Stovefitters Warehouse were Brilliant!

Stovefitters warehouse have been brilliant!
We sent Julian some simple drawings and measurements and he designed us the perfect systems for two wood burning stoves, complete with list of parts and a computer produced diagram of the finished article. They then put the order together which we received promptly and we’ll packaged. Great British made quality too! The twin wall Duraflue is very nicely made with very clean lines and is very simple to install.
We changed our mind a couple of times but nothing was too much trouble.
Julian and Arran dealt with our issues promptly and very professionally. Their knowledge about stoves and flues is second to none!
We are extremely pleased with the goods and service we received. We would not hesitate in recommending them to family and friends. They work very hard and customer satisfaction seems very high on their list of priorities.
All now installed the stoves look and perform great! Thank you to all Stovefitters Warehouse!

Quality product, great advice and delivered quickly

I ordered a few different twin-wall components for my installation after speaking with one of the guys at The Stove Fitter's Warehouse for advice. After a run through of my installation queries over the phone, I received great advice and help with my order.

Stack replacement kit

I used The Stove Fitters Warehouse to help with everything needed for an existing system that has just had the chimney stack removed (side roof after a loft conversion)
All items that were delivered were better quality than expected, nice thick metal and not flimsy at all. I opted for the additional over brackets to give it strength and it worked a treat giving me a self supporting 2.5m section flue above the roofline. Highly recommended. Thanks

Twin-wall stove pipe and fittings

We recently purchased the necessary bits and pieces to install a wood burner in our static caravan to prevent us from having another freezing winter whilst we renovate a house. The twin wall was obviously a major factor in the installation and having ordered the things we thought we needed we were then emailed by Stovefitters to say we had missed a couple of key fitting bands necessary for the installation of the twin wall section. This was vital to the fitting and had we not be advised we needed them we would have been left with an open roof and unable to complete the fit in one go. The service from stove fitters has been exceptional from the online advice made available, the easy ordering process, the followup email with yet more great advice, the phone call to add other things that we needed, to the fast delivery. We really couldn't recommend them highly enough. To top it all we are now snug in our caravan for winter!

Great service and good product.

The guys at Stove Fitters were really helpful with technical advice and the twin wall arrived promptly and is great quality.
