Navien NCB 23kW System Boiler
The Navien NCB 23kW System Boiler has been designed to be compact and lightweight so that it can be wall-mounted in the space of your standard kitchen cupboard, out of sight, out of mind.
With an output of 23kW for central heating, this system boiler has the ability to heat a smaller home with up to 15 radiators. If your home has a higher demand for central heating the Navien NCB system gas boiler range also includes a 28kW and 33kW option.
System boilers are ideal for homes with a high demand for instant hot water. This is thanks to the additional hot water cylinder that is installed alongside your boiler unit. However, it is important to remember that you will need additional space in your home for this hot water cylinder.
For this reason, system boilers are not recommended for homes with limited space. On the plus side, if your home has limited space, the Navien NCB range is also available as a combi boiler, so there is an option for everyone.
