5.4 Hot-water ECO function
Combi-boilers and boilers with a separate water heater usually
have a heat-retention function. This means that the hot water
is kept at a specific minimum temperature.
If you require no hot water for a longer period, it is unnecessary
and a waste of energy. Celcia 20 has been set in such a way
that if you opt for the pre-programmed temperature ECO-
TEMP, the hot-water ECO function is active. The reaction to
this differs per boiler:
• Combi-boiler with flow switch: the system is not kept hot;
when you open the hot water
• Combi-boiler with temperature sensor: the system is not
kept hot; when you open the hot-water valve, you get hot
water as usual in most situations (depending on the cooling
down speed of the boiler). In some cases this may take a
bit longer.
• Central heating boiler with external hot-water storage
heater: the water heater is not kept hot; when you open the
valve you only get the hot water still present in the water
heater.
NB: if the boiler is emptied, it takes a long time before
warm water becomes available again.
Therefore, for boilers, we also advise switching off
the warm water ECO-function.
You can switch the warm water ECO-function on or off by
following the steps below:
1 Set the rotary knob on MENU.

gramme and close the lid.
Fig. 12 Activation and deactivation of the hot-water ECO function
Tip: if, for instance, you want to heat the boiler once at
5 o'clock at night, without the boiler going into operation for
central heating, set TEMP-1 at the same value as ECO-TEMP
and programme in P1 e.g. from 5:00 - 6:00 hours TEMP-1.
