Heating and ventilation

The right temperature and efficient ventilation are important so that your housing will feel comfortable.

AF Bostäder’s heating policy

By keeping the environment in focus, AF Bostäder shall be able to provide homes and properties with a good indoor climate. Our aim is to provide at least 20°C during the day and 18 - 20°C at night, between the hours of 22.00 - 06.00.

Our policy has been created in order to optimize both comfort and economy, since a large part of AF Bostäder’s costs, and hence your rent, are due to heating costs.

Your heating is controlled by thermostatic valves

The heating in your apartment comes from hot water that circulates through the radiators. A thermostatic valve on each radiator ensures that the correct amount of hot water is circulated in relation to the temperature in the room.

You can control the temperature in the room by turning the thermostatic valve and thereby increasing or decreasing the water circulating in the radiator. However, the heating system is limited to a maximum of about 20 degrees, according to our heating policy. For the thermostatic valve to function well, there need to be a free circulation around it. Therefore, you should not place sofas or hang heavy curtains close the thermostatic valve or in front of the radiators.

The radiators are cold

When the weather changes and it gets cooler outside, you can sometimes feel that it is a little colder indoors. If the radiators are cold it is usually because they do not begin to heat until the indoor temperature is below 20 degrees, regardless of the outdoor temperature and the temperature of the elements. The beauty of this is that you do not use more energy than necessary.

Air properly

Air efficiently and for only a short period, or shut off the thermostatic valve when you air. The cold air from a window that is open will influence the thermostatic valve. It will allow more hot water to circulate in the radiator without increasing the indoor temperature and a large amount of energy will be wasted.


Ventilation is necessary for a healthy indoor environment. The volume of air, etc. is regulated by law and is checked at regular intervals. The ventilation system in a home can be designed in different ways, but there is often an air extractor in the form of a cooker hood, fan or ventilation unit in kitchens and bathrooms. Fresh air is often introduced through vents in outer walls or under windows.

During the cold part of the year, draughts may be felt from the fresh air vents, but the vents are located to provide the best possible ventilation in the home. Do not block or cover vents, otherwise air will enter through other openings and upset the indoor climate and the fine adjustments that have been made to ensure correct air exchange.

If your housing feels cold

If a room gets too cold, a fault may have occurred. Check if the indoor temperature is less than 20 degrees. To do this, place a thermometer at about 1 m height in the middle of the apartment. Radiators shall be set to maximum and windows closed. Your caretaker can help you. You should continue measuring for about 24 hours. If the temperature is considerably less than 20 degrees, you should make a fault report. It is important that you make a fault report so that we can rectify the problem, do not increase the temperature by operating electrical heaters or similar, these use more energy and more expensive energy, than the normal heating system.

If your housing feels hot

When it gets warmer outside, the temperature in the room is affected by the outside temperature. Some tips to keep the room cool can be to obtain sun protection for windows, airing short and efficient, and keep the exhaust unit free from dirt. NOTE! If you buy equipment that is not included in the contract, you must pay for it yourself.

What can you do?

  • Do not block your radiators with large pieces of furniture or long curtains – when you do, the heat ‘bounces’ back to the radiator, which signals that it is warm enough and the radiator will go cold. This also applies to the thermostat, so if you have long curtains, make sure they do not hang in front of the knob and capture the heat.
  • Keep an eye on the sealing strips around your windows and doors. If you feel a draught, the strips may need to be replaced. Contact your building manager.
  • Close your curtains/blinds at night, which will help keep out the cold.
  • Do not close ventilators or vents. The building was constructed to allow circulation and if you close ventilators or vents, circulation stops, which affects both air quality and temperature.Air rooms quickly and thoroughly instead of having the window cracked all day long. Turn off the radiator and open the window wide for a short time. If you have more than one window, by all means open them so that you get a cross-draught. After a few minutes, close the windows and turn the radiator on again.

Acute heating shut-off

Sometimes the heating is shut-off due to a serious fault at our district heating supplier, Kraftringen. This means that the radiators do not work and there is no hot water supply. Your cold water supply works as normal and you can heat up water on the stove. For more information on the shut-off, visit Kraftringen’s website: www.kraftringen.se/kundservice/Avbrottsinformation/

If the heating suddenly is off

A short heating interruption does not normally cause much inconvenience. If you keep the windows closed it takes quite a long time before the temperature in your housing falls. If the heating interruption is during the winter and you think it is starting to get cold in your housing, you can keep warm by using a blanket or putting on extra clothes until the heating is back on. Candlelight can increase the temperature. Another temperature-raising tip is to gather several friends in the same room. Four people generate the same heat as a small radiator.
