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 Boiler 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 SERIES | SIZES | SIZE OF HOME | PRICE |
|---|---|---|---|
| Navien NCB Combi | 24 – 40kW | Small, medium and large-sized homes with one bathroom. | £756 – £980 |
Navien System Boilers Range – Perfect for Homes with a large 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:
| SYSTEM GAS BOILER SERIES | SIZES | SIZE OF HOME | PRICE |
|---|---|---|---|
| Navien NCB System | 20 – 33kW | Small, medium and large-sized homes with multiple bathrooms. | £719 – £942 |
Navien Oil Boilers Range – Interior and Exterior Options
A Navien oil boiler could be perfect for your home and needs if you’re not connected to the gas network and require a new boiler. The range includes oil combi, system and regular boilers presented in smart and simple casings, and all models are available in interior and exterior options to suit your requirements. Navien’s oil boilers feature a smart control panel and provide up to ERP A+ when used with a Smart Plus control pack.
