District Heating Network Boiler Hire Package
The Challenge
When the district heating network at a local MOD base failed, residents living on the campus were left without heating and hot water across multiple accommodation blocks. With comfort, safety, and continuity of service at risk, an urgent temporary boiler hire solution was required to restore essential heating provision as quickly as possible.
Following an initial investigation, the fault was identified as an underground pipework leak rather than a failure of the central boiler plant. As a result, six buildings located to the north of the site were isolated from the network and left without thermal supply. This complex site layout meant that a decentralised approach was needed, requiring individual temporary boiler systems to be installed at each affected building.
Celsius Hire was contacted to provide immediate technical support, site assessment, and rapid mobilisation of a reliable boiler hire package. Our engineering team attended site at short notice to carry out a full survey, assess load requirements, and design a compliant temporary heating solution tailored to the site’s operational needs. This proactive response enabled us to minimise disruption, safeguard resident welfare, and restore heating and hot water with minimal downtime.
If your site is facing an unexpected heating failure or requires emergency boiler hire support, our specialist team is ready to assess, design, and deploy a dependable temporary solution without delay.
The Solution
Within one hour of the initial call, Celsius Hire had an experienced engineer on site to carry out a detailed survey across all six affected buildings. This rapid response allowed our team to assess site conditions, identify suitable connection points within each plant room, and determine safe, compliant external locations for the temporary boilers and fuel storage tanks.
As each plant room had a different layout and operational configuration, confirming individual connection points was essential to ensure a seamless installation and minimise disruption to residents. Our engineers worked closely with site representatives to verify pipework compatibility, access routes, and safety clearances, enabling accurate planning before equipment mobilisation.
Based on the site survey and calculated heat loads, Celsius Hire designed a bespoke temporary boiler hire solution tailored to the demands of the district heating network. The package included six 600kW temporary boilers and one 300kW boiler, providing sufficient capacity to restore reliable heating and hot water across all affected buildings. Each unit was supplied with a dedicated 3,000-litre fuel tank to support continuous operation and reduce the need for frequent refuelling.
To ensure safe and efficient integration with the existing high-temperature, high-pressure district heating infrastructure, all boilers were connected using specialist flexible hoses fitted with 4” PN16 flange couplers. This specification was essential to accommodate system pressures and operating temperatures while maintaining performance, reliability, and compliance with industry standards.
Through detailed planning, rapid mobilisation, and technically robust equipment selection, Celsius Hire delivered a fully engineered temporary boiler solution designed to perform under demanding conditions. Organisations facing similar district heating failures or planned maintenance requirements can rely on our team to design and deploy tailored boiler hire packages that meet both operational and regulatory demands.
The Result
On the following day, Saturday, Celsius Hire mobilised and delivered the full temporary boiler hire package to site, including all seven boilers, dedicated fuel tanks, flexible hoses, and essential ancillary equipment. This rapid logistics response ensured that installation could begin immediately, without delay.
Working in line with the MOD base supervisor’s priority schedule, the Celsius Hire engineering team coordinated installation and commissioning activities to restore heating to the most critical buildings first. This structured, phased approach helped to protect resident welfare and minimise disruption across the site while works were completed.
Alongside our engineers, the client’s appointed mechanical contractor deployed a specialist team to support system integration, ensuring secure and compliant connections to the district heating network within each plant room. This collaborative working model enabled efficient problem-solving and maintained full compliance with operational and safety requirements.
Through coordinated planning, skilled installation, and rigorous commissioning procedures, all temporary boilers were fully fired and operational by Monday. Heating and hot water services were successfully restored across every affected building, bringing the site back to full functionality within a tightly controlled timeframe.
This project demonstrates Celsius Hire’s ability to deliver high-capacity emergency boiler hire solutions under demanding conditions, combining rapid response, technical expertise, and dependable equipment. For organisations requiring urgent district heating support or planned temporary boiler installations, our team provides proven, end-to-end delivery from initial call-out to full system commissioning.
