The Navien LCB700 36 kW External is a condensing combi boiler that runs on oil and has been designed for external installation.

How efficient is the Navien LCB700?

If this model is too powerful then models with maximum central heating outputs of 23 kW and 30.3 kW are also available. This means there’s a Navien LCB700 External oil boiler for homes of just about any size. In addition, internal models are also available.

Is a combi boiler suitable for my home?
