LCB700 28kW External Combi Oil Boiler

Designed and manufactured by Navien, the LCB700 28 kW External is a highly efficient condensing combi oil boiler for installation outside.

How efficient is the Navien LCB700?

Built with efficiency in mind, Navien LCB700 oil boilers can help to lower your energy bills as well as your carbon footprint. The unit has been awarded an ErP A-rating and delivers 93% efficiency. You can increase efficiency even further to 98% by installing a Navien Smart Plus thermostat.

Is the output rating suitable for my home?

The maximum central heating output of this boiler is 30.3 kW which makes it well suited to homes with around 15 radiators.

Are other outputs available in the LCB700 range?

Navien LCB700 External boilers are also available with a lower output rating of 23 kW for homes with up to 10 radiators or a higher 39 kW output which suits larger heating systems. Also, LCB700 boilers are available for internal installation if you’d prefer.

Is a combi boiler suitable for my home?

A combi boiler is a great option for small to medium-sized homes with 1-2 bathrooms. They deliver heating and hot water on demand and don’t need to be installed alongside a cylinder. While they are compact space-saving units, a combi boiler won’t be able to meet the hot water demands of larger homes with multiple bathrooms.

How long is the warranty period?

Featuring a 10 year warranty as standard, you’ll be covered by Navien long after the LCB700 has been installed.

What are the key features of the Navien LCB700?

Navien have included a range of features that make this a highly efficient oil boiler. Firstly, it boasts blue flame technology which helps to increase efficiency and deliver low NOx emissions. It has a function for delivering quick domestic hot water and has a smart control panel which displays the amount of oil being used. Finally, a stainless steel heat exchanger helps to prevent corrosion and extend the lifetime of the boiler.

How big is the Navien LCB700 28 kW External?

The Navien LCB700 28 kW has dimensions of 650 x 673 x 900mm (HxWxD). This is only the boiler itself and doesn’t include the space needed for the oil storage tank.
