🔧 Vaillant Boiler Repairs in St John’s Wood
Domestic & Commercial Heating Experts in NW8
At RARE Plumbing London, we understand that heating failures are never convenient — especially when your property relies on a Vaillant system for comfort and control. Whether you own a family home near Hamilton Terrace or manage a commercial building off St John’s Wood Road, our engineers deliver fast, professional Vaillant boiler repairs in St John’s Wood.
We work discreetly, cleanly, and with expert knowledge of both domestic and commercial Vaillant boilers, including the ecoTEC and ecoTEC plus ranges, and larger commercial wall-hung and floor-standing models.
🛠️ Common Vaillant Faults We Resolve
Whether your Vaillant boiler is showing a fault code or struggling with poor circulation or intermittent heating, we’re equipped to fix it quickly and correctly:
F22 – Low Water Pressure
We’ll repressurise the system and test the expansion vessel to stop pressure loss from recurring.
F28 / F29 – Ignition Issues
We test the ignition electrodes, gas valve, and flue system for flame loss or lighting failure.
F75 – Pump or Sensor Fault
Often caused by circulation issues. We test, flush, and replace components as needed to restore full performance.
F62 – PCB or Gas Valve Fault
A tricky fault in commercial and residential models — we’ll isolate the issue and replace with manufacturer-approved parts.
F76 / F83 – Overheating or Flow Discrepancies
In larger systems, these are often signs of blockages or failing pumps. We diagnose and balance the system properly.
💬 Unsure what your Vaillant error code means? Our engineers will explain it clearly and provide an honest plan of action — no jargon.
