Does anyone know of a stockist, supplier or manufacturer of soft ceramic tiles used in burners? Our supplier has cesed trading and ive looked everywhere for an alternative. The hard ceramic tile doesnt work – they melt. The only ones which can deliver the required heat output are those which crumble if you rub them. If we cant source these then its back to the drawing board for all of our twin boiler burners. Thanks, Nigel at PSB
