The patented Xaralyn bio ethanol burners with ceramic core carry a lifelong production-warranty. This means that we give a 30 year production-warranty to the first owner of these burners. During this period Xaralyn guarantees production and/or material defects. Faulty usage of the product does not fall under the warranty. In case a part needs to be replaced, due to loss or damaging, it can be ordered with us.
