HIGHER EFFICIENCIES Of course, installing boilers on a


prefabricated rig system is not a new concept. Retrofitting high-efficiency condensing boilers on a rig unit brings numerous advantages, achieving the required improved heating efficiency in a high-quality solution.


How? By sharing the load across multiple boilers, the condensing boilers can operate at part load where they are at their most efficient. The arrangement also makes full use of their modulating feature, improving the overall efficiency of the heating system.


As a result, the building’s load demand can be matched more accurately. The building’s occupants benefit from the increased reliability of the heating service, while the reduced energy waste means lower energy bills. And as the factory-finished unit arrives pre-tested from one supplier, quality control is improved.


GO BESPOKE But a standard rig unit might not


be perfectly suited to every project, especially if the plant room has size or shape limitations. Forward-thinking manufacturers have addressed this with a new service that offers the opportunity to have a rig system designed and built bespoke to meet the exact requirements of the project and the site.


The first advantage of a bespoke prefabricated rig is that it minimises the hassle factor associated with refurbishment.


TIGHT SCHEDULES A major benefit of prefabrication is


the ability to customise. The bespoke rig can be designed to overcome any space issue – down to the positioning of the low loss headers. This means that it can be installed in a fraction of the time, making it the perfect solution for facilities managers working to tight or fixed refurbishment schedules.


Equally, where there is a requirement to complete a series of projects within a short timeframe, a bespoke- designed prefabricated rig provides a

rapid, high-quality solution to high- efficiency heating. Schools are a case in point as most refurbishment work is scheduled to be carried out in the six-week summer holiday period.


“THE BESPOKE RIG CAN BE DESIGNED TO


OVERCOME ANY SPACE ISSUE.”


CUSTOMISED TO MEET


SPECIFIC REQUIREMENTS When it comes to specification, a prefabricated solution like the bespoke rig meets the immediate needs for increased reliability and efficiency of heating – and more.


The bespoke rig can accommodate most requirements. So if water quality is an issue, it can be designed to achieve hydraulic separation via the rig and a plate heat exchanger. It can also include controls specific to the project. This can be useful in museums and art galleries where a weather compensation control can help meet the need for a close- controlled environment.


ASSISTS FM CYCLE Importantly, a prefabricated solution


like the bespoke rig is designed to meet both the present and future needs of the building.


This stems from the inbuilt redundancy of the multiple boiler arrangement, which ensures more reliable, secure heating provision for the comfort of the occupants. Even if one boiler is removed, the heating provision will continue uninterrupted.


ZERO DISRUPTION The improved ease of installation


not only reduces time and labour but keeps disruption or upheaval to the absolute minimum.


This is particularly relevant to the private rented sector as landlords are often required by terms in leases to compensate any tenants subjected to disruption. Many landlords may be considering heating refurbishments, as from 1st April 2018 it will be unlawful under the Energy Act 2011 to let properties with an Energy Performance Certificate rating of F and G. Here again, replacing any inefficient boilers with multiple condensing boilers on a bespoke- designed rig provides a hassle-free retrofit solution – helping landlords raise the energy performance of their properties in compliance with the new minimum energy efficiency standards.


This configuration also makes servicing easier, supporting the future maintenance requirements of the building. At the same time, the design reduces the individual use of each boiler. As a result, their individual lifecycle is extended, bringing further long-term savings. The bespoke rig also improves asset management, assisting the facilities management cycle.


Prefabricated bespoke rig systems bring numerous benefits. Preassembled, pre-tested and built to the client’s exact specification, the bespoke rig unit is wheeled into the plant room for rapid, easy connection to the existing system.


From the initial trouble-free installation to the reliable, high- efficiency heating it achieves and the future FM benefits it offers, this quality heating solution exemplifies the power of prefab.
