Our combi boiler services
- Annual combi boiler service: Burner and combustion chamber cleaning, heat exchanger check, flue gas and fan check, expansion vessel pressure adjustment and testing of the safety systems.
- Combi boiler repair: Ignition, pump, fan, three-way valve, sensor and electronic board faults.
- Radiator flushing: Machine cleaning of the sediment and sludge built up in the system, so radiators that weren't heating work efficiently again.
- Pressure and pipework checks: Leak detection, bleed valve and valve checks.
Why does boiler pressure drop?
Ideally, boiler pressure should be between 1.2 and 1.5 bar when cold. If the pressure keeps dropping, there may be a small leak in the pipework or radiators, too little air in the expansion vessel or a fault in the pressure relief valve. You can raise the pressure temporarily with the filling tap under the boiler, but if it keeps happening, the problem won't be solved until the source is found.
If there's no hot water from the boiler
If the radiators heat up but no hot water comes from the tap, the problem is usually caused by the three-way valve, flow sensor or plate heat exchanger. Limescale in the plate heat exchanger is common throughout Aydın, where hard water is widespread.
When should a combi boiler be serviced?
A combi boiler should be serviced once a year, before the heating season starts (September–October). Regular servicing lowers fuel consumption, reduces the risk of breakdowns and keeps the boiler running safely.
Common combi boiler faults
- Boiler not working at all or not igniting
- No hot water, or only lukewarm water

- Radiators not heating up, bottom staying cold
- Fault code on the display (F, E, A codes)
- Noise from the boiler, frequent switching on and off
- Water leaks and dripping
- Fan, pump, heat exchanger and board faults

Frequently asked questions
How long does a combi boiler service take?
A standard combi boiler service takes about 1 hour. If radiator flushing is included, it can take 2–3 hours depending on the number of radiators.
What should the boiler pressure be?
When the boiler is cold, the pressure should be between 1.2 and 1.5 bar. It is normal for it to rise to around 2 bar while running; if it goes above 3 bar, call a technician.
My boiler is showing an error code. What should I do?
You can reset the boiler once. If the error comes back, send us the code and the boiler's brand; our technician will arrive prepared.
Is radiator flushing necessary?
If your radiators are hot at the top and cold at the bottom, or are slow to heat up, sediment has built up in the system. Radiator flushing speeds up heating and saves fuel.
