Intellihot iQ251 Gen II – i Series – Tankless Water Heating Systems
With 96% thermal efficiency and flexible design and circuit options, iQ251 and iQ251D models are the best-in-class wall-hung, ASME-compliant, tankless water heaters. These wall-hung iQ models are constructed for maximum durability and the most demanding commercial and industrial applications. The iQ251D is the only gas-fired, deionized on-demand water heater on the market. Both iQ251 and iQ251D deliver 251,000 BTU/hr
Features:
-
Wi-Fi & Cellular Connectivity – Real-time monitoring of your Gen II unit is available through the unit’s 3.5\\” touch-screen – and accessible remotely via a mobile app. Each unit can be easily connected to your building’s Wi-Fi router or Intellihot’s internet hub.
-
Masterless Cascading- Eliminate single-point failure with our patented Masterless Cascading technology. If one cascaded unit is offline for servicing, all other units regroup and continue to operate. Cascade up to 2,510,000 BTu/hour (10 units) for larger applications.
-
Eliminate Mixing Valves & Lower Legionella Risks- With no storage tanks, there’s a lower risk for Legionella growth. By eliminating the need for mixing valves, these features also reduce their associated unreliability and costs.
-
Full Modulation – Smart units deliver maximum BTU/hr input when needed and zero BTU/hr the rest of the time
-
Gas-Fired – By using natural gas our system lower operating costs and improve ROI vs. electric water heaters. 73KW of heating capacity available with low-pressure drop; capable of 9.6 GPM at 50F temperature rise.
-
Common Venting Capabilities – The iQ251 and iQ251D units transform common venting into smart-common venting.
-
ASME-HLW Compliant – Suitable for applications managed by engineers, specifiers, and contractors.
