Narvi-cauldrons heat up large amounts of water at once. Once the water is warm, it will stay warm due to the fireproof vermiculite mass insulation even for 24 hours. The Narvi-cauldron is easy to use and the inner rustproof chamber pot can be detached for cleaning. Narvi 80 l cauldrons are available painted black or with a rustproof steel casing. The cauldrons have adjustable legs, which makes the installation easier.
