Navien Boilers Prices

Navien Boiler Prices range between £719 and £2,675 without installation.

A global leader in condensing technology, Navien was the first company in Asia to develop and produce a highly efficient and environmentally-friendly condensing boiler. The company offers a small range of gas combi and system boilers, along with oil combi, system and regular boilers available in interior and exterior options. Navien boilers have already taken America and the rest of the world by storm, and the company’s goal now is to become the UK’s number one boiler brand. 

Navien Combi Boilers Price Range – Capable of using Natural Gas or LPG

Navien combi boilers are SEDBUK A-rated, meaning they boast the highest efficiencies for your heating and hot water requirements. In addition to being highly efficient, Navien combi boilers are compact units that can be installed almost anywhere in your property, making them ideal if your home is on the small side. Navien currently offers the NCB Combi range, which comes in four sizes to suit most households and will set you back between £756 and £980, depending on the boiler output you require.  

The Navien combi boiler range includes the following model and output options:    

COMBI GAS BOILER SERIESSIZESSIZE OF HOMEPRICE
Navien NCB Combi 24 – 40kWSmall, medium and large-sized homes with one bathroom.£756 – £980

Navien System Boilers Price Range – Perfect for Homes with High Hot Water Demand

Gas system boilers from Navien can heat your home and provide plenty of hot water whenever you need it, but they require a separate cylinder for storing hot water. That means they need more space than a combi boiler. One of the benefits of Navien system boilers is that they can handle high hot water demand, making them ideal for homes with more than one bathroom. They cost between £719 and £942 and come in a range of outputs, including 20kW, 23kW, 28kW or 33kW.

The Navien system boiler range includes the following model and output options:

Navien NCB System 20 – 33kWSmall, medium and large-sized homes with multiple bathrooms.£719 – £942

Why Choose Navien?

Navien has been operating in the UK since 2014, so its boilers are relatively new in the UK market. But Navien is well-known elsewhere and is responsible for manufacturing the best-selling boiler in the USA. The brand says its products give you the best value, quality and efficiency, plus the installation process is easy and cost-effective. Navien also promises that it selects only the finest stainless steel components to eliminate corrosion and ensure excellent build quality and long-lasting reliability.

Navien is the Fourth Largest Global Boiler Manufacturer

You may not have heard of Navien, but the company has designed and manufactured reliable boilers and easy to install products for over 40 years. Navien manufactures all boiler components to the highest standards to deliver reliability and maximum performance. From the latest oil and gas-firing technology to solar and micro-CHP, Navien develops highly efficient heating equipment and has become the fourth largest global boiler manufacturer. 

Traditional Stainless Steel and Brass Construction

All gas and oil boilers from Navien boast stainless steel and brass construction to prevent corrosion and erosion. They also have a modern and eye-catching design and a stainless steel heat exchanger to maximise reliability and extend the life of each boiler. 

Navien Boiler Warranty  

Navien gas boilers come with a 7-year warranty, and Navien oil boilers are guaranteed for up to 10 years. The boiler warranty is generous and gives you peace of mind that you’ll be covered should your Navien boiler break down due to a faulty component within the boiler. However, Navien requires your boiler to be serviced once a year by a qualified engineer. Otherwise, you’ll invalidate your warranty.
