berliners, when does your heating period go from-until?

The may-to-sept window is actually pretty standard for central systems in Berlin. Most buildings around here run from October through April or May, with some variation based on the weather and how cheap the landlord is.

The equal share thing is frustrating, especially if you're in a lower floor or south-facing unit. You're basically paying for the heat that rises to the floors above you. Check your Nebenkostenabrechnung for Heizkostenverteiler readings - some buildings have individual meters even if it doesn't feel that way.

If you're worried about costs, look into whether your building has Fernwärme or a gas boiler. Fernwärme tends to have a high Grundpreis but lower per-kWh costs, so it can be brutal if you're not using much heat. Your Hausverwaltung should have that breakdown in the annual statement.

you're getting solid advice already, just wanna add that the heizperiode itself isn't really regulated by law here - it's more of a convention based on the heizverordnung in your mietvertrag. some contracts literally say "heating from october to april" but others just say "when outside temp drops below X" which leaves it up to the hausverwaltung. yours shutting off sept 11 is actually early, a lot of systems in prenzlauer berg run till end of sept if the weather's meh

the bigger thing nobody's flagged is that your equal share model might be illegal if the building has more than two units. the heizkostenverordnung says at least 50% must be consumption-based if it's technically possible. if your radiators have those little white evaporative tubes on the side, you're probably already being billed per unit even if it feels like a flat split - check your nebenkostenabrechnung for "verbrauchsabhängige kosten" line items

another angle - check if your building has a "freie heizung" clause in the mietvertrag. some contracts say the landlord can decide when to turn it on/off based on outdoor temp, usually 15°C or below for three consecutive days. yours running from may to sept without a break sounds like they're just running it on a fixed schedule instead of actually monitoring the weather, which wastes heat on warm days in april or october

the real money saver might be asking about hydraulischer abgleich. most altbauten in berlin never had one done, so the heat distribution is totally unbalanced. you end up with some flats boiling while others freeze, and the system runs harder than it needs to. if your radiators make gurgling sounds or one room is way hotter than another, that's a sign. costs about 1000-2000€ for a whole building but can cut heating costs by 15-20% - worth bringing up at the next eigentümerversammlung if you're in a we or with the hausverwaltung if it's a rental

Worth noting that Berlin street names have official umlaut and ß rules that trip people up, so a sign showing "Strasse" versus "Straße" is not actually a spelling error, just an older transcription. Same with "ue" versus "ü" (e.g. "Kantstrasse" vs "Kantstraße"), both are considered valid renderings and you'll see the ß version on the blue Schilder and the ss version on older plaques or in databases that predate Unicode. If the difference you're seeing is between those two forms, there's nothing to fix and both are technically correct.

if the signs u mean are the old enamel ones on the house facades those are often protected as Baudenkmal so nobody's allowed to correct them even if the spelling is outdated. the binding version is whatever is in the Berliner Strassenverzeichnis plus the entry in the Liegenschaftskataster, so if u tell me the street i can point u to the right Bezirksamt Mitte or Charlottenburg-Wilmersdorf page. tbh the merged district thing is real but the facade signs are a separate story, theyre basically museum pieces at this point

honestly thats super common in Charlottenburg, the district offices were merged from older Bezirke and nobody ever fixed all the Schilder. if its a real street you can check the official strassenverzeichnis on berlin.de, that list is what the Burgeramt actually goes by. which street is it? some of the Kaiserdamm / Kantstrasse signs are notorious for this.
