Navien Boiler Warranty

Updated: 27th March 2024

What is a boiler warranty?

Your boiler is one of the most important appliances in your home and a significant investment, so you need to be sure you're making the best choice for your home in the long term. In addition to the performance power and energy efficiency, a big indicator of the quality of your boiler is the length of the warranty included.

Should the boiler need repairing because of a manufacturer's defect during the warranty period, you won't need to pay for it to be repaired or replaced. The longer the warranty, the more confidence the manufacturer has in the quality of their product and the more peace of mind you'll have. Warranty periods tend to range from 1-10 years, but there may be terms and conditions attached which you need to be aware of. Here's what you need to know and about Navien boiler warranties.

Who are Navien?

Founded in 1978, just 10 years later KyungDong Navien (KD Navien) became the first company in Asia to manufacture an environmentally-friendly condensing boiler. Today the company exports to 30 nations around the globe including North America, Europe, China, and Russia.

Standard Navien warranty

Your Navien boiler is protected for 6 years after installation against manufacturing defects.

What's covered by the warranty?

Navien's warranty covers the boiler's components and if anything does wrong due to a manufacturer's defect, your boiler will be protected. However, if the breakdown is caused by a poor installation or sludge in the central heating system you may not be covered.

Terms and conditions

Your boiler is covered by a warranty, but if you don't satisfy the manufacturer's terms and conditions you may find that you're not protected when it you need it. It's always worth a look at the small print to be on the safe side. With Navien, your boiler will need to be serviced by a Gas Safe registered engineer every 12 months to ensure the warranty remains valid.
