The Stove Wizard began as a father-and-daughter venture in a North Wales garage in 2010 — hand-packing ceramic coals with care, grit and a bit of stubborn spark. Over the years, we’ve grown into a nationally recognised name in fireplace styling — trusted by home renovators, boutique designers and major film sets alike. Every item we sell reflects our values: practical craftsmanship, long-lasting quality, and a personal touch you won’t find from mass-manufactured brands. We’re still proudly family-run, still flame-obsessed, and still packing every order like it’s our very first.

If being used with a Bio Ethanol fire — as with ALL bio ethanol fires — you CANNOT put anything in the flame, or it will no longer be a clean burn. These must be placed around the fuel reservoir. If they are placed over the flame you may get black smoke.
Our fire accessories are trusted by set designers at BBC, Netflix, HBO, ITV, Prime Video, and Warner Bros.

We do not sell coals, pebbles or logs for any individual fires as each company has their own spares usually available. Our coals, pebbles and logs are direct from a UK RCF manufacturer and often are the exact product that would have been supplied with the fire, however due to the warranty offered by the fire manufacturers they will only recommend spares purchased directly from themselves. The products on offer are not designed to fit specific fires, although they have been found to be suitable for a wide range of gas fires. The Stove Wizard is not responsible for any loss of warranty caused by their use. We take no responsibility for any damage to the fire that may be caused by improper installation of our products.
