2.5 CONNECTION OF INDIRECT HEATER TO HOT WATER HEATING
SYSTEM
a) Water heating by electric energy
After the heater is connected to electric network, the heating element starts heating water. The element is
turned on and off by a thermostat. After reaching the temperature set, the thermostat switches off the
electric circuit and thus discontinues water heating. The control light signals if the element is in operation
(light is on) or if it is off (the light goes out). In case of longer operation without using the heated volume,
the thermostat has to be set to position 5°C to 8°C (set the "snowflake" symbol on the thermostat selector)
to avoid its freezing, or electricity supply to the heater has to be switched off. In combined versions, the
stop valve on the inlet to the exchanger has to be closed, which prevents heating water in the hot water
heating system.
