TacoTherm Fresh Mega

Fresh water station for hygienically heating drinking water in accordance with the cyclical principle with and without circulation

Description

  • The TacoTherm Fresh Mega fresh 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, solid fuel 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

Advantages

Compact

  • Equipped with all the necessary valves and components, ideally complements the TacoSol Load Mega storage loading station

Secure

  • Intrinsic safety of the system thanks to an integrated safety subassembly
  • Protection against Legionella by avoiding water stagnation

Simple

  • Station is fully preassembled and supplied with ready-to-connect wiring

Efficient (ErP-Ready)

  • Highly efficient system operation owing to the use of high efficiency pumps.

Functions

  • Drinking water is heated to the required dispensing temperature in the TacoTherm Fresh Mega in accordance with the cyclical principle. The integrated heat exchanger is supplied with as little hot water from the storage tank as is required to maintain a constant dispensing temperature.
  • A low return temperature of the heating water to the storage tank can be expected owing to the special design of the heat exchanger. In recording the temperature difference and flow rate data, the electronic regulator simultaneously records and stores the quantity of heat consumed.
