So to avoid freezing this September, here's a quick introduction to your central heating rights according to the Deutsche Mieterbund (DMB). "If the room temperature sinks below 16C, the landlord must turn the heating on immediately." This means, in the event of a cold snap, landlords are sometimes required to turn the heating on in September or possibly even earlier. If the minimum temperature in the flat does not reach around 20C in the winter, according to the Deutsche Mieterbund, the landlord is obligated to fix the problem as this means the flat does not meet living standards. Similar laws apply if the hot water supply does not reach a minimum temperature of around 40-50C in the kitchen and bathrooms of a rented property.
