Intellihot Instantaneous Tankless Commercial Water Heaters

Intellihot logoCarotek is the exclusive Intellihot instantaneous gas-fired water heaters distributor in VA.  Carotek offers product sales, local inventory, as well as factory authorized service for Intellihot, the technology leader in this field.  Intellihot tankless water heaters are designed and built entirely in the U.S. 

The tankless water heaters operation is up to 40 percent more energy efficient compared to traditional heating methods. As a result, commercial properties can dramatically minimize the cost of water heating. When savings really matter, these heaters are the smart solution.  These units allow you to conserve space by eliminating the need for redundant heaters/boilers and reducing or eliminating the need for storage tanks.

As building technology keeps evolving, water heating systems have been stuck in the Dark Ages. Intellihot changes that: delivering endless hot water on demand while consuming less space and resources by every measure.

Intellihot Tankless Water Heater Products

iQ Series - Delivering the ultimate in on-demand water-heating capacity.

  • Versatile - Ideal for hotels, schools, hospitals, restaurants, laundromats and other commercial applications.
  • Economical - 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.
  • Robust - Commercial-grade, expandable 316L stainless steel heat exchanger with proven durability.

Intellihot has created a revolutionary heat exchanger after years of research, that is the best in the industry. At the heart of the heat engine is a single finned stainless coil that is designed to float freely. This unique feature allows for rapid thermal cycles by allowing the coil to expand or contract.

IQ series tankless commercial water heaters

Cold water enters the coil at the bottom and is carefully heated to the correct temperature before emerging at the top, ready for use. The modulating premix burner fires radially outwards to precisely match the load. By condensing the flue gas, we’re able to absorb 12% more heat than in other models. The condensate flows downwards in the same direction as the flue gas, thereby preventing any gas side fouling. Flue gases move downwards to the bottom casting while water flows in the opposite direction, collecting maximum heat along the way.

Using patented vibration and turbulent flow technology, the heat exchangers possess the unique ability of being “Self-descaling,” keeping lime scale in suspension and ensuring years of like new operation. These features and many others can be found in our line of Intelligent water heaters – only from Intellihot.

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 unit has enough internal intelligence to perform independently. In fact, if any one unit needs to be checked or serviced, the cascade will continue to function smoothly to ensure continuous hot water.

We offer six iQ Series models:

  • iQ3001, which delivers 3 million BTUs
  • iQ2001, which delivers 2 million BTUs
  • iQ1501, which delivers 1.5 million BTU,
  • iQ1001, which delivers 1 million BTUs
  • iQ751, which delivers 751,000 BTUs
  • iQ251, which delivers 251,000 BTUs
