Hallo zusammen! Ich versuche herauszufinden, welche Einstellungen für meinen Heizkörper am besten sind, und bin etwas verwirrt. Hier ist die Situation:
Wir haben diese Standardheizkörper mit nummerierten Einstellungen. Die Einstellung auf 3 scheint am logischsten zu sein, aber aus irgendeinem Grund gibt es ständig Geräusche und es fühlt sich an, als würde sich der Heizkörper immer wieder aufheizen. Außerdem mache ich mir Sorgen, dass ich bis zum Ende des Winters eine riesige Energierechnung bekomme, also versuche ich, vorsichtig zu sein.
Ich lüfte den Raum regelmäßig, schalte dabei aber nicht den Heizkörper aus – ich habe das Gefühl, dass es besser ist, ihn auf einer konstanten Einstellung zu belassen. Alles über 3 (z. B. 4) fühlt sich viel zu heiß an, aber ist 3 tatsächlich effizient? Sollte ich einfach dabei bleiben, oder wäre es besser, den Wert noch weiter herunterzudrehen oder bis zum roten Punkt anzuheben?

To the noises: Radiators regularly make them but they sometimes need to be aired out (depending on the type of radiator).
To the reheating: The thing you open is not there to heat permanently but to achieve a certain temperature. If that temperature is achieved it will stop until it needs to heat again, at least thats how my radiators work.
I can’t give you a certain „do x“, because I am no expert and just a regular dude, but at least I can add this info. The numbers meaning varies from radiator to radiator, I had appartments where 2 was perfect 22°C and I had appartments where 3.5-4 was about 22°C.
Sounds like air trapped in the system. Usually, it’s best to vent your radiators once a year before the heating period. Most probably you’ll need a special key to open the air vent (get it at the hardware store). You can Google the correct way to do it. You’ll also have to look if the water pressure in the system has dropped too much after venting. If that’s the case, contact your landlord, so he can call his contact for maintenance.

You have air inside. You have to open the small valve and let the air out until water will come out. Then no more noises and heat will be constant and uniform. About heating level it depends on so many factors… as an example, I have a very small living room and I keep the radiator always off; when I’m cold I just put it on 5 and the room is warm just after 10 minutes. Just use it as you feel comfortable 🤷♂️
“ and it feels like the radiator keeps reheating over and over” it’s exactly what the thermostat supposed to do.
Basic rules – keep your house minimum at 18-20 degrees (it’s between 2-3) and ventilate it at least once a day. The rest depends on your liking. Don’t worry about utility bill too much, it’s gonna be way more expensive to cure diseases caused by low temperature, just make yourself comfortable.
Those Radiators actually do measure the temperature, and adjust themselves to keep the room warm. So leaving it at 3 seems the best options, if you dont feel too cold at home.
Ventilating the flat is important. Best is to do the infamous „Stoßlüften“. You basically open EVERY window in your flat completely for around 5 min. If it feels like too cold, id recommend to buy a hygrometer, a digital one. Set it aside in a room with less ventilation, and keep it around 50%. If its not much more than that, you dont need to open the windows too often.
Constant noise from the radiator isn’t normal. Maybe there‘s air in the system? You should check that out.
How high you need to set the radiator to avoid mold depends on a lot of factors, including the insulation of your home. The best way to avoid mold is to get a hygrometer and try to keep the relative humidity below 60% by venting your rooms periodically and making sure it‘s warm enough. Set the temperature to a level that feels comfortable to you, observe the hygrometer and air out the apartment once you hit 60% or above. If you struggle to keep it below 60%, turn up the heating.
Easiest solution: get hygrometers for each room (they are pretty cheap) and follow [this guide](https://www.verbraucherzentrale.de/sites/default/files/2019-05/energy-saving-tips-english-VZ-NRW.pdf) plus keeping the humidity below 60%.
The numbers on the radiator tell you to what temperature you’re trying to heat the room. The 3 setting means 20°C room temperature. Does that sound like the temperature you want?
If the radiator is making noises, it probably means you need to bleed it (=let out the air). In general the recommendation is to turn off the radiator for Stoßlüften.
If you want to save money, and you don’t use the room during certain hours, the recommendation is to turn the radiator down to 2 to save energy and reduce costs.
In the end, it doesn’t just depend on the radiator though how much money you’ll have to pay because a well-insulated home will need less energy to heat up and maintain the heat.
