How efficient is the boiler?
Navien LCB700 boilers are highly efficient, as you can see by the seasonal efficiency of 93% and ErP A-rating for heat.
Will this size boiler suit my home?
An output rating of 21 kW makes this model suitable for homes with a lower demand for heating and hot water but as a regular system should only be installed into larger properties with space to spare.
What options does this boiler come with?
There’s a variety of choice in the LCB700 range as you can choose between an internal or external model, system or regular boiler as well as a range of outputs. If this 21 kW model isn’t powerful enough for your property, then the LCB700 range also includes models with output ratings of 28 kW and 36 kW.
Where can this boiler be installed?
Designed for internal installation, the LCB700 unit can be placed in a kitchen or utility room and is able to fit underneath a standard kitchen worktop to help save space in the home.
Will this boiler save me money?
With the LCB700, you’ll be saving straight away as the compact size and lightweight (67kg) makes for a simple installation. Once installed, the high efficiency rating means that your energy bills will be kept to a minimum.
Is a regular boiler suitable for my home?
Regular boilers (also known as conventional, traditional and heat only boilers too), 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. This means it is not really suitable for smaller homes or homes where space may be limited.
What are the key features of the LCB700?
The LCB700 brings the revolutionary power of blue flame technology to the forefront of the boiler industry. Also featured are smart controls to eliminate the need for an additional thermostat, 2 channel system with separate options for heating and water temperatures and there’s also zone control which allows you to control the temperature in 3 areas of the home individually.
More features include a stainless steel heat exchanger, a combined pipe and condensate drain reducing the number of pipes without compromising performance and making for a quicker installation, the lowest NOx emissions on a boiler (57mg/kWh), geofencing capability which makes sure that you’re never heating an empty home and a smart forecast check allowing the boiler to heat your home, according to the forecast and weather outside.
Does this boiler come with a warranty?
A lengthy 10 year warranty is available as standard with the LCB700 regular boiler, ensuring that you’re well covered by Navien.
