We have been designing twin-wall chimney systems since 2007 (in winter we will often do 10-20 designs a week) and have one person who specialises in this one task. We use our own twin-wall design software (we created it from scratch) which is accurate to within millimetres. We strive to make the procedure as simple & stress-free as possible.

Our software is able to design for flat or sloped roofs, internal or external chimneys and gable ends.

The design process

1. Please read all of this page.

2. If you wish for us to design your chimney please follow the link below "Proceed to add property dimensions, where you will be guided through the process of choosing your desired chimney type and adding your property type and dimensions so we can then input this into our Clickflue software package.

3. During that process you will be able to upload any images or drawings (if you wish).

4. We design your chimney and list all the parts required and provide a quote. Julian or Ray will communicate with you via email if required.

5. You choose whether to purchase.

The video below "How to design a twin wall chimney for a wood burner"  is just six minutes long and may assist you if you are unsure whether your chosen stove location is feasible. The video also explains simple chimney design constraints.

If you have any problems using or understanding the "add proper dimensions" process please email info@stovefitterswarehouse.co.uk. Add any information you feel is relevant. Either Julian or Ray will get straight back to you. With the correct information or a good sketch we can add all the information for you and get a design sorted. All free of charge.

The videos on this page may tempt you into designing your own  chimney system. Feel free to send any drawings to info@stovefitterswarehouse.co.uk and Julian or Ray will check them over free of charge.

Excellent Customer Service, Thoroughly Recommended. (Order no: 20764)

Having spent most of the previous year researching a small stove for our garden log cabin it was such a relief to find Stovefitters Warehouse, just wish I found them a lot sooner. Their website is easy to navigate and they have a wealth of information and videos available. We had previously been quoted rediculous prices to install a stove but after studying Stovefitters info we decided to do this ourselves. Communication was very efficient, by text and phone calls, and all our queries and questions were answered. So good to have 'real people' to contact. We orderred the Salamander Hobbit stove and the shed fitting kit. The stove is awesome and kicks out a lot of heat for its size, we returned a couple of items from the fitting kit and orderred others, all straight forward and simple. We have recommended Stovefitters to several friends already and will continue to do so. Would definitely use them again, excellent company to deal with.

Stovefitters have been very helpful and informative throughout the process of buying a good stove then helping with the flue design and then supply of materials. Their professionalism has been excellent and attentive and they have sent high quality parts and supplied information as and when required.
I can’t recommend highly enough. They’ve been great

Virgin fire fitter ,

As a first time fitter of a woodburner stovefitters warehouse were invaluable in the process, scanning through endless sites for twin wall can merge into one big blur. The information and detail provided on your website was unmatched anywhere else and the quality of the materials were excellent , when there was something I was unsure of a simple message on the chat page cleared it up . Delivery was prompt and on time all in all delighted with the service provided
