The Perfect Drop-In Solution
The iN401, iN501, and iN199 are the first drop-in ready tank replacement units that provide all the features and benefits that Intellihot is known for in a smaller and more compact footprint.

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.
Economical
Eliminates the need to oversize an installation with redundant equipment.
Better ROI
