In a different way from normal domestic water, domestic water as food is not used for energy storage and stored for hours. An efficient plate heat exchanger heats it when necessary. The energy for heating the domestic water comes from a buffer storage tank which can be heated by various systems: solar installations as well as solid combustibles, conventional oil or gas boilers or other systems. FriwaMini The Friwa modules are very well suited for the application in a solar thermal installation. The excellent cooling of heating water in the efficient plate heat exchanger improves the efficiency of the solar circuit as the cold return reduces the medium temperature of the solar circuit. In case of large withdrawal differences the Friwa modules guarantee a constant outlet temperature at the hot water tap. The efficient control optimally sets the current withdrawal capacity of the heating flow rate by means of high-efficiency speed-controlled EC pumps. The control receives the required information to control the system via a new developed ultrasonic flow rate sensor and rapid temperature sensors, which immediately detect smallest temperature differences. The circulation pumps used in the Friwa modules meet the energy efficiency guidelines (EuP / ErP READY) of 2015. The control operates the pumps in different circulation modes which are adapted to the individual customer system requirements. FriwaMidi / FriwaMaxi Of course the Friwa modules correspond to the requirements of the German Drinking Water Ordinance (TrinkwV 2011). The required flame-treated valves can be mounted in the Friwa, thus there is no need for an external withdrawal. You can set the circulation return temperature individually during commissioning, so that the DVGW 551 requirements (German association for gas and water) of a maximum circulation cooling of 5 K are met in a transparent way and can be logged. The Friwa modules offer you a perfect comfort, optimum hygiene and a forward-looking energy saving operation. FriwaMega 136 04/2014 • Printed in Germany PAW GmbH & Co.

The demand of hot water depends on the flow and the number of consumers. In larger apartment buildings a statistic distribution of withdrawals can be detected. The following table shows a basic overview of the application range of Friwa module variants.

The control functions are adjusted continuously during operation to the system conditions via an autoadaptive algorithm. The operation of the return distribution valve is an additional function of the controller. Different operating modes are possible which can be adapted to the system requirements. The pumps are actuated via a PWM signal. An output for switching the return distribution valve is available. Self-explanatory pictograms indicate the active controller mode.
