Intellihot IQ251 & 251D (De-ionized) Tankless Hot Water
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.
• Wi-Fi and 3G/4G 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 to 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 & Legionella – With no storage tanks there’s no risk for Legionella growth. By eliminating the need for mixing valves, this feature also eliminates 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 systems 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.
