Product Description
Designed and manufactured by Navien, the LCB700 is a condensing oil-fired system boiler for external floor-standing installation.
How efficient is the LCB700 21 kW?
The LCB700 is a highly efficient unit, achieving efficiencies of 93% and holding an ErP A-rating for heat.
Will an output rating of 21 kW suit my home?
An output rating of 21 kW makes this LCB700 system boiler best suited to smaller homes that don’t have an excessive demand for heating and hot water.
What options are available in the LCB700 range?
Navien’s LCB700 range of boilers are available as both system and regular boilers as well as the option of internal or external installation. There’s also a number of output ratings to make finding a suitable unit much easier. In addition to the 21 kW boiler, there are more powerful 28 kW and 36 kW units available too.
Where can this boiler be installed?
This unit has been designed as an external floor standing boiler. Meaning it can be placed outside in your garden helping to save you that much needed space in your home as well as it being a compact unit helping to save you space in your garden.
Can the LCB700 boiler save me money?
The high efficiency rating of the LCB700 will help to keep your energy bills down to a minimum. The 93% efficiency means that for every £1 spent on heating your home, only 7p is wasted. This is a considerable saving compared to old inefficient boilers with efficiencies of around 60-70%. Also, thanks to its compact size and low weight of 67kg, installation is made simpler which will help to save you money.
Is a system boiler suitable for my home?
System boilers send hot water to the radiators and a sealed hot water storage cylinder using the mains water supply. The important parts of the system are built into the boiler itself, removing the need for any tanks in the loft.
What are the key features of the LCB700?
Navien have made sure that their LCB700 boilers include a number of features to make them as effective and efficient as possible. LCB700 boilers are housed in a simple casing, include smart controls for improved comfort and eliminating the need for an additional thermostat, there’s a 2 channel system to separate heating and water temperatures as well as zone control so that you can set up 3 areas of the home for separate control.
Also featured is a stainless steel heat exchanger for longer boiler life and lower running costs, a combined pipe for PRV and condensate drain reducing the number of pipes without compromising performance and saving space which allows for a quicker and easier installation. The unit features a fuss-free flue, the lowest NOx emissions on a boiler at only 57mg/kWH and geofencing capability to ensure that you never return to a cold house or end up heating an empty home again.
How long is the warranty period?
Available with a 10 year warranty, the LCB700 range of boilers are well covered by Navien long after installation.
