Product Description

Designed and manufactured by Navien, the LCB700 36 kW is the most powerful boiler in the range. It is a condensing system boiler that runs on oil and has been designed for internal floor-standing installation.

How efficient is the Navien LCB700?

A seasonal efficiency rating of 93% and ErP A-rating for heat make this a highly efficient boiler that will help to keep your energy bills down as much as possible.

Will this size boiler suit my home?

The output rating of 36kW makes this model best suited to larger homes with 2+ bathrooms and a high demand for heating and hot water.

Is there a boiler in this range to suit my home?

If this 36 kW model is too powerful for your home, then the LCB700 range also includes models with outputs of 21 kW and 28 kW, making it easier to find a suitable boiler. As well as this system boiler, a regular boiler is also available and there’s also the option of a model designed for external installation too.

Where can this boiler be installed?

This LCB700 model has been designed for internal installation in a utility room or kitchen and thanks to its compact size it can be placed under a kitchen worktop to save space.

Will this boiler save me money?

A high efficiency rating means that the Navien LCB700 is able to help reduce your energy bills. The 93% efficiency rating simply means that for every £1 spent on heating your home, only 7p of that goes on wasted energy. That’s quite a saving when compared to the 60-70% efficiency ratings of older units.

Is a system boiler suitable for my home?

System boilers are best suited to medium-larger homes as they’re able to meet the higher demands for heating and hot water. System boilers directly heat the central heating system and hot water for a storage cylinder with most of the important parts, such as the pump and expansion vessel, being built into the boiler itself, making it quicker and cleaner to install - also meaning that you’ll get a faster response to demand for heating and hot water. Additional space is needed for the installation of a hot water cylinder.

What are the key features of the LCB700?

The Navien LCB700 28 kW has blue flame technology, smart controls for improved comfort, 2 channel system with separate options for heating and water temperatures and zone control which gives you the ability to control 3 areas of the home individually.

The unit also boasts a stainless steel heat exchanger that resistant to corrosion for longer boiler life, 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), geofencing capability and also a smart forecast check so that the boiler can heat your home, according to the forecast and weather outside.

Does this boiler come with a warranty?

With a lengthy 10 year warranty available on the LCB700, you’ll be well covered by Navien long after the installation.
