The Navien 28kW Oil Combi Boiler is designed for homeowners seeking an efficient and powerful heating and hot water solution without a separate cylinder. Its key benefit is an A+ energy rating (when installed with 3 Smart Plus room thermostats), offering significant energy savings. A potential caveat is that the optimal energy rating requires specific thermostat integration.

HVO stands for Hydrotreated Vegetable Oil, a biofuel that can be used as a direct replacement for, or blended with, traditional heating oil. It offers a more sustainable and cleaner-burning alternative.
No, a combi boiler, by definition, provides both central heating and hot water on demand without the need for a separate hot water storage cylinder.
The A+ energy rating is achieved when the boiler is installed with 3 Navien Smart Plus room thermostats and is configured correctly.
The Navien LCB700 Blue Flame boiler supports flue venting up to 21 meters in both horizontal and vertical configurations.
With a 28kW output, this combi boiler is suitable for a wide range of properties, including larger homes, providing ample heating and hot water capacity.
Blue Flame technology offers superior combustion efficiency and significantly reduces NOx (Nitrogen Oxide) emissions, contributing to better air quality and a lower environmental impact.
Check the main power supply and ensure the system is switched on. Verify that there is sufficient oil in the tank. Inspect for any error codes displayed on the control panel and consult the user manual.
Ensure the hot water demand does not exceed the boiler's 28kW output. Check if the boiler is in 'heating only' mode. If the issue persists, a service check may be required to inspect the heat exchanger and internal components.
Verify that the central heating circuit is properly functioning and that radiators are not airlocked. Check thermostat settings and ensure they are calling for heat. System pressure should be within the recommended range.
Refer to the Navien LCB700 user manual for a specific breakdown of error codes and their corresponding troubleshooting steps. Contact a qualified engineer if the issue cannot be resolved using the manual's guidance.
Setup: The Navien LCB700 Blue Flame boiler features a lightweight design and flexible pipework arrangements, simplifying installation. Integrated features like a combined PRV/condensate drain further streamline the process. For optimal performance and to achieve the A+ energy rating, installation with 3 Navien Smart Plus room thermostats is recommended.
Compatibility: This boiler is HVO (Hydrotreated Vegetable Oil) compatible, allowing for a more sustainable fuel choice. It is designed to provide heating and hot water for various property sizes. Ensure your existing oil supply and tank infrastructure meet the requirements for this boiler.
Care: Regular servicing by a qualified technician is essential to maintain efficiency and longevity. The stainless steel heat exchangers are designed for durability, but periodic checks for any debris or blockages, especially in the flue system, are advised. Consult the user manual for specific cleaning instructions for the exterior.
