There are approximately 800,000 households in Slovakia with at least one chimney. Two new buildings. It is necessary to check and, if necessary, clean not only classic chimneys with a fireplace or heavy tile stove connected, but also chimneys to which condensing boilers or other central heating boilers are connected.

The basic task of the chimneys is to “remove” the combustion products from the appliance outside the building. During combustion, soot is formed. The soot in the “chimney travel” process, whether horizontal or vertical, cools and settles on the chimney walls. Over time, deposits on the chimney walls increase! Experts associated in the Chamber of Chimney Sweepers say that the risk of fire increases (especially for fireplaces and ovens) when the inner wall of the chimney has a three millimeter coating of soot.

Therefore, the chimneys must always be cleaned after the heating season in order to prevent soot burning out. When they burn, a temperature in excess of a thousand degrees Celsius is created, which can destroy the chimney with consequent damage to the bush or the house. It is therefore clear from the description that the chimney should be paid attention and it does not matter whether it is a chimney of a new building or a chimney of an older house. Here, particular attention should be paid to the necessary care.

LEGISLATIVE CLEANING ADJUSTMENTS

Regular cleaning and inspection of chimneys is regulated by Act No. 314/2011 Coll. – On fire protection. The periods of cleaning and inspection of individual types of chimney according to the type of appliance connected to the chimney are specified in more detail in the Decree of the Ministry of Interior of the Slovak Republic No. 401/2007 Coll. in § 20.

HOW FOR NEW BUILDINGS?

The Fire Protection Act lays down obligations for both legal and natural persons (ie all owners of family houses) that the owner of the property must carry out a check and ensure a professional examination before starting the operation of a heating system where the fuel is burned directly and the combustion products are removed. of chimneys by persons holding licenses before the appliance is permanently connected to the chimney body.

In layman’s terms, this means that if you build a family house before you start operating your fireplace, gas or other boiler permanently, an inspection technician – a chimney sweep – must come to check and test the chimney. In this inspection, it is also necessary to mention the obligation to check the source of combustion products, ie inspection of boilers, fireplaces or tile stoves…

The appliance (flue gas source) must be cleaned within the time limits specified by the manufacturer in the appliance documentation. If this deadline is not specified in the documentation or is missing, the appliance must be cleaned within the periods of cleaning and inspection of the chimney.

DOCUMENTS ABOUT INSPECTION AND CLEANING

The chimney or flue gas cleaning and inspection shall be certified by the worker who performed the chimney or flue gas cleaning and inspection, or shall be entered in the chimney or flue gas cleaning and inspection log with the date of the inspection together with the name and surname of the person and the cleaning was done. Deficiencies found during cleaning and inspection, which cannot be remedied immediately during cleaning and inspection of the chimney or flue, shall be described in detail in the confirmation of cleaning and inspection – it is for the owner to remedy the deficiencies as soon as possible. The law recognizes that cleaning can also be carried out by the owner himself! However, this can become a problem in claiming damages with insurance companies !!!

The law and the decree further specify how to deal with chimney documents. Confirmation of cleaning and inspection of the chimney and flue or confirmation that the chimney has been inspected is issued for inspection purposes and is presented to the municipality or the authority carrying out state fire supervision (eg inspection by firefighters, but also in case of an insured event). This means that the owner should keep all chimney or appliance care documents so that they can be retrieved and available even after any disaster affecting his family home.

HOW MUCH YOU PAY

The price for inspection and cleaning of the chimney ranges from 10 € to 30 € per object, vent. It depends on the diameter of the vent, the length of the flue, the type of fuel and the type of appliance. Do not forget to think about traffic. You will pay approx. 50 € / 1 vent and 1 appliance approx. 65 € for the inspection report for the house inspection.

HOW OFTEN IS NEEDED TO CHECK AND CLEAN THE CHIMNEYS?

If appliances with a total heat output of up to 50 kW are connected to the chimney body, once every:

  • four months if solid or liquid fuel appliances are connected to the chimney,
  • six months if gaseous fuel appliances are connected to the chimney and if the chimney is not lined,
  • twelve months if gas appliances are connected to the chimney and the chimney is fitted with an insert.
