A New Meaning to "Smart Water"

Delivering the Ultimate in on-demand water heating capacity

Our iQSeries floor-standing units, iQ3001, iQ2001, iQ1501, iQ1001, and iQ751 deliver the ultimate in on-demand water-heating capacity. iQ3001 is Intellihot’s most powerful model and gives new meaning to “smart water.” It’s our highest capacity on-demand water heater yet, delivering 3 million BTUs with no storage tanks required. The iQ2001 delivers over 2 million BTU/hr, the iQ1001 delivers over 1 million BTU/hr and the iQ751 delivers over 751,000 BTU/hr each with no storage tanks. These high-input units are designed for very large volume commercial applications.


Looking for the most powerful solution possible?

With our iQ2001 and iQ3001, we have the two largest on demand solution in the industry. For situations where you need higher capacity, you also have the option to team together multiple iQ units. For example, you can cascade four iQ1501 units to create an over 6 million Btu/hr system, or four iQ1001 units to create an over 4 million Btu/hr system. Imagine what you can do with 160 GPM at 70°F rise, 24/7/365? The configuration possibilities are endless, and the performance is second to none.

The iQ Series models learn your building recirculation so they can automatically power on pumps and set the temperature to minimize cost without losing comfort. Slash capital cost up to 50%, reduce operational cost up to 40% (compared to traditional tank-type systems).

Prevent Costly Oversizing

Instead of sizing a water-heating system and then adding redundancy, you now have a far better option: Our iQ series incorporates built-in redundancy, completely eliminating the need for oversizing. For example, each iQ1001 unit includes four independent heat engines that operate as an integrated system. If any one of the four internal modules experiences a malfunction, the remaining three will continue to operate – providing 75% of the original capacity.
