Gas Boiler Maintenance in Tallinn
Gas boiler maintenance in Tallinn and Harjumaa. We check boiler operation, burner, heat exchanger, pressure, controls, flue, ventilation and overall operating stability.
Regular gas boiler maintenance
Gas boiler maintenance helps reduce the risk of faults, detect problems early and keep heating and hot water operation stable.
During maintenance, it is important to check not only the boiler itself, but also its operating conditions: system pressure, controls, combustion, flue gas discharge, ventilation and air supply. If the boiler shows error codes or works unstably, separate diagnostics may be required.
What gas boiler maintenance includes
- visual inspection of the gas boiler and connections;
- checking the burner and combustion chamber;
- assessment of heat exchanger condition;
- checking heating system pressure;
- checking ignition, flame and controls;
- checking the pump, sensors and operating modes;
- assessment of the flue, ventilation and air supply;
- recommendations for repair, adjustment or part replacement.
When gas boiler maintenance is needed
- the boiler has not been serviced for a long time;

Frequently asked questions
Short answers about gas boiler maintenance.
How often should a gas boiler be maintained?
Regular maintenance is recommended, especially before the heating season. The exact interval depends on the boiler model and manufacturer recommendations.
Can maintenance remove a boiler error code?
Sometimes maintenance may resolve the issue, but if the error returns, diagnostics are needed to find the actual cause.
