Product Description

Designed and manufactured by Navien, the NCB 28kW Combi gas boiler is a wall mountable unit that comes with a high efficiency rating of 93% and ErP A rating.

With a 28kW output rating, the Navien NCB is the perfect size for medium-sized homes that don’t have an excessive need for heating and hot water. In addition to this 28kW model, the NCB range also includes 24kW, 34kW and 40kW units. The 24kW model is the best option for smaller homes with 1 bathroom and not such a high demand for heating and hot water. If you live in a large home, with 2 or more bathrooms, then you should consider the 24kW or 40kW NCB boilers.

Some of the features you’ll find in Navien NCB boilers, include it being integrated with a primary and secondary stainless steel heat exchanger for protection from corrosion, a full modulation system continuously optimizing its heat output, extended venting up to 20m to allow for a flexible installation, optional outdoor weather sensor, a self-diagnosis and error feedback feature for quick troubleshooting, a stylish touch-type control panel to give you maximum control over the unit and heating temperature regulation based on the conditions outside. It’s also available as a natural gas or LPG boiler and comes with an OpenTherm to give you the latest control technology that will help to cut the costs of installation.

As a Combi boiler, the NCB, is a water heater and central heating boiler wrapped up into one unit. Combi boilers are real space savers as there’s no need for a hot water cylinder, perfect for smaller homes that don’t have much space to spare.

You’ll be getting a 7 year warranty with the NCB 28kW Combi, which will give you complete confidence in this reliable boiler.
