📏 Choose Your NCB-H Size
| Model | Best for | Heating output (net AHRI) | Hot water at 45°F / 70°F rise |
|---|---|---|---|
| NCB-190/060H | Condo / 1 bathroom | 49,000 BTU/h | 6.4 / 4.1 GPM |
| NCB-190/080H | Small home, 1–2 bathrooms | 64,000 BTU/h | 6.4 / 4.1 GPM |
| NCB-240/110H | Medium home, 2 bathrooms | 89,000 BTU/h | 7.9 / 5.1 GPM |
| NCB-240/130H | Large home, 2–3 bathrooms | 104,000 BTU/h | 7.9 / 5.1 GPM |
| NCB-250/150H | Large home, high hot water use | 120,000 BTU/h | 8.4 / 5.4 GPM |
Home size is a guide only. We confirm the right model with a heat-loss calculation before installation.
💡 Replacing a boiler and a rented water tank? The NCB-H replaces both with one unit and ends the tank rental. For homes with 3+ bathrooms or big tubs, a heat-only boiler with an indirect tank gives more stored hot water. See Combi Boiler Installation Toronto.
