Modulating Technology
Modulation allows Brute™150-850 volume water
heaters to automatically adjust how much fuel is
used to match demand, from 20% to 100% of full
power. Brute™150-850 volume water heater models
will operate at 100% only when demand is at its
highest, and they will modulate down as demand decreases. The result
is energy savings of up to 30% compared to standard “on-off” units.
Easy on the Environment
The Brute
™
150-850 volume water heaters also
feature low NOx emissions. NOx, Nitrogen Oxide,
is a group of gases that form when fuel is burned
at high temperatures, and it can react with other
volatile compounds (VOC) to form air pollution
known as smog. Brute™150-850 volume water
heater models produce very low levels of nitrogen
oxides, less than 10 ppm, so they provide
efficient heat while minimizing the impact on
the environment.
Integrated Touch Screen
Control System
The Integrated Touch Screen Control System,
standar
d on all Brute™150-850 models, monitors
all aspects of boiler operation and includes several
features that can improve the performance and
efficiency of the entire heating system. It also
allows for easier integration of cascade systems
into building automation networks.
