Riello is an Italian company that has been manufacturing burners and heating systems for 100 years. The company was founded in Italy in 1922, and it has since grown to become a global leader in the heating and combustion industry. Riello’s products are used in a variety of applications, including residential, commercial, and industrial heating systems, as well as in power plants and other industrial processes.

Throughout its history, Riello has focused on innovation and quality. It has consistently invested in research and development to improve its products and stays at the forefront of the industry. The company has a wide range of burners, boilers, and other heating products that are designed to be energy-efficient and environmentally friendly.

Riello commercial boilers are designed to provide heating and hot water in commercial, industrial, and institutional settings such as schools, hospitals, hotels, and office buildings.

Riello commercial boilers are available in a range of sizes and styles to meet the specific needs of different types of buildings. They offer gas, oil-fired, electric boilers, and models that can run on multiple fuel types. Many of their boilers are designed for high efficiency and low emissions, helping to reduce energy costs and environmental impact.

Explore some of Riello's commercial boilers below.

Riello RTC Commercial Boilers

Introducing the RTC Boilers – the perfect solution for heating systems and hot water production. These boilers are designed for maximum efficiency high water content, and three effective flue gas passes. Its stainless steel construction, titanium stabilization, and heat stratification principle allow for operation with no limits on return water temperature, maximizing flue gas condensation.

Riello RTC Models 3000 – 6000 have a vertical structure with overlapping cladding for easy handling and installation in a heating plant, while models 8000 – 10000 have a “square” structure with a single cladding to maximize water content and efficiency. All models have a fully opening front door and flue gas chamber for easy inspection, maintenance, and cleaning.

Choose the RTC for reliable, efficient heating and hot water production. In addition to low polluting emissions, reduced average body temperature, and quick, steady state times, the RTC offers multiple system solutions thanks to its compatibility with SOLO, PICCOLO, and MASSIMO adjustment panels. These boilers comply with ASME directives and can be combined with gas burners and mixed gas-light oil burners (when an anti-condensate pump is installed).

Riello Array Boilers

The Riello Array is a revolutionary pre-packaged boiler plant that offers unparalleled efficiency and reliability. Each Array boiler is equipped with multiple heat exchanger modules, which provide high turndown and multiple boiler redundancy within a single packaged unit. This means that a single Array boiler offers the uptime reliability that is typically only found in larger boiler plants or multi-boiler systems.

One of the key features of the Riello Array is its flexibility in installation. It has single-point connections for hydronic, electrical, fuel, and venting, and its small footprint means it can fit through a standard doorway. Additionally, it has a range of venting options, including sidewall, through the roof, and direct vent, with a maximum exhaust vent length of 100 equivalent feet. The Array boiler is also compatible with a variety of venting materials, including CPVC, polypropylene, and AL29-4C stainless steel.

In conclusion, the Riello Array Boiler System is a top choice for business owners looking for a reliable, efficient, and cost-effective solution for their heating needs. With its innovative design and advanced technology, the Riello Array Boiler System is able to deliver superior performance and long-lasting durability, making it the perfect choice for any commercial facility. So if you want a boiler system that you can rely on to provide consistent, high-quality heat, choose the Riello Array Boiler System.

Array
