High-temperature effluent is directed to storage tanks where it goes through an automated cooling cycle. The cooling obtained by a stainless steel exchanger is tested by a temperature probe. The effluent is evacuated once it has reached the authorized temperature, that is a maximum of 30°C.
A looped network can be formed to recover the calories and thus preheat the cold water intended for the production of Domestic Hot Water (DHW).
