The T-QUICK is an instantaneous domestic hot water production module using a brazed stainless steel plate heat exchanger. The domestic hot water temperature is regulated by means of a three-way thermostatic mixing valve installed on the primary circuit (thermal storage side). The module, connected to a thermal storage tank from which it draws energy, is complete with all the components necessary for its operation: a pump on the primary circuit operated by a flow switch positioned on the inlet of the DHW circuit, a mixing valve operated by a thermostatic actuator, which allows the user to keep the set DHW temperature constant. For maximum user comfort, accessories are available for hot water recirculation management that can be combined with each other or used individually according to one's needs.
