only inconvenient, it is also completely unnecessary, for
a correctly functioning thermostatic valve will do all this
by itself: if the room temperature rises above the value
set on the sensor head, the thermostatic valve will close
automatically; when the temperature falls below the set
value it will open again.
Do not cover thermostatic valves
Do not cover the thermostatic valves with furniture,
drapes or similar objects. The room air must circulate
unhindered. Covered thermostat valves can be equipped
with remote sensors and thus still work.
Appropriate hot water temperature
The hot water should only be heated as much as is re-
quired for use. Any further heating will result in unnec-
essary energy consumption.
Energy-conscious use of water
Energy-conscious use of water can also reduce costs
considerably. e. g. showering instead of bathing: Where-
as approx. 150 liters of water are needed for a bathtub,
a shower equipped with modern, water-saving fittings
requires merely about a third of this volume. Besides: a
dripping tap wastes up to 2000 litres and a leaking cis-
tern up to 4000 litres of water in a year. On the other
hand, a new seal only costs a few pence.
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 en-
hance the convenience of the hot water generation
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. Circulation pumps
should only be operated, therefore, when there is actu-
ally a general requirement for hot water. Using timer
switches, with which most circulation pumps can be
equipped or retrofitted, individual timer programmes
can be set. Weather compensators often have ancillary
functions for controlling circulation pump timings. Ask
your specialist company.
Airing the rooms
During the heating period, open windows only for venti-
lation and not for temperature regulation. A brief, high-
volume ventilation is more effective and energy-saving
than leaving a tilting window open for a long period. We
recommend that the windows be opened fully for a
short period. When ventilating the room, close all ther-
mostatic valves in the room or specify the minimum
temperature at the room thermostat (if installed). In this
way, there will be adequate ventilation without unneces-
sary cooling and energy loss (e.g. as a result of the
heating switching on during the ventilation procedure).
