Navien has achieved international recognition for its state-of-the-art heating technology, which is exemplified by the company’s range of NCB condensing gas boilers. Comprising four Combi and four System models, with outputs from 20 to 40kW, the A-rated boilers deliver outstanding ErP efficiencies from a standalone unit.
In addition to low NOx emissions (class 6), all NCB gas Combi boilers are water resistant to an IPX5 rating offering peace of mind, while each unit is easy to handle for simple, fast and cost-effective installation. Plus, the range is also “OpenTherm” ready, allowing for instant access to the latest heating control technology.
Every Navien NCB gas boiler boasts a stainless steel heat exchanger and digital display panel, with 40kW models benefiting from a turndown ratio of 10:1. These quiet running units use 60/100mm plastic flues and are supplied with a free LPG conversion kit.
All boilers benefit from a modern full text display, which makes it easy to view useful information on the user’s domestic hot water usage, and supply/return water temperatures, while an ECO function reduces energy and water used.
