In addition to the maintenance and repair of gas boilers and gas water heaters, our technicians can install carbon monoxide detectors. The detector can be ordered beforehand or you can choose it on site. A carbon monoxide detector must be installed into all residential rooms which contain a gas appliance connected to a chimney, for example, a boiler or water heater.
The Estonian Rescue Board recommends installing a detector on the wall of rooms which contain also other combustion-related appliances, for example, wood furnace, fireplace or stove.
We provide the service of detector’s installation only together with the maintenance service of boilers or water heaters, i.e., the installation of carbon monoxide detector cannot be ordered separately.

Safe use of gas
Gas needs oxygen
Natural gas as a fuel is very convenient and clean and its complete combustion emits only water vapour and minor amounts of carbon dioxide. However, all maintenance and safety requirements must be adhered to during operation.
The gas appliance must be protected from dust and it must be connected to a clean flue gas exhaust with suitable dimensions. The room containing a gas appliance must have sufficient air exchange which ensures the complete combustion of natural gas.
The combustion of one cubic meter of gas requires about 10 cubic meters of air. Access of fresh air must be ensured in small rooms, especially bathrooms, through air grille or opening under the door.
Common causes of gas accidents:
- Unserviced appliances, old pipes and negligence.
- Unauthorised reconstruction of ventilation pipes and flue gas exhaust or diverting the gas appliance’s flue gas to the wrong pipe.
- Clogged flue gas pipes.
- Damaged or corroded pipes and connections.
- Materials unsuitable for gas have been used in the piping.
- Small and unaired room with insufficient air exchange for the gas appliance.
- Old gas appliance.
Keep in mind:
- The gas flame must be blue, not yellow (also applies to stoves).
- If the ceiling becomes yellow or brownish, then there are problems with exhaust chimney.
- In case of suspicions you should always order an expert inspection. Gas works can be performed only by companies or persons who have the appropriate registration in the register of economic activities.
- A carbon monoxide detector must be installed into residential rooms which contain a gas appliance attached to a chimney.

Gas leak
Fragrances have been added to gas used in households so that people would sense gas leaks. Thus, a specific gas smell spreads in case of gas leaks. Leaks in underground pipes are detected with special gas measuring instruments.
In case of a gas leak:
- If possible, close the gas supply.
- Ventilate the rooms by opening the windows and doors.
- Do not use open flame or electricity in the room and, if possible, turn off the electricity in the gas leak area.
- Leave the dangerous area.
- In case of danger call the emergency 112 and the gas emergency phone 13 404.
Inspection and replacement of gas appliances
If you are planning to replace the gas stove, water heater, heating appliance or other gas-based appliance in your household with a newer one, then our client service can certainly help you with their knowledge and experience. The safety of gas appliances is the responsibility of their owner or possessor. In order to ensure safety, it must be kept in mind that the important requirement stipulated to gas appliances by the Product Conformity Act foresee regular technical maintenance of gas appliances. The recommended maintenance intervals have been given in the service manual of the gas appliance. Likewise, the pipes need to be checked and if the gas installation is older than 15 years and is located inside a public building or in the public rooms of an apartment building, then the inspection must be performed every four years. Unserviced gas appliances that are not in good working order must be repaired or replaced. If the appliance is indeed operational, then the inspection should be ordered from an accredited institution (e.g. OÜ Inspecta Estonia, OÜ Tehnoaudit), who shall certify the safety of the devices and extend their service life. However, experience has shown that old gas appliances, especially gas water heaters, are mostly obsolete, their operation is dangerous and they still need replacement.
When you are buying new appliances, then you should keep in mind that since 1996 all gas appliances manufactured in Europe must conform with the requirements of harmonised standards and have CE-marking.
Gas boilers, water heaters and gas stoves and replacement works can be ordered from companies who have the license for gas works.
