When a customer of ours found that a competing boiler was not up to the task of heating their large residential property, the Navien NCB700 ON Combi Crossover provided a viable solution. With 30 radiators across three floors, they were concerned that there wouldn’t be a boiler powerful enough for the job, but the 54kW capacity of the NCB700 ON Combi Crossover proved that it’s not just a competent combi boiler, but a choice that outperforms its competition.

The biggest problem for the customer was that the third floor bathroom wasn’t receiving any hot water. In a house with three bathrooms, this was essential for the upstairs living space, and deserved a simple solution. The 54kW power of the NCB700 ON Combi Crossover was unrivalled in its power, being able to supply all three bathrooms with hot water at once, as well as their radiators – a definite upgrade from the customer’s previous boiler.
