1. A flow-through heater, comprising:
a body having a first portion, a second portion defining a liquid-bearing tube, and a connecting web to connect the first and second portions, wherein the liquid-bearing tube has a flat area;
a heating element embedded in the first portion of the body; and
a thermostat mounted on the flat area of the liquid-bearing tube,
wherein the first portion of the body includes a material enlargement constituting an energy store on a side facing the liquid-bearing tube.
2. The flow-through heater according to claim 1 , wherein flow-through heater has a curved shape and the flat area is located on an inside area of the curved shaped flow-heater.
3. The flow-through heater according to claim 1 , wherein the liquid-bearing tube has a generally ring-shaped cross section with a uniform wall thickness and including two material enlargements comprising corner regions defining the flat area, the liquid-bearing tube being arranged adjacent to the flat area and the material enlargements.
4. The flow-through heater according to claim 1 , wherein the first portion, the liquid-bearing tube and the connecting web comprise an integral metal body.
5. The flow-through heater according to claim 4 , wherein the integral metal body comprises aluminum.
6. The flow-through heater according to claim 1 , wherein the material enlargement includes a flat area which extends parallel to the flat area on the liquid-bearing tube on which the thermostat is mounted.
7. The flow-through heater according to claim 6 wherein the flat area resulting from the material enlargement on the first portion and the flat area on the liquid-bearing tube, on which the thermostat is mounted, are arranged in a single plane.
