In all TYS housing locations, heating is controlled by house automation that regulates the temperature of the water circulating in the radiator network according to the outside temperature.

Bathrooms often have a separate heating system, which is why the bathroom radiator can feel warmer than the other radiators in the apartment. The bathroom radiators and the possible underfloor heating are always on in many locations, regardless of the season, to make the damp spaces dry more quickly.


If you feel that your apartment is too cold:

  • Make sure the radiator thermostat is turned to the open position. When the thermostat is turned to maximum, it should heat the room air to approx. +21 degrees.
  • Make sure the thermostat is not covered by thick curtains or furniture. It would be good to place the furniture at least 20 cm away from the thermostats, so that warm air can spread freely into the apartment.
  • Please note that, for example, when the outside temperature is approx. +10°C, warm water circulating in the radiators is at about +31°C. Then the radiator may feel cool to the hand, even though it is constantly heating the room air. In addition, when working correctly, the lower part of the radiator is often cooler than the top part. So, there is no reason to worry if the radiator is not evenly warm.

If, despite these actions, you feel that your apartment is cold, use a thermometer to measure whether the temperature is clearly below the recommended levels (+20–22°C) often or for long periods of time. The temperature should be measured at a height of 1.1 metres and at least 0.6 metres from the wall. You can pick up a thermometer from the TYS housing office during office hours.

If the temperature you measured is below +20°C and you have considered all the other above-mentioned points, submit a fault report. Include the temperature you measured in the fault report.


Do not attempt to bleed the radiators yourself

Do not, under any circumstances, try to bleed the radiators yourself. Water damage caused by bleeding the radiator is the tenant’s responsibility. If you suspect that there might be air in your radiator, or you have some other reason to think that the radiator is not working properly, submit a fault report via the tenant pages.


If you feel that your apartment is too hot:

  • Check that the radiator thermostats are in the closed position
  • Check that the replacement air vents are open and that the exhaust air vents are working normally
  • Close the curtains during the day and air out the apartment in the evening or at night

If you fail to cool the apartment with normal methods, you can get devices that circulate or cool the air in your apartment, such as a fan or a portable cooling device.

Please note, however, that it is forbidden to install any fixed structures (such as an air source heat pump) in the apartment. The tenant is responsible for any damage caused to the property, structures, and materials (such as windows) and for the incurred repair costs.


Air-cooling devices include a risk of water damage

Please also note that there is also a risk of water damage in air-cooling devices. Many devices have a separate container for condensed water, and you must monitor this container. A cooling device equipped with a water container must never be left on unattended; this means that you cannot leave the house or go to bed with the device running.

In the worst case, water leaking from the device can cause water damage in the apartment and you will be responsible for paying these damages. Carefully read the operating instructions of the device you intend to use.
