**) The water flow is stated
at 85 °C heating water
temperature and 35 °C
service water
temperature gradient
(10 °C HWS input
temperature, 45 °C
HWS output
temperature). If a boiler
with output different
from 26,5 kW is used
for the heater, then the
water flow will change
as follows(while
observing the above
input conditions):
0

200

The above times for water heating and its flow are valid in case that a Grundfos pump is connected to the
heating system and its revolutions switch is in position 3(which corresponds to
∼
720 l/h.). If the pump works
with lower revolutions (smaller flow quantity) the time of heating the service water will be prolonged..

IMPORTANT WARNINGS!
Set the thermostat of the heater to max. 60 °C temperature (note: The regulations in the Czech Republic do
not allow do distribute water of temperatures higher than 60°C).
Once a week set the thermostat of the heater to 65 °C temperature in order to avoid the formation of
legionella (bacillary bacteria originating in water. They die between 60 and 65 °C temperature within several
minutes and at 70 °C temperature they die within several seconds.).
