Masterless Cascading Ensures Zero Downtime

All of our commercial hybrid water heaters can be cascaded for increased capacity. And yet, each one operates autonomously. This means cascaded units do not require a master controller (the kind that causes a single-point failure).

With Intellihot’s patented design, each iQ Series unit has enough internal intelligence to perform independently. In fact, if anyone unit needs to be checked or serviced, the cascade will continue to function smoothly to ensure continuous hot water.



Ideal for hotels, schools, hospitals, restaurants, laundromats and other commercial applications.



Eliminates the need to oversize an installation with redundant equipment.


Better ROI

Lower capital and operating costs compared to boilers and tank-style water heaters.



Commercial-grade, expandable 316L stainless steel heat exchanger with proven durability.
