The best way to chose a logburner IMHO

I chose this company based on the website, and it has been my go-to for the whole process of buying and installing up a log burner in my new home. From selecting the stove (such good advice and accurate - I can say that now after enjoying the ease of lighting, style, heat output and just loveliness of it - Dik Geurts Ivar 8kW logstore), to the ease of use for the design of the flue (and supply too), to feedback for queries (rapid, effective & personal) to the other bits; such as ease of adding new parts to the setup when the installer had to get round a roof truss - quick advice, easy order and fast delivery. When the courier mashed a part, the issue was rapidly and satisfactorily sorted. All round, a very good service and heartily recommended by me and the happy cat who is sitting in front of the fire now. Thank you all at the Stovefitters Warehouse. 2235

Very helpful

I bought my stove and flue from Stovefitter’s Warehouse and couldn’t be happier with the whole experience. The ordering process was fast and simple, and delivery was spot on – everything arrived well packaged and on time.

What really stood out though was how helpful they were with all my questions during the installation. I had a few queries as I was fitting it myself, and every time I got clear, friendly advice that made the job so much easier. Order number-22095

Fantastic service and great products – I wouldn’t hesitate to recommend them and will definitely use them again
