Navien LCB700 28kW Internal Combi Oil Boiler

Manufactured by Navien, the LCB700 is a condensing combi boiler with a maximum central heating output of 30.3 kW, designed for internal floor-standing installation.

How efficient is the Navien LCB700?

The Navien LCB700 range delivers highly efficient performance as shown by the ErP A-rating and 93% space heating efficiency. The addition of a Navien Smart Plus thermostat takes this efficiency further increasing the ErP rating to an A+ with 98% efficiency.

Is the output rating suitable for my home?

This LCB700 model has an output rating of 28 kW and is able to achieve a maximum output of 30.3 kW at a temperature of 50/30°C. A combi with a central heating output of this level can be well suited to homes with up to 15 radiators.

Are other outputs available in the LCB700 range?

In addition to this model, Navien LCB700 combi oil boilers are available with 21 kW and 36 kW central heating outputs. And that’s not all as there are also system and regular units designed for either internal or external installation.

Is a combi boiler suitable for my home?

A combi boiler is a compact heating system that directly heats the central heating system while also providing domestic hot water on demand. With a combi boiler, you’ll be saving room around the home as there’s no need for a tank in the loft or a cylinder. While this makes combi boilers great for smaller properties with 1-2 homes they’re unable to meet the demand of larger properties.

How long is the warranty period?

Available with a lengthy 10 year warranty as standard, Navien will see that you’re well covered after the installation of an LCB700 boiler.

What are the key features of the Navien LCB700?

Navien LCB700 boilers boast a stainless steel heat exchanger and blue flame technology which allows the range to deliver industry-leading efficiency. Additionally, Navien blue flame technology also delivers low NOx emissions.

Choose to have a Navien Smart Plus thermostat alongside the boiler and efficiency is increased. The unit will then also be able to monitor the weather forecast meaning that when cold conditions are forecast, the central heating will adjust automatically.

How big is the Navien LCB700?

Thanks to dimensions of 600 x 600 x 860mm (HxWxD) the Navien LCB700 is a compact combi oil boiler that offers flexible installation.
