Stove liner collapse – burning the wrong fuel
Woodburners and multi-fuel stoves are fantastic. They look good, they’re cleaner and their warmth output is greater than open fires. But…and you knew there was one coming…they can be trouble if you aren’t careful.
Simply put, there is typically a steel liner installed from your stove up your chimney to take away the smoke. And this often catches out new owners of stoves. The problem is that stainless steel doesn’t last forever – and is quickly corroded if you burn wood and coal or smokeless fuel together – even in a multi-fuel stove.
This liner was installed in 2011 and gave up after 5 years. Whilst there is definitely a warranty on most of these flues, there is also a protocol regarding what to burn. Multi-fuel stoves –designed to burn both coal and wood – should only burn one or the other. Combinations of fuel can lead to production of a mild acid that can destroy stainless steel.
Using a reputable HETAS installer, following the instructions regarding the stove use and having the flue regularly swept will help but burning the correct fuel and not mixing fuels is essential – and not something that is widely known.
Unfortunately this customer will have to have her flue replaced and will undoubtedly feel despondent at having to make a further investment. It is the second one this month that our team have been called to sweep and it doesn’t make for good news.
Keep safe this winter – book a sweep now so you’re ready for the cooler season and, if problems occur you have time to resolve them!
