Decade '2020

2022

Riello celebrates 100 years since its foundation and continues to innovate with smart and sustainable solutions.


2021

Riello launches a new line of residential boilers designed to be 20% hydrogen powered and to be integrated with IoT systems for remote control of comfort and consumption.

Riello has also launched an ambitious project to develop a range of burners and blown boilers (condensing boilers combined with burners), specifically developed to operate efficiently and safely with green hydrogen.
It has completed tests at the Combustion Research Centre in Angiari (Verona) on a series of condensing blown boiler units fuelled 100% by hydrogen, achieving excellent performance in terms of eliminating carbon oxides in the flue gas (CO-CO2) and very high energy efficiency.


2020

Riello becomes part of Carrier Global Corporation, which becomes an independent, listed company following its successful spin-off from United Technologies.
With the TAU N range, Riello is one of the few companies on the market that can boast high water content condensing boilers up to 3 MW. The 3-pass stainless steel flue gas exchanger, produced in the centre of excellence in Volpago del Montello, is the heart of the technology that guarantees highly efficient combustion and low emissions. The range is offered in combination with an RX series pre-mixed gas burner produced and developed in the Legnago factory.

TAU N
Represents one of the highest expressions of Riello's great expertise in the commercial segment.

Ultra Low NOx technology
The combustion gas recirculation (FGR) technology is based on the partial recirculation of combustion fumes inside the burner and allows very low values of polluting emissions to be obtained. Riello is the world leader in Ultra Low NOx burners with FGR technology from 195kW to 19.5MW.
