Navien LCB700 21kW Internal Oil Combi Boiler

More About The Navien LCB700 21kW Oil Combi Boiler

Fitted with Navien’s stainless steel heat exchanger

The heat exchanger is a critical factor in the performance of Navien’s LCB700 21kW oil combi boiler. It is a premium, corrosion and erosion-resistant 100% stainless steel heat exchanger. This ensures the system’s durability and long-term reliability. It allows each of these boilers to come with a standard 10-year warranty.

The choice of high-grade 100% stainless steel for the heat exchanger is deliberate. This is due to its durability, lightweight characteristics, and minimal reaction to impurities in water. Its ability to handle diverse pH levels is crucial in sustaining the high performance of Navien’s boilers over their lifespan.

Sean Keleher, Technical Manager at Navien, said: “We only use 100% stainless steel, as it offers fantastic resistance to corrosion. Engineers will know any fouling on the surface area will significantly reduce the heat transfer characteristics, which is a significant disadvantage when a boiler is required to operate at a high flow rate; however, stainless steel heat exchangers operate effectively whatever the velocity of the system water.”

Easy operation

Operating the LCB700 21kW oil combi boiler is easy with its text-based, on-unit controls. It allows intuitive control and live fuel consumption figures.

The LCB700 is compatible with a variety of smart thermostats for even greater control. Navien also has its own Smart Plus Controller. This integrates perfectly with the LCB700 oil combi boiler. It also has Geofencing capability to allow your boiler to turn on when you are close to home, depending on the temperature, of course. It also checks the OpenWeatherMap to determine how best to respond to upcoming changes in local temperature.

Boiler reset

Like all modern devices, sometimes a boiler needs to be reset. The LCB700 can easily be reset on the boiler control panel by pressing the Back button for a few seconds. It’s super easy.

Engineering excellence

The built-in Smart Auto Mixing and Smart Auto Flow Control Valve delivers consistent flow temperatures across multiple outlets.

Classic yet modern design

The Navien LCB700 is stylish in monochrome. It has an easy-to-use, text-driven, smart control panel at the front of the unit. It will look good in any room, fitting in perfectly in kitchens or utility rooms.

Manufactured in South Korea

The Navien brand is relatively new to the UK market, but they have been making high-quality boilers for over forty years. Their industry-leading boiler manufacturing facility just outside of the South Korean capital, Seoul is the largest boiler manufacturing plant in the world. South Korea has a reputation for innovative technology, and that is demonstrated across the Navien brand.

Boilers and parts are well-stocked across the UK and can be obtained from retailers, including Plumbase and Screwfix.
