An A+ energy rating signifies high efficiency in heating. For the Navien LCB700, this rating is achieved when the boiler is installed with a minimum of three Navien Smart Plus room thermostats, optimizing energy usage.
With a 36kW output, this combi boiler is designed to provide ample heating and hot water for a wide range of properties, including larger homes, offering powerful performance.
HVO compatible means the boiler can run on Hydrotreated Vegetable Oil, a sustainable and cleaner-burning alternative to traditional heating oil, making it a future-proof option.
No, a combi (combination) boiler provides both central heating and hot water directly from the unit, eliminating the need for a separate hot water cylinder.
It is recommended to have the boiler serviced annually by a qualified heating engineer to ensure it operates safely and efficiently.
Warranty details are typically provided by the installer or manufacturer upon purchase and installation. Annual servicing by an accredited engineer is often a condition of the warranty.
No, installation must be carried out by a qualified and registered heating engineer. Incorrect installation can be dangerous and will invalidate the warranty.
Check the oil supply, ensure the thermostat is calling for heat, and verify electrical connections. If the problem persists, contact a qualified service engineer.
Verify the hot water settings on the thermostat and boiler. Check for any isolation valves that may be closed. A blockage in the system or a fault with the heat exchanger may require professional inspection.
Consult the boiler's user manual for the specific error code. Common codes may indicate a simple reset is needed, while others require a service engineer to diagnose and repair.
Listen for the type of noise (e.g., banging, whistling). This could indicate low water pressure, air in the system, or a component issue. Check system pressure and bleed radiators. Persistent noise requires professional assessment.
Setup: The Navien LCB700 Blue Flame boiler is designed for ease of installation, featuring a lightweight construction and combined PRV/condensate drain. It offers flexible pipework arrangements and flue venting options (up to 21m horizontally or vertically). Professional installation by a qualified heating engineer is mandatory to ensure safety, optimal performance, and warranty validity.
Compatibility: This boiler is compatible with standard oil fuel supplies and is HVO (Hydrotreated Vegetable Oil) ready, indicating future fuel flexibility. For achieving the A+ energy rating, it must be installed with specific compatible controls, such as the Navien Smart Plus room thermostats (minimum of three required for the A+ rating).
Care: Regular annual servicing by a qualified engineer is essential to maintain efficiency, safety, and longevity. Cleaning the exterior with a damp cloth is generally sufficient for the casing. Avoid using abrasive cleaners. The stainless steel heat exchangers are designed for durability, but their performance can be maintained by ensuring the system is properly flushed during installation and servicing.
