TNG Services Ltd replaced an ageing Vaillant ecoTEC plus 635 system boiler with a new-generation ecoTEC plus 635 at a property in Sunnyfield, Mill Hill. After approximately 20 years of dependable service, ongoing age-related problems meant it was time for an upgrade rather than continuing to spend money on repairs.

A Vaillant boiler that had served the property well

The existing ecoTEC plus 635 had provided many years of dependable service. However, continuing age-related problems made further repair spending less attractive, and replacement was chosen to improve heating efficiency and reliability.

Replacing the ecoTEC plus 635 with a new-generation model

We replaced the ageing appliance with a new-generation Vaillant ecoTEC plus 635. The homeowner now has a modern system boiler ready to meet the property’s heating and hot-water needs.

Rerouting the gas pipe near the flue

The boiler replacement also provided an opportunity to improve the existing pipework layout. The gas pipe had been positioned too close to the flue, so we rerouted it as part of the installation to improve separation.

A modern replacement for heating and hot water

This Sunnyfield project retained the Vaillant ecoTEC plus 635 model choice while moving the property to the new generation of the appliance. The replacement was chosen to improve efficiency and reliability after many years of service from the original boiler.
