Abstract An apparatus for producing carbonated water. A first sealed pressure vessel is mounted within a second sealed pressure vessel having a cooling fluid surrounding the first pressure vessel. A cooling tube extends into the cooling fluid within the second pressure vessel and extends at least partially around the first pressure vessel. A recyclable coolant is circulated within the cooling tube and withdraws heat from the cooling fluid thereby cooling the first and second pressure vessels. A tube connected to a source of tap water extends through the first pressure vessel to an external outlet. A source of carbon dioxide is connected to a conduit opening into the first pressure vessel. The source of tap water is connected to another conduit opening into the first pressure vessel wherein the tap water and carbon dioxide are mixed forming carbonated water which may be withdrawn from the first pressure vessel via a tube connected to an external outlet. The pressure vessels are surrounded by insulation. Liquid drink concentrate is circulated through tubes extending through the insulation and are cooled by the pressure vessels.
