Boiler replacement · London residential projects
A boiler replacement that protects the whole system.
Vaillant and Viessmann replacements carried out with the preparation, protection and commissioning needed for dependable long-term performance — not treated as a simple appliance swap.
System preparation
Cleaning or powerflushing is specified where appropriate, rather than connecting a new appliance to unresolved contamination.
Protection & water quality
Magnetic protection, inhibitor and water-quality checks help protect the new boiler and support manufacturer requirements.
Controls & commissioning
Controls are reviewed, operation is checked and the complete installation is commissioned before handover.
