Know your way around a Navien boiler? 🛠️

From the heat exchanger to the expansion vessel, you’ll know a boiler’s made up of several key components that work together to keep your customers’ homes warm and the hot water flowing. But do you know where each part is in one of our boilers?

Go on, test your knowledge and see how many parts you can identify. Let us know in the comments! 👇

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.
