Temporary Heating Support
for a Live Police Facility

Modern brick office building with blue entrance and autumn trees

Crawley Police Station required a temporary heating solution to maintain continuity of service within a live operational environment. Working alongside Capitol Engineering, TCS was tasked with integrating temporary plant into a complex existing LTHW system serving multiple zones, risers, and air handling units.

In a building operating 24/7, continuity of heating and hot water was essential — with minimal tolerance for disruption or instability.

The situation

The site operated a complex multi-boiler LTHW system supporting heating and hot water across the wider facility. The infrastructure included:

• Multiple boilers and circulation pumps
• Zoned heating circuits
• Air handling units (AHUs)
• Riser-fed distribution systems

Temporary plant needed to be installed quickly and integrated into the live system without impacting operational activity within the building.

The challenge

Several factors increased the complexity of the project:
• Integration into an existing multi-boiler heating system
• Working within a live police environment with continuous occupancy
• Limited internal and external space for plant positioning
• Safe external flue discharge requirements
• Maintaining stable system flow, pressure, and hydraulic balance across multiple circuits
• Coordinating installation without disrupting ongoing operations

Because of the interconnected nature of the system, any instability or failure would quickly become a site-wide issue — making careful interface planning critical.

The thinking

Rather than relying on a basic temporary setup, the project required a solution that could integrate cleanly into the building’s existing infrastructure while maintaining operational stability.

TCS deployed a modular packaged boiler system, positioned externally and connected into the site’s LTHW distribution network.

The installation included:

• Modular boiler units providing built-in redundancy appropriate for the nature of the building
• Integrated controls and remote monitoring capability
• Flexible braided hose connections to simplify integration and speed up installation
• Pre-fabricated spool pieces designed to interface efficiently with the existing headers

Internal connections were carefully integrated into the plantroom distribution system, linking into the site’s boilers, circulation pumps, risers, and AHU circuits in a controlled and structured manner.

The focus throughout was not simply installing temporary plant, but ensuring the entire system behaved as expected once operational.

The outcome

The temporary heating system was successfully integrated into the existing infrastructure and brought online without disruption to the live facility.

• Heating support was restored within a complex, multi-zone environment
• System pressure remained stable at normal operating parameters
• Plate heat exchanger separation ensured reliability and prevented pressure imbalance issues
• No evidence of mechanical failure, connection faults, or installation defects was identified during operation

The project demonstrates TCS’s ability to deliver technically robust temporary heating solutions within operationally sensitive environments where continuity, control, and reliability are critical.
