the extent that is necessary for use. Any further heating
results in unnecessary power consumption and hot
water temperatures of more than 60 °C also lead to
increased lime scale reduction.
Switching on comfort mode (only VUW):
Comfort mode immediately supplies you with hot water
at the required temperature, without you having to wait
for the water to heat up. For this, the hot water heat
exchanger is kept at a preselected temperature level. To
prevent energy loss, set the temperature selector not
higher than the required temperature. If you do not need
hot water for a long period, it is recommended to turn
off comfort mode to save energy further.
Energy-conscious use of water
Energy-conscious use of water can also reduce costs
considerably, e.g. taking showers instead of baths:
whereas about 150 litres of water are required for a
bath, a modern shower equipped with water saving
fittings only requires a third of this water quantity. By
the way: a dripping water tap wastes up to 2,000 litres
of water and a leaking toilet flush up to 4,000 litres of
water each year. On the other hand, a new seal only
costs a few cents.
Run circulation pumps only if needed
Circulation pumps facilitate the continuous circulation of
hot water through the piping system which means that
hot water is immediately available, also at more distant
draw-off points. These pumps undoubtedly enhance the
convenience of the hot water production process. But
they also need power. And circulating hot water that is
not used cools off when passing through pipes and then
needs to be reheated. Therefore, circulation pumps are
to be operated only when hot water is actually needed
for the household. Individual timer programmes can be
defined using switching clocks, which are already
installed or can be retrofitted in most circulation pumps.
Weather compensators often have ancillary functions for
controlling circulation pump timings. Consult your
heating engineer. Another option is to turn on the
circulation only for concrete needs for a specific period
of time by using a button or switch installed near a
frequently used draw-off point. A corresponding button
can be connected to the Vaillant ecoTEC plus boiler
electronics.
