Heating and ventilation


The room temperature in a residential block should be approx. +19–21C. When the room temperature is lowered by one degree, the heating costs are reduced by approx. five percent.

The room temperature can be controlled with the thermostat

A thermostat needs time and space to function. Do not hang heavy curtains and do not place heat-generating equipment in front of the thermostat.

Thermostats must not be turned by force; the possible adjustment is approx. 2-3 degrees. The radiators can sometimes be cold or only warm in the top section, this shows that the thermostat is working.
Even if the radiator feels cold, the room’s temperature can be suitable and healthy.

Water and drains

Leaking or otherwise defective water fittings increase the water consumption and can cause damage due to damp. If the toilet leaks continuously, it uses more than 50 m3 water during one year; this costs thousands of euros extra.

Do not put anything down the drain if it does not dissolve in water!

Do not place sanitary towels, nappies, tampons, cotton wool or dental floss in the toilet.

Food leftovers or coffee grounds must not be swilled down the sink, because they may block the drain. The solid materials collect in the drain’s U-bends and block them. If the drain does not run, stop running water immediately. Do not use WC fragrances either. If a WC fragrance blocks the drain, the tenant pays the costs incurred for unblocking the drain.

Consider the environment and save costs

  • immediately inform the service company about leaking taps and toilets
  • do not let water run unnecessarily – water is expensive
  • a two-minute shower uses 24 litres of water and a 10-minute shower 120 litres
  • remember that hot water is almost twice as expensive as cold
  • wash cloths and dishes with full machine (if possible, use programmes that save electricity and water)
  • do not rinse the dishes under running water
  • keep the bubble nozzle clean – what is this?
  • make sure that existing installation of washing machines and connections have been done in a way the service company accepts. If there is no connection prepared in the accommodation, then such cannot be installed there.

Clean the drainpipe’s U-bend and floor drains regularly!

As a tenant, you must clean the U-bend and the floor drains in the bathrooms, which also have U-bends, yourself. At every drain point, there is a U-bend to stop the smell from the sewer system coming into the room. If the bathroom has not been used for a long time, the water can evaporate from the U-bend, and let out smells.

Cleaning the U-bend

Loosen the covering plug by hand. Remove the dirt and replace the plug.

Cleaning the floor drain

In the floor drain, it is above all hair that collects and therefore it must be cleaned regularly! You can lift the floor grate e.g. with a screwdriver. Hair and other rubbish are easily removed with the help of a small plastic bag. Finish cleaning using a washing-up brush. You can also use washing-up liquid. Last of all, rinse thoroughly and replace the cover firmly.


Do not connect any new parts to the water and drain system without the service company’s permission. Do not leave machines running unsupervised. Always turn off the washing machine’s taps after use.


The ventilation keeps the air in the accommodation clean. Mechanical extract ventilation sucks air out of those parts of the accommodation where the ventilation need is greatest (kitchen, bathroom, wardrobe room). Replacement air streams into the accommodation through the fresh air vents, which must not be allowed to become blocked.

Clean the extract air vents at least twice a year.

You can test how well the extract air vents are working with a piece of paper.

Cleaning the extract air vent

  1. Turn the outermost ring
  2. Pull out (NOTE! The location of the internal part must not be altered, it has been set for the right quantity of air)
  3. Wash the vent with washing-up liquid and dry it

Cleaning the cooker hood

Wash the cooker hood’s fat filter 4–6 times a year, with hot water and washing-up liquid.

Inform the manager/serviceman about:

  • any part of the water and drain system that is leaking or has broken
  • the drain running slow, making a strange noise, smell of drains in the flat
  • water disappearing from the U-bend time and again
  • the water pressure, if it is too low or too high
  • the hot water temperature, if it is continually low (under + 50C)
  • a radiator leaking or if its valve is broken
  • murmuring, surging or whistling water is heard from the radiator
  • it being constantly too hot or too cold in the flat or a particular room
