Used the flue design service to enable us to design and construct the detail around the fire surround (nothing worse than being in the dark on detail). Stove and twin wall arrived as scheduled and only needed checking to familairise ourselves with the parts, which took about 10 min. To our obvious relief when the stove and flue system were installed they fitted perfectly and because of the preparation we were able to make, using the flue design service, it was completed in under a day. Fired up the wood burner on the following weekend and we are extremely pleased with the Firewire Curve 450 in terms of looks and performance. The room which was hardly used is now the most popular since the installation and I actually emailed my friends and family with a text image of the stove when it was lit and believe me I never usually get that excited!
