Gas valve
We check ramp pressure and coils if there is spark and the flame will not hold in the second belt.
Boiler repair at home in Karasu-2
Home visitDiagnostics with repairWarranty on labor
Boiler repair in Karasu-2: in the neighbouring canal-side massiv we check the gas valve, diverter and fault board, and agree work after diagnosis.
No DHW with hot radiators more often means the diverter and secondary exchanger, not an “empty” boiler at once.
We enter Karasu-2 from the drive between massivs: say if the coaxial faces the belt yard or the section end.

How to arrange a visit
- Karasu-2, wall-hung or floor-standing, access to the cock and flue.
- Fault code, no heat, no DHW, or jumping pressure.
- In Karasu-2 a gas smell on the canal belt: shut the section cock, open a window to the drive between massivs and leave the board until gas service clears it; the boiler visit follows.
How the visit works
Diverter and DHW
We inspect the spindle and secondary circuit when radiators heat and the section kitchen tap runs cold.
Board and faults
We read module history and sensors, without swapping a board “from a phone code”.

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.
