    Not just hot water. Smart water.

    Our water heaters recognize water-use patterns and deliver hot water as soon as you turn on the faucet. Our units run themselves, with no master controller to fail and no need to shut the whole system down for service.

    No wait, no waste.

    Traditional water heaters keep large tanks of water hot, while water in the pipes cools down between uses. With Intellihot, no tank means no wasted water, space, energy or time.

Meet our new brand mascot, Telli


Telli, a robot, is our new brand mascot. Telli embodies the DNA of our company – innovative, smart and hi-tech, yet playful and accessible. Our new logo also speaks to our founders’ expertise in robotics and mechatronics. Our futuristic water heaters use robotic technology to self-learn usage patterns and to communicate with each other.

Water heating & Delivery Reinvented

Founded in 2009, after a traditional water heater broke down and flooded our founder, Sridhar Deivasigamani’s basement, Intellihot today designs, manufactures and assembles tankless water heaters for residential, commercial and industrial applications—the first to do so entirely in the United States. Quality and innovation are at the heart of all our products, which were developed following years of extensive research. We continue to be recognized for our innovative design and have several patents.
