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

Please read this page first.

  1. Follow the link “Proceed to add property dimensions” to choose your chimney type and enter your property details into our Clickflue system.

  2. Upload any photos or drawings if you wish.

  3. We design your chimney, list required parts, and provide a quote. Julian or Ray will email if needed.

  4. You decide whether to purchase.

The 6-minute video below explains chimney design basics and helps you check if your stove location is feasible.

If you struggle with the form, email info@stovefitterswarehouse.co.uk with any details or a sketch. Julian or Ray can input the information and produce a design for you — free of charge.

Designed your own system? Send your drawings to info@stovefitterswarehouse.co.uk and we’ll check them over for free.
