Laars
Rheos
Modulating Boiler/Water Heater
The
Rheos smart boiler / water heater is a breakthrough
in commercial heating system design. Now, for the
first time, engineers and heating contractors can
choose a single high-efficiency, low-cost system for
commercial installations requiring up to 2.4 million
BTU/hour. Plus, the Rheos features the highest
density and smallest footprint available, so it
takes up far less floor space. In fact, it's so
compact, it can fit through a standard 3'-0"
doorway.
