Commercial Boiler Upgrade at Milton Park, Abingdon

We recently completed a full commercial boiler upgrade at LTI Metaltech in Milton Park, Abingdon, replacing outdated Ideal Concord CX60 floor-standing boilers with a modern Vaillant ecoTEC Plus cascade system.

Milton Park is one of the largest business parks in Oxfordshire, with high demand for reliable commercial heating systems across industrial and manufacturing facilities. This project required a complete redesign of the plant room to improve efficiency, reliability and long-term serviceability.

The Existing System

The existing plant room at LTI Metaltech consisted of two Ideal Concord CX60 floor standing boilers. While these systems had provided reliable service, they were becoming inefficient and increasingly difficult to maintain due to age and parts availability.

The layout of the plant room also limited accessibility for servicing and did not allow for efficient modern control or system separation. This made it an ideal candidate for a full upgrade to a modern commercial heating solution.

The Upgrade

We upgraded the system to a modern Vaillant ecoTEC Plus commercial boiler cascade, installed on a bespoke Unistrut framework. This allowed for improved access, better load distribution and a more serviceable layout.

The system was designed using a reverse return pipework configuration to ensure balanced flow across both boilers, maximising efficiency and performance. A plate heat exchanger was installed to separate the system water, protecting the new boilers and improving long-term reliability.

We also installed a new pressurisation unit and upgraded pipework throughout the plant room, along with a new flue system routed through the roof. The result is a highly efficient and robust commercial heating system suitable for a demanding industrial environment.

System Specification

The upgraded system included:

• Vaillant ecoTEC Plus commercial boilers installed in cascade
• Reverse return pipework configuration for balanced flow
• Plate heat exchanger for system separation and protection
• Bespoke Unistrut framework for improved installation and access
• Pressurisation unit to maintain system pressure
• New flue system routed through the roof
• Fully upgraded and insulated copper pipework throughout

This specification ensures maximum efficiency, improved reliability and easier long-term maintenance.

The Result

This commercial boiler upgrade at Milton Park has delivered a significantly more efficient and reliable heating system for LTI Metaltech.

By upgrading to a cascade system with proper hydraulic separation and balanced pipework, the site now benefits from improved performance, redundancy and long-term serviceability. The new plant room layout also allows for easier maintenance, reducing downtime and future operational risk.
