Maintaining comfort and controlling energy costs in K-12 schools is a high-stakes responsibility. Unexpected downtimes, rising utility bills, and service interruptions simply aren’t options.
The Riello Array 2.0, a pre-packaged boiler plant, meets these challenges with unparalleled redundancy, efficiency, and long-term savings for educational facilities.
The Riello Array 2.0 uses a 40:1 turndown ratio to operate more efficiently by adjusting its heat output to match real-time demand. This means the system can scale down to just 2.5% of its full capacity, avoiding the wasteful cycling that leads to unnecessary wear and higher energy use.
This precise control results in smoother operation, longer equipment life, and lower energy bills. And when combined with multiple units, the overall system can achieve up to
Traditional boilers require complete shutdowns during maintenance, resulting in disruptions to heating systems. For schools, this often means costly weekend or holiday work, uncomfortable classrooms, and potential equipment damage.
The Riello Array 2.0 changes the game. Its modular design means you can service or repair individual modules without taking the whole system offline. This keeps the heat flowing, so no one has to worry about unexpected downtime or cold buildings. Each module operates on its own, giving you built-in redundancy and ensuring your facility stays warm even when maintenance is underway.
Not only does this reduce downtime, but it also cuts down on emergency repairs and long-term costs. With the Riello Array 2.0 you’re ensuring comfort and consistency for your students, staff, and anyone depending on that heat. It’s a solution that lets you focus on what matters, without worrying about whether your heating system will let you down when you need it most.
Cutting operational costs is crucial, and Riello Array 2.0 does it brilliantly with its advanced cascading technology. This system optimizes how the modules work together, ensuring that each module operates only when needed, maximizing fuel efficiency. Achieving up to 99% efficiency, its a significant improvement over conventional boilers.
For facilities like schools operating on tight budgets, this means the system keeps running efficiently, even when minor issues arise. The Array 2.0’s sophisticated design results in major energy savings, cutting utility bills while still providing peak performance.
The dual helical coil heat exchanger in the Riello Array 2.0 is engineered for durability. Its free-floating coil design reduces internal stress and minimizes scaling, which means fewer repairs and a longer lifespan for the boiler.
Its unique flow-independent design also eliminates the need for a minimum flow rate, allowing each module to adjust independently to changing conditions. This ensures consistent performance across varying loads, reduces the risk of thermal shock, and makes the boiler more adaptable and easier to manage across different applications.
New regulatory requirements are coming for Davidson County and Gallatin, Tennessee. Beginning in the first quarter of 2025, all condensing boilers will need to use UL-rated flue pipes in compliance with UL-1738. The Riello Array 2.0 fully meets these standards, making it a future-proof solution for schools and other facilities.
By choosing the Riello Array 2.0, you’ll avoid costly retrofits and last-minute changes that non-compliant systems will face. Designed with future regulations in mind, it ensures your facility stays compliant and ready for the next generation of HVAC standards.
