Intellihot iN501 Neuron Series Indoor Floor Mounted On-Demand Water Heater

Intellihot iN501 - i Series - Tankless Water Heating Systems

Intellihot iN501 Neuron Series Indoor Floor Mounted On-Demand Water Heater 

When space and cost are important deciding factors, you can count on our Neuron Series units for superior performance and reliability. Ideal for commercial applications, our tankless water heaters provide 94% thermal efficiency and are constructed for maximum durability – even in the most demanding commercial applications.


  • Compact Drop-In Replacement - Like the iN199, these units are over 8” slimmer than a typical tank and feature similarly located water in and out for easy hook-up without the need to re-pipe. Replace the typical tank units in a flash.

  • Built-In Redundancy - All Neuron models come with two separate heat engines, independently controlled thus eliminating additional expense and space for a redundant backup water heater.

  • Direct Cell-LTE Connectivity -  Remotely access and monitor our Neuron unit via LTE cell connectivity features. No need for your building’s Wi-Fi. 

  • Mobile App, telliCare - Use Intellihot’s mobile app and start monitoring your unit. Check water inlet/outlet temperatures, flow rates, flue gas temperatures, and the life of key parts, available on your mobile device of choice.

  • Low Gas Pressure Operation - The system operates on low gas pressure, down to 2.5” WC, without reductions of capacity.

  • Eliminate Mixing Valves & Lower Legionella Risks - With no storage tanks, there’s a lower risk for Legionella growth. By eliminating the need for a mixing valve, this feature also reduces their associated unreliability and costs.

  • Flexible - Floating Heat Exchanger Design - stress-relieving and thermal shock-resistant

  • Multi-Unit - Masterless cascading with common venting

  • 7” Color Touch Screen - access to usage data, troubleshooting, and parts wear.
