Putting hot water first: Navien ON

Navien has renamed the two leading models in its NCB range of condensing gas boilers as the NCB700 ON and NCB500 ON respectively. This coincides with the company’s introduction of ‘Navien ON’ – a new technological concept dedicated to putting hot water first.

Inspired by the infinity symbol and its similarity to the letters ‘O’ and ‘N’, the company created ‘Navien ON’. Th company says this reflects the boilers’ ability to deliver rapid hot water, constant temperatures and hot water for up to three showers at once.

Commenting on the new concept, Jason Davies, National Business Manager at Navien, said: “By putting hot water first, Navien ON maximises comfort, alleviating the stress from everyday life. We’ve successfully created an energy efficient and futureproof method of prioritising hot water performance – which should be embraced by installers and homeowners alike. Thanks to Navien ON, the possibilities are infinite.”

The NCB700 ON combi gas boiler maximises recirculation of domestic hot water (DHW) to reduce water wastage and offer flow rates up to 22 litres per minute (at 35°C temperature rise). The company says it also dramatically reduces gas usage, saving 38% on average per year.

The boiler also features a turndown ratio of 15:1, is hydrogen-ready (20% blend) and can achieve ErP A+ when used with Navien’s Smart Plus controller. It is available in two models capable of delivering up to 42kW and 54kW of hot water respectively.
