TacoTherm Fresh Tera

Fresh hot water station for hygienically heating drinking water in accordance with the continuous flow principle with and without dual-zone return stratification of the storage tank.

Description

The TacoTherm Fresh Tera C/CL fresh water station is used for on-demand preparation of domestic hot water in accordance with the continuous flow principle. It retrieves the heat from the storage tank of an existing or new heating system, which uses solid-fuel boilers, heat pumps, solar systems, etc. as a heat source. The station replaces the storage of hot drinking water 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 Tera 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 with ready-to-connect wiring

Efficient

  • Highly efficient system operation owing to the use of HE pumps and stable storage tank stratification

Functions

  • Drinking water is heated to the defined dispensing temperature in the TacoTherm Fresh Tera in accordance with the continuous flow 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.
  • The TacoTherm Fresh Tera can be supplied optionally with a switching valve for storage stratification. This pump and also the load valve are controlled by the integrated regulation system by means of a separate program.
