Fitting comfortably inside a cupboard with ease due to a compact 283mm depth, this energy-saving boiler boasts the same high-quality construction as the NCB700.
It can achieve hot water outputs of up to 41kW while boasting an industry-leading ErP efficiency of 93%. Plus, thanks to Navien's state-of-the-art flow adjustment valve and auto mixing valve, the NCB500 is able to provide lots of hot water, with no changes in DHW temperature or flow rate.
The boiler also features a built-in, text-driven digital display panel; simple to program and use, it includes a two-channel timer and allows energy usage to be monitored with ease.
