Ionization
We clean and set the electrode if a north-western boiler clicks, lights and goes out at once.

Home visitDiagnostics with repairWarranty on labor
Boiler repair in Karakamysh-2: in the second quarter we check ionization, the heat exchanger and the condensate trap, and agree work after diagnosis.
A boiler that lights and dies more often fails on the ionization electrode and burner soot, not “empty” gas at once.
We enter Karakamysh-2 through a multi-storey quarter yard: say if the coaxial faces the stair or the second-quarter courtyard.

How to arrange a visit
- Karakamysh-2, wall-hung or floor-standing, access to the cock and flue.
- Fault code, no heat, no DHW, falling pressure, or a blocked trap — describe the symptom.
- In Karakamysh-2 a gas smell in the second-quarter yard: shut the section riser cock, open the stair leaf and do not start the boiler until gas confirms it is safe.
How the visit works
Heat exchanger
We assess scale and overheat when section radiators stay lukewarm and the boiler short-cycles without a lockout.
Condensate trap
We flush the drain if a condensing unit blocks start after a long idle in the second quarter.

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.
