Description

RHeco unit heaters have the highest efficiency and the lowest NOx and CO2 emissions available today.

The RHeco is a fully condensing gas fired unit heater. With its thermal fficiency up to 109% and low NOx and CO emission rates < 25 ppm, the RHeco exceeds European norms, including seasonal efficiency and NOx emissions requirements coming into force in 2021.

In conventional unit heaters, some of the heat is lost in the flue gases. In the Reznor RHeco, these flue gases are led through a second heat exchanger which cools them down to a temperature below the dew point. This way, water vapour will condense and release its latent heat into the air flow.

The design of this gas fired unit heater combines high thermal efficiency, quality components and ease of maintenance for enhanced life expectancy and reduced life cycle costs.

The new modulating premix burner with the combustion circuit under negative pressure ensure its safety, high efficiency and low emissions.
