MAXIMUM POWER AT MINIMAL COSTChoosing Navien is a smart choice for keeping heating costs down.

For every £1.00 you spend on energy, standard boilers provide only £0.65 worth of heat, significantly wasting energy and money.

By comparison, the LCB700 provides £0.93 worth of heat, losing only a marginal amount in the process. Making it a clear choice for reduced energy bills. Source: Energy Saving Trust. energysavingtrust.org.uk/home-energy-efficiency/boiler-replacement. Upgrade your heating system and save up to £305 per year. Figure based on installing a new, A-rated condensing boiler with a programmer, room thermostat and thermostatic radiator controls from a G-rated boiler with a programmer and room thermostat in a gas-heated, detached property. Savings will vary depending on the size and thermal performance of your home. Figures are based on fuel prices as of April 2018.

EFFORTLESSLY COMBINING HIGH PERFORMANCE, INTUITIVE CONTROLS AND LOW RUNNING COSTS The LCB700 is a boiler you can depend on. Every aspect is considered to provide enhanced performance at minimal expense to both consumers and installers.

The smart way to control your heating.Intuitive control panel features make it easy for everyone to get the most from their boiler.

Now it only takes two to install, not three. Lightweight and easy-to-handle design, optimised for an easy, fast and cost-effective installation.

Fuss-free flue. Either gas or oil will do.Uses a common flue for greater convenience and reduced installation costs.

Introducing the UK’s lowest NOx emissions.At just 57mg/kWh, the LCB700’s NOx emissions are the lowest in the UK oil boiler industry.

Fewer pipes. Fewer problems.Streamlined PRV and condensate drain means less pipework to install and maintain.

Suitable for homes of all shapes and sizes.Venting up to 110m. Centralised flue provided. Either coaxial or twin flue system available.
