Navien LCB700 36kW Internal Combi Oil Boiler

This is the Navien LCB700, the most powerful internal combi boiler in the range with a central heating output of 36 kW. The LCB700 is a condensing combi oil boiler designed for floor-standing installation.

How efficient is the Navien LCB700?

The Navien LCB700 range delivers highly efficient performance as shown by the ErP A-rating and 93% space heating efficiency. The addition of a Navien Smart Plus thermostat takes this efficiency further increasing the ErP rating to an A+ with 98% efficiency.

Is the output rating suitable for my home?

The LCB700 36 kW is the most powerful option in this range of Navien combi boilers. The central heating output goes up to 39 kW when operating at 50/30°C. Homes with as many as 20 radiators could consider a combi boiler of this size.

Are other outputs available in the LCB700 range?

If you’re looking for a combi boiler with a smaller output then there are two other models in the range, these have outputs of 21 kW and 26 kW. Additionally, there are also external models if there isn’t much free space in your property. Should you have a high demand for domestic hot water (more than 2 bathrooms) then LCB700 system and regular boilers are available too.

Is a combi boiler suitable for my home?

Combi boilers are the most popular heating system in the UK and are perfect for properties with a low to moderate demand for hot water. Unlike system and regular boilers, combi boilers don’t store domestic hot water in a cylinder. In terms of benefits this means that you never have to wait for hot water. However, for a strong flow rate to several outlets at the same time, a hot water cylinder is the best option.

How long is the warranty period?

Featuring a 10 year warranty, you will be covered by Navien long after the installation of an LCB700 combi boiler.

What are the key features of the Navien LCB700?

Navien LCB700 combi boilers have a number of features that make them efficient and highly reliable units. Thanks to the built-in Smart Auto Mixing and a Smart Auto Flow Control Valve allows the LCB700 to deliver a consistent temperature when hot water is needed at several outlets. They also feature a stainless steel heat exchanger and blue flame technology to provide industry-leading efficiency.

How big is the Navien LCB700?

This is an internal combi boiler with compact dimensions of 600 x 600 x 860mm (HxWxD) which means that it won’t take up much space.
