Product Description

The NCB 34kW Combi gas boiler is a highly efficient boiler, designed and manufactured by Navien, that has an efficiency rating of 93%, giving it an ErP A rating for heat and hot water.

An output rating of 34kW makes this an ideal boiler for larger homes, with 2 or more bathrooms, that have a high demand for heating and hot water. In addition to this 34kW model, 24kW and 28kW boilers are available for medium-sized homes, while the 40kW output rating is best for large homes.

Navien NCB boiler features 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. You can choose between natural gas and LPG and, finally, it comes with an OpenTherm to give you the latest control technology that will help to cut the costs of installation.

As a Combi boiler, this unit doesn’t require an external water tank or storage cylinder as everything is within the unit itself, which will save you space around the home.

The NCB 34kW Combi is available with a 7 year warranty, showing the confidence that manufacturer, Navien, has in this boiler.
