Ignition electrodes

Boiler repair at home in Karasu-1
Home visitDiagnostics with repairWarranty on labor
Boiler repair in Karasu-1: the technician checks ignition, pressure and the heat exchanger in the canal-side massiv and agrees work after diagnosis.
Weak DHW in the east often comes from scale in the secondary exchanger — hard water in the canal massiv.
For boilers in Karasu-1 we plan coaxial access: say whether the kitchen or loggia faces the water courtyard.

How to arrange a visit
- Karasu-1 address, wall-hung or floor-standing, and access to the gas cock and flue.
- Share any display fault code and the symptom: no heating, no DHW, or falling pressure.
- If you smell gas, shut the cock, open a window and do not switch electrics until the gas service is safe; the boiler visit follows that.
How the visit works
Expansion vessel
We check pre-charge and the membrane when pressure jumps on heat and dumps through the relief.
Circuit pump
We listen to and test circulation if radiators stay cold and the boiler does not trip on overheat.

Topic 1 / 3
Gas boiler heat exchanger cleaning
If radiators stay lukewarm, the boiler is slow to heat, or it short-cycles — scale in the heat exchanger is a common cause. It cuts heat transfer, raises gas consumption, and can overheat the unit.
On diagnostics the technician flushes the primary and secondary exchangers, checks temperature sensors and the return filter. We agree the scope and price before cleaning starts.
