Why it's not good to slumber your stoves!

Slumbering is when an appliance is purposely set at a low or minimum output normally for overnight burning or for a long period of time to be revived in the morning or later in the day without the need for relighting. 

There are problems associated with using an appliance for extended periods at low output especially if the appliance is not designed to operate in this way. 

Running an appliance at low outputs can lead to incomplete combustion, especially when burning a high volatile content fuel such as wood logs. This leads to the formation of sooty and/or dry deposits on the flue lining as well as increased levels of carbon monoxide and particulates.

when appliances are used at low output for extended periods of time the temperature of the chimney reduces and there is a tendency for the products of combustion to also be lower in temperature which will lead to an increased likelihood of condensation forming in the chimney. The condensation together with deposit in the flue that are acidic risk the corrosion of metallic components like the stove, and flue flexi liner etc. 

Flexi liners whilst being easier to install and replace are not designed to last the life of the building, but may if used correctly last in excess of 10 years. If slumbering coal or logs for a long period of time this can cause corrosion and damage a line in less than a few years.  

The efficiency and life expectancy of any chimney is dependent upon correct use and maintenance. Masonry and pre-cast chimney products – whilst usually offering long life and high resistance to risk of corrosion – tend to involve more installation work when compared with metallic chimney systems.
