With a small adjustment on the heating you can save money while you sleep.
How it works – and for whom nighttime reduction is worthwhile.
In times of high energy prices, it is worth checking where you can save money on heating.
However, you don't have to forego living comfort.
Programmable radiator thermostats can be a solution that automatically lowers the room temperature.
Homeowners can also activate night time reduction on their heating system.
What is night setback?
During the night setback, the heating works with lower flow temperatures.
This reduces the heat output of the heating system and the temperatures in the house gradually fall, as the
Heiz.de
portal explains
.
After the nightly reduction phase, the heating system starts up again in time so that the comfortable temperature is reached again in the morning.
The night reduction can be set on the central heating system.

Setting the night setback on the heating – tips
Homeowners activate the night setback on the central heating system.
Where exactly the setting is made varies depending on the heating model.
As a rule, night setback can be activated via the “Time control” or “Time program” menu item.
When setting the night setback, the most important thing is to pay attention to the correct time and temperature:
Since the room temperature does not fall immediately, you can start the night setback while you are using it in the evening, for example from 10 p.m.
Choose to start the heating phase about one to two hours before you get up so that you are nice and warm again at this time.
The lowering temperature should be at least 17 to 18 degrees Celsius to prevent mold from forming in the living spaces.

Since every building reacts differently to temperature changes, different heating times can also make sense - the only way to do this is to try it out.
If you are still unsure about setting the night setback, you should seek help from a heating specialist.
When is night reduction worthwhile?
According to the
consumer advice center
, night-time reduction in a single-family home can save between five and 12 percent of heating energy.
However, this is only a rough guideline, because whether nighttime reduction is really worthwhile depends on various factors.
These include, for example:
the construction of the building,
the insulation standard as well
Type of heating and heating surfaces.
“The lowering phases make sense in buildings with little or no insulation and a medium-heavy construction.
This applies at
least if the heating is based on low-temperature or condensing technology and transfers heat to the rooms via radiators,” says
Heiz.de.
According to experts, night-time reduction is hardly worthwhile in solidly constructed buildings or well-insulated houses.
The same applies to living rooms with underfloor heating, as they react very slowly to temperature changes.
You can only find out whether night-time reduction is ultimately worthwhile in your house by determining the energy consumption and comparing these values with those from times before night-time reduction.
