■■
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 Peta X (C/CL)
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.
INSTALLATION POSITION
Vertical wall-mounting in the vicinity
of the hot water storage tank or on
the tank itself.
OPERATION
Drinking water is heated to the
defined dispensing temperature in
the TacoTherm Fresh Peta X (C/CL)
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 Peta X (C/CL) 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.

EXAMPLE FOR INTERPRETING THE FLOW RATE AND PRESSURE LOSS DIAGRAMS
Given
Hot water dispensing volume:
77 l/min
Primary heating flow temperature:
70 °C
■■
■■
Sought
Hot water demand (l/h)
Primary heating return temperature
in °C
Secondary pressure loss in mbar
Primary pressure loss in mbar
■■
■■
■■
■■
Approach
In Diagram A) the hot water demand
at the intersection point of the
dispensing volume of 77.5 l/min
and primary flow temperature of
70 °C is 4500 l/h.
In Diagram B) the primary pressure
loss for a hot water demand of
4500 l/h is 650 mbar.
The pump delivery head is 750 mbar,
discounting the pressure loss this
gives rise to a residual pump head
of 100 mbar (Δp).
■■
■■
■■
■■
In Diagram C) the primary return
temperature for a given dispensing
volume of 77.5 l/min and the selected flow temperature of 70 °C is
19 °C.
In Diagram D) the secondary
pressure loss for the given data
is 500 mbar

NOTE
The stations heat interface units use a copper-soldered stainless steel plate heat exchanger as standard. It must
be checked prior to use in the framework of system planning whether the issues of corrosion protection and scale
formation have been sufficiently taken into account in accordance with DIN 1988200 and current drinking water
analyses according to DIN EN 8065.
See datasheet „Plate Heat Exchanger Requirements - Limit Values for Drinking Water Quality“.
