Boiler Repair in Petroșani

About this service

Most boiler faults don't appear suddenly: they result from lack of maintenance, untreated hard water, and pressure left outside the normal range for months. Limescale in the hot water exchanger gradually reduces flow and forces the burner to work harder, leading to overheating and repeated lockouts. An annual service — legally required for gas boilers — costs a fraction of a new heat exchanger and significantly extends the appliance's life. A conscientious technician doesn't simply replace the suspect part but first checks system pressure, the state of the expansion vessel, and circulation, because an identical symptom can have completely different causes.

What to check before hiring a boiler repair

Book the annual service at the end of summer, not in peak season when waiting times increase
Check the pressure gauge monthly; normal cold pressure is between 1 and 1.5 bar
Ask for proof of qualification before allowing work on a gas boiler
If the boiler is under warranty, use a manufacturer-approved firm so you don't lose it
Don't repeatedly top up pressure without finding the leak — the problem gets worse
Fit a magnetic filter and, in hard water areas, a softener — both greatly extend exchanger life

Frequently Asked Questions

What do the error codes mean?

Each manufacturer has its own coding, but common patterns exist: ignition faults indicate no gas, a dirty electrode, or a failed fan; low pressure errors signal a leak in the system or a failed expansion vessel; overheating codes point to poor circulation, often from limescale or a seized pump.

Why is my boiler losing pressure?

The most common causes are a leak on the heating circuit — at a radiator, valve, or joint — and an expansion vessel with a ruptured diaphragm that no longer absorbs water expansion. The second situation is more common than people think and is checked simply, by measuring the pressure at the vessel's valve.

Do I need a qualified technician?

Yes, work on gas boilers must be carried out by qualified personnel. Qualification matters for safety, for maintaining the appliance warranty, and for situations where documentation is needed. Ask for proof of qualification and check the firm is approved by the boiler manufacturer if it's still under warranty.

How often should the boiler be serviced?

Annually, and for gas boilers this is a legal obligation rather than a recommendation. The service covers cleaning the burner and heat exchanger, checking for leaks, flue gas analysis, checking expansion vessel pressure, and adjusting parameters. It's best done at the end of summer, before the cold season.

I have heating but no hot water. Why?

That's the classic symptom of a limescaled hot water exchanger or a seized three-way valve. On boilers with plate exchangers, limescale from hard water gradually reduces heat transfer until the water no longer heats sufficiently. The solution is descaling or, in advanced cases, replacing the exchanger.

Is it worth repairing an old boiler or should I replace it?

The practical rule is that a repair shouldn't exceed 40–50% of the price of a new boiler. On appliances older than 12–15 years, with recurring faults or parts that are hard to source, replacement becomes more economical, particularly as current condensing models consume significantly less.
