摘要： The disclosure relates to a method for the manufacture of an interiorly insulated tank with an outer casing (1) and a port (5), comprising the steps that: a sack (3) of a flexible, non-tensible and fluid-tight material is wholly or partly inserted in the outer casing (1) so far that the sack, in the filled state, is substantially equidistant to the inside of the outer casing (1), that the end of the sack (3) facing away from the port (5) is positionally fixed in the outer casing (1) and that the space between the sack (3) and the outer casing is filled with a foam-forming insulating material (8), which is allowed to set whereafter the sack is removed.

摘要： The disclosure relates to a water heater with an outer shell or casing (1) with interior insulation (2) and an elastic container (6) for water interiorly therein. At normal operational pressure, the container (6) substantially fills out the space in the insulation (2). The elasticity in the container (6) is sufficient in order, on opening of a faucet in the water system to which the water heater is connected, to expel a volume of water so that the volume of the container, compared with a completely filled container, is reduced by at least 8 %.
