Why We Recommend This System
Our installer's perspective:
- NTI is a Canadian boiler manufacturer with products designed for our climate.
- The TRX consistently performs well with excellent reliability in the field.
- For hydronic heating, it's hard to beat the combination of efficiency and comfort.
- Local manufacturing means parts availability and good technical support.
When it might not be the best fit:
If you have forced-air ductwork, a furnace or heat pump makes more sense. Boilers are for hydronic (water-based) heating systems.
Alternative: If you're converting from boiler to forced-air, consider a Rheem furnace with new ductwork.
