP. Also disclosed is a novel adjustment ring associated with the valve.

Claims12

Dependent claims

A recirculation valve for use with a water heater in a system that includes hot and cold water fixtures and a cold water supply, said recirculation valve comprising:

a valve body having multiple connections in the form of a tee structure that has an internal chamber;
a thermostatic element that is at least partially disposed in the internal chamber of the valve body;
said thermostatic element including a support base constructed and arranged within the valve body and a thermal actuation piston that is responsive to water temperature within the valve body;
said thermal actuation piston constructed and arranged to have a retracted position in which the thermal actuation piston is retracted into the support base, and an extended position in which the thermal actuation piston extends longitudinally away from the support base;
a cap piece that engages with the thermal actuation piston;
an end adjustment ring that engages with the valve body and that includes a center hole;
said adjustment ring adapted for engagement with the cap piece to either open or close the hole in the adjustment ring in order to maintain a predetermined temperature.
