Overview
The NCB300 gas condensing combi boiler is our entry model, which offers the same hot water comfort, powerful heating and flexible installation options as larger models, but in a compact design. This combination of features makes the NCB300 an excellent choice for smaller properties where exceptional levels of reliability and DHW performance are the priority.
Although this boiler is a pared down version of its larger cousins, it still achieves exceptional levels of hot water performance, due to its high-quality construction and high-tech components. There are three sizes of NCB300 available, with DHW outputs of 28kW, 37kW and 41kW to choose from. Plus, each unit benefits from an LCD control panel for comprehensive management.
