What our Experts Think  

• Strong whole-home indoor hot water performance — The SH22 Series delivers 6.8 GPM (≈140,000 BTU), making it capable of supplying multiple fixtures at once, including up to several bathrooms in small-to-medium homes, townhouses, condos, and cabins.
• SmartHome control for modern living — Built-in WiFi connectivity allows full app-based control plus Alexa and Google Assistant integration, enabling remote temperature adjustment, scheduling, and system monitoring from anywhere.
• Space-saving indoor installation — Compact wall-mounted design eliminates the need for a storage tank while freeing up utility space, with indoor venting options for flexible installation in mechanical rooms or closets.
• Efficient on-demand heating system — Tankless operation heats water only when needed, helping reduce standby energy loss compared to traditional tank water heaters while maintaining continuous hot water delivery.
• Energy-smart features built in — Includes Eco Mode, scheduling, and smart diagnostics that help optimize gas usage and improve efficiency depending on household demand patterns.
• Designed for practical household use — Rated for typical residential applications including single-family homes, apartments, and light commercial setups where consistent hot water demand is required.
• Things to consider before buying — Professional installation is required for gas and venting safety, and performance depends on correct sizing (flow rate + temperature rise). Like most tankless systems, it works best with stable water pressure and may require periodic descaling in hard water areas.

Maintenance Tips  

• Install indoors in a well-ventilated space with proper venting to safely exhaust combustion gases.
• Keep vent pipes, air intake, and exhaust pathways clear to prevent error codes and efficiency loss.
• Flush the system every 6–12 months (more often in hard water areas) to prevent scale buildup and maintain 6.8 GPM performance.
• Clean the inlet water filter every 3–6 months to ensure stable ignition and consistent flow.
• Inspect gas line, water connections, and electrical wiring regularly for leaks, corrosion, or looseness.
• Maintain proper natural gas pressure and water pressure (typically 50–80 PSI) for safe, stable operation.
• Use the SmartHome WiFi app to monitor temperature, diagnostics, and error alerts for early maintenance.
• Ensure indoor installation meets clearance requirements to avoid overheating and combustion issues.
• Protect from freezing by keeping indoor temperatures above 0°C (32°F) or draining if shut down.
• Schedule annual inspection of burner and heat exchanger for soot, scale, or wear.
• Always turn off gas and power before servicing or maintenance for safety.
