Energy-saving tips
Appropriate hot water temperature
The warm water should only be heated up to the extent
that is necessary for use. Any further heating results in
unnecessary power consumption and hot water temper-
atures of more than 60 ºC also lead to increased lime
scale production.
Run circulation pumps only if needed
Circulation pumps do indeed increase convenience when
it comes to hot water production. 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 oper-
ated only when hot water is actually needed for the
household. Individual timer programs can be set using
autotimers which are already installed or can be retrofit-
ted in most circulation pumps. Weather compensators
often have ancillary functions for controlling circulation
pump timings. Consult your heating specialist company.
