Gas appliances and installations

A gas appliance is an installation or system of structures used to produce, process, transmit, store, use, or fill gas, including a natural, liquefied, biogas or industrial gas tank, pipeline, terminal, filling, or gas station.

A gas installation is a permanently installed operational system of gas pipelines and associated buildings. It also includes safety, control, instrumentation, and regulating equipment installed on the gas installation.

Market surveillance of gas appliances


Gas appliances on the market must not endanger persons' health and safety, provided that they are correctly manufactured and installed, maintained regularly following the manufacturer's instructions, and used for their intended purpose.

The manufacturer or the person who places the gas appliances on the market must ensure that the gas appliances placed on the market are safe and comply with the Product Conformity Act's requirements and subordinate acts.

The Consumer Protection and Technical Regulatory Authority is competent to suspend the distribution and use of potentially dangerous gas appliances placed on the market for the time necessary to verify their conformity. Suppose the expert assessment shows that the gas appliance does not comply with the requirements. In that case, the Consumer Protection and Technical Regulatory Authority has the right to order the withdrawal of the gas appliance from the market.

Gasworks is considered the design, manufacture, construction, installation, dismantling, adjustment, testing, and repair of a gas appliance or gas installation, including filling a gas cavity and gas storage.


Gas work is permitted to an undertaking registered in the register of economic activities as carrying out gas work, provided that and to the extent that a person responsible for the gas work is present and competent.

The gas installation owner must ensure that a registered company carries out the gas work and that the maintenance of the gas installation is carried out at the frequency specified by the manufacturer.

The flue pipe of the gas heater must be cleaned at least once a year. The flue stack may only be cleaned by a qualified chimney sweep, who will issue the owner with a cleaning report stating the work carried out, the defects found, and, if necessary, proposals for remedial action.

You may use the gas appliance for the period of use specified by the manufacturer. If the manufacturer has not specified a service life for the gas appliance, the specified service life shall be 15 years.


A Category "A" gas installation with a working pressure not exceeding 0,1 bar (inclusive), which is more than 15 years old and is located in a building used for public purposes or in common areas of a block of flats, may be used if an audit has been carried out which concludes that the installation is in a technically sound condition and safe for use. You must order a further audit every four years. The owner of the gas appliance is obliged to keep a record of the technical inspection.

Inspecta Estonia OÜ and Tehnoaudit OÜ carry out gas appliance audits in Estonia.

When connecting a gas appliance using liquefied petroleum gas to a cylinder, it is crucial to check whether the appliance is intended for use only outdoors or in adequately ventilated areas. As a general rule, LPG cylinders should not be installed near building exits, shafts, stairwells, or rooms with a floor surface below ground level.

When positioning the cylinder, ensure that:

  • the LPG cylinder is installed so that it does not exceed 40 °C and is in an upright position.
  • in residential premises (including apartment blocks) and premises for public use, one may store no more than 25 kg of liquefied petroleum gas (LPG) in any one room.
  • The pressure regulator's outlet pressure to reduce the pressure of the cylinder gas in the accommodation and catering space shall not be adjustable (30 mbar), and the pressure regulator shall be connected directly to the cylinder valve.
  • the hose used for the LPG transfer shall be suitable for the LPG, the pressure to which the hose is expected to be exposed during use, and shall be attached utilizing a clamp or special fitting.
