To ensure the DVGW Directive is fulfilled, an instantaneous heating
water heater or second heat generator should be installed, so that
DHW temperatures reach > 60 °C. Equipping the heat pump with an
instantaneous heating water heater fulfils this requirement.

7.13 Hydraulic connection of the cylinder loading system (for heat pump cascade with
Vitocal 200-A)
Cylinder with external heat exchanger (cylinder loading system) and heating lance
During the loading process (no draw-off), cold water from the cylin-
der is extracted from the lower section by means of the cylinder
loading pump. The water is heated in the heat exchanger and resup-
plied to the cylinder via the heating lance mounted in the flange.
The generously sized outlet apertures in the heating lance result in
low flow velocities, which in turn provide clear temperature stratifica-
tion inside the cylinder.
DHW booster heating is possible if an additional immersion heater is
installed (on site).
