Put hot water first with our NCB ON range. đźšż

Our Navien ON technology makes the most of domestic hot water (DHW) recirculation, helping to reduce water waste while delivering hot water fast. It keeps temperatures consistent and can even supply up to three showers at once. That means more everyday comfort for your customers, with less hassle.

Efficient, future-ready hot water is here – so why not embrace it?

Great service starts with great support. 👏

Hear from Mathew, our Regional Sales Manager for Northern Ireland, and Sam from PW Boilers, as they share their experience of working with Navien UK.

From fast responses to reliable assistance when it matters most, and well-priced boilers that are backed by a 5-year parts and labour warranty, having the right support behind every installation makes all the difference.

Register your installations on the go – even after leaving the site!

We’ve updated our warranty app to make your life a little easier. Where you’d have to scan the barcode on the side of the boiler in the app while still on site, now it’s even more convenient.

→ Simply take a photo of the barcode while on site.
→ Register the installation later, at a time that suits you.
→ Enjoy greater flexibility and less pressure to complete registration before leaving the job.

It’s a small update that makes a big difference to your working day.
