While this LCB700 boiler is an external regular boiler, the range also includes units designed for internal installation as well as system boiler. There are also multiple output ratings in addition to the 36 kW boiler: 21 kW and 28 kW. So, if a 36 kW boiler would be too powerful for your home, there’s likely to be another unit in the LCB700 range for your home.

As well as this, it is a compact unit that weighs 67kg allowing an easy installation that can save you both time and money.

Is a regular boiler suitable for my home?

Regular boilers are installed as part of a central heating system that incorporates a boiler, extended controls, a hot water cylinder - which is often fed by a cold water storage cistern located in the loft - and a feed and expansion cistern, also located in the loft. As a result of needing all these parts, they’re not suited to properties where space is limited and are best placed in homes with a high demand for heating and hot water.

What are the key features of the Navien LCB700?

Navien LCB700 boilers have many key features and offer the revolutionary power of blue flame technology. Features of the LCB700 include smart controls with a text-driven menu for greater comfort and control, a 2-channel system with separate options for heating and water temperatures, zone control that makes it possible to set up 3 areas of the home as zones and control each one. This unit features venting up to 110m (Big Ben is 96m) with a centralised flue provided as well as a coaxial or twin flue system. Additional features include a stainless steel heat exchanger that will increase boiler life as well as lowering running costs, 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), a geofencing capability means that the heating will turn on or off depending on your location and a smart forecast so that the boiler can heat your home according to the forecast and weather outside.
