■

The largest financial savings will be achieved if the
power generated by the fuel cell module is con-
sumed on site. Whenever possible, do not switch on
large energy consumers (e.g. oven, hairdryer, vac-
uum cleaner, washing machine, tumble dryer) simul-
taneously but after each other.

■

Spread the drawing of heat (e.g. DHW consumption)
as evenly as possible over the day. This results in
longer fuel cell module runtimes for power genera-
tion.

■

The energy manager optimises the fuel cell module
runtimes subject to power and heat consumption
within the building. Activate the energy manager to
optimise utilisation of power generated on site: See
page 18.
