Product Description

The NCB 23kW System gas boiler is a condensing, wall-mounted unit, designed and manufactured by Navien, that has a high seasonal efficiency of 93% and an ErP A rating for heat.

An output rating of 23kW is perfect for smaller homes with 1 bathroom that don’t have such a high demand for heating and hot water. This Navien range of boilers also includes a range of other outputs, including 20kW, 28kW and 33kW. The 20kW is for similar small homes than the 23kW unit, while the 28kW is the best choice for medium-sized homes and the 33kW can meet the high heating and hot water demands of homes with 2 or more bathrooms.

NCB System boilers have a primary and secondary stainless steel heat exchanger, which helps to prevent corrosion and erosion for an extended life and being OpenTherm ready means that it delivers the latest technology to help cut the costs of installation. More features of this boiler include a full-modulation system that continuously optimises its heat output, extended venting up to 20m for flexible installation, optional outdoor weather sensor, a self-diagnosis and error feedback feature for quick troubleshooting and a stylish touch-type control panel for maximum control over the unit. Plus, the NCB 23kW is able to regulate the heating temperature according to changes in outside temperatures, making sure that you never come home to a cold home again.

Being a System boiler means that this boiler directly heats the central heating system and hot water for a storage cylinder. Most of the important parts of the hot water and heating system, such as the pump and expansion vessel, are built into the unit itself, making it quick to install. Thanks to this, you’ll get a faster response to demand for heating and hot water and there’s no need for a feed and expansion tank in the loft.

NCB System boilers are available with a 7 year warranty, which will help to give you the peace of mind that you’re installing a reliable boiler.
