TacoTherm Fresh Mega Connect

Fresh hot water station for hygienically heating drinking water in accordance with the continuous flow principle with innovative pump and regulation technology

Description

The TacoTherm Fresh Mega Connect fresh hot water station is used for heating drinking water on demand in accordance with the cyclical principle in conjunction with a storage tank for existing and new heating systems, wood-burning boilers, heat pumps and solar systems. The station replaces the storage of hot drinking water in an additional storage unit and thus provides a high degree of protection against Legionella by avoiding water stagnation.
