What they don’t know about stives and flues isn’t worth knowing.,

We recently fitted two wood stoves in our cafe. Julian designed and supplied the two flue systems- duraflue silvacore flexi, the duraflue twin wall and all the fittings and fixings. It’s a bit of a minefeild out there with so many companies offering inferior products. Stovefitters supply only quality products at competitive prices. It was reassuring to discover them and their range of superb quality products. We can highly recommend them. They were thorough and professional. They were quick to respond and called me back when requested on numerous occasions to discuss our requirements- nothing was too much trouble and their knowledge is extensive. Their quote was very competitive. I am so pleased we discovered this company- they made the job so very straightforward. We are very pleased with our stoves now they’re installed.

Twin wall flue & Saltfire vision stove from Stovefitters.

I have recently bought a Saltfire stove and twin wall flue system from Stovefitters. The whole process was pretty good from start to finish, had a couple of problems with the fitting process, but these were resolved quickly. Everyone that I dealt with were spot on. Julian the boss,was very approachable, always answered the phone and was very helpful when advice was needed. The Saltfire stove is perfect for our needs, is so easy to light and looks the business. We have been extra cosy since,we started using it. A perfect addition to our household.

Top Quality Item

I bought this item in black for securing my twin wall flue. The build and paint finish on this item is of a high standard. The securing bracket allows you to manoeuvre the clamp left or right so that it is exactly where you want, as well as adjusting for height. This item provides a very secure fit to your twin wall flue.
