Product Description

The LCB700 28 kW is a condensing oil-fired regular boiler from Navien that has been designed for external installation.

How efficient is the LCB700?

A seasonal efficiency of 93% and ErP A-rating for heat makes the Navien LCB700 a highly efficient boiler.

Will this size boiler suit my home?

An output rating of 28kW makes this LCB700 oil boiler perfectly suitable for medium-sized homes that don’t have such excessive demand for heating and hot water.

Is there a boiler in the LCB700 range to suit my home?

The Navien LCB700 range has a variety of options so that there’s a boiler to suit almost any home. While this unit is an external regular boiler, internal versions as well as system boiler s are available too. There’s also a range of different outputs, including 21 kW and 36 kW, in addition to this 28 kW model.

Where can this boiler be installed?

As an external boiler, the LCB700 has been designed for outdoor installation in a back garden. Thanks to its compact size it won’t take up much garden space either.

Could an LCB700 boiler save me money?

Thanks to being highly efficient, the LCB700 could save you money on your energy bills all year round. To put the 93% efficiency into context, for every £1 you spend heating your home only 7p is wasted - you’re unlikely to find an oil boiler achieving efficiencies higher than this. As well as the savings on energy bills, the compact size and low lift weight of 67kg could help to save you time and money on the installation too.

Is a regular boiler suitable for my home?

Regular boilers need to be installed as part of a heating system alongside a hot water storage cylinder, cold water storage tank and a feed and expansion tank. Due to all of these parts, regular boilers aren’t suitable for smaller homes or properties where space is limited.

What are the key features of the LCB700?

LCB700 boilers boast many features, such as revolutionary power of blue flame technology, smart controls with a text-driven menu for greater comfort and control, a two channel system with separate options for heating and water temperatures, zone control which makes it possible to set up 3 areas of the home as zones and control each one.

This unit features venting up to 110m (Big Ben is 96m) with a centralised flue provided as well as a coaxial or twin flue system. Additional features include a stainless steel heat exchanger that will increase boiler life as well as lowering running costs, a combined pipe for PRV and condensate drain to reduce the number of pipes without compromising performance, a fuss-free flue, the lowest NOx emissions on a boiler (57mg/kWH), a geofencing capability means that the heating will turn on or off depending on your location and a smart forecast so that the boiler can heat your home according to the forecast and weather outside.

Does this boiler come with a warranty?

Navien LCB700 boilers feature a 10 year warranty as standard, so in the unlikely event of an issue you’re well covered.
