Install-Ready By Design
The NTI Compass Series are high-efficiency floor standing boilers without the install-day surprises. So you can replace the boiler, not the room.
Built for real-world replacement
Most boiler replacements involve older homes, tight spaces, existing floor-mounted systems and piping layouts that can’t be redesigned.
NTI Compass adapts to those realities instead of forcing rework.
Designed to fit and simplify
- Floor-standing design drops into existing footprint
- Flexible left or right piping connections
- No wall construction or stands required
- No major re-piping needed
- Integrated ECM pump and primary/secondary piping
- Startup wizard simplifies commissioning
- Built-in Wi-Fi diagnostics for setup and service
Flexible options for the job
NTI Compass is available in heat-only and Combi configurations, with multiple capacity options to help contractors match output to the application. Combi models provide space heating and domestic hot water from a single unit without a separate tank, while maintaining the same footprint and install logic across the line.
