Issues following installation of new stove and flue liner

Anonymous user 09/03/2024 - 3.33 PM

Hoping someone can help with this. We had old Coalbrookdale Severn 7KW stove removed (due to corrosion) and replaced with a Wiking Mini 4.5kw. Installers insisted we pay for flue liner pack which we did. They did have alot of issues installing the metal flue pipe down the chimney but succeeded eventually. After 2 weeks the stove's draw was greatly reduced, the glass blackened thick with tar, a real issue to get it off (had to resort to Stanley blade to scrape it) - then liquid tar began to pour through the seal/plate and down the outside of the flue pipe, spattering everywhere when the fire was lit and every time we opened the stove door the room and whole house filled with smoke. Had the installers back umpteen times. Everything we did was questioned, whether we burnt correct wood etc etc. Our wood is bought in as seasoned and we have a fold yard piled high with it, all kept nice and dry...so the issue was not the wood we were burning. Then we were questioned as to how we lit the stove etc..... we had the previous stove 30+ years and never an issue with that so I think we know how to operate a stove. Eventually the liner was removed and hey presto - after a year of hassle - the stove began to operate perfectly. However, in Oct 22 we had major issue under kitchen floor with central heating pipes and stove had to be removed....... our issue now is that we don't want a liner installing, we just want the stove reinstalled as was but all companies saying a liner must be fitted, we are desperate for a liner to not be installed as it caused the issues previously. How do we proceed? Thank you all for answering - we are having our chimney inspected today to check it for leaks - in response to your advice. We believe all of the checks were carried out when new stove and original liner were installed. A rotary cowl was installed at the time. Hopefully getting somewhere now but just wanted to update to say how helpful your advice has proved

Are you a tradesperson and able to answer this question?

That is a tricky one . Really a liner should be fitted . I would have a liner fitted and see how you go as normally a liner is better to use than no liner . We’re you idling the stove meaning was you burning at a low temperature nearly shutting it down as that can cause them kind of problems. Definitely go for a liner and burn your stove hot

Hi. Sounds like big problems. Need to send cctv up to check liner. Liner could be upside down so any liquids run out of liner. Put up co alarm. Mark innes Innes construction

You don’t have to have a liner fitted by law , as long as there are no leaks in the chimney system , however it is better to have one installed. What flue size does the manufacturer recommend ? For 7kw you should have a 150mm liner installed. Also once fitted to stove the installers should then carry out a purge test and flue draught test and record their readings on the commissioning sheet (minimum requirement between 5 / 12 pascals . Also a rotary cowl could be fitted to help with the extraction , hope this helps.

I have had this on similar job. We was called to a job with had tar all dripping down chimney pipe. Stripped it out and the chimney was covered in tar. Needed chemical clean. Falling that, could insulate with chim wrap. Or can use twin wall flue.
