Bosch Tronic 8000 T ES 100-5E 0 WIR-B (7736503148)

Heating elements - more, thermal insulation - thicker

By design, Bosch Tronic 8000 T ES 100-5E 0 WIR-B does not differ much from other electric boilers belonging to the “above average” class. But some details and elements deserve attention. For example, the layer of polyurethane insulation that "envelops" a 96-liter steel tank on all sides is 32 mm thick - 5 - 7 mm more than most competitors. And the inner surface of the storage tank is covered with glass ceramics (the manufacturer believes that it is more hygienic and better protects the metal than traditional enamel). Two "dry" heating elements with a total capacity of 2000 watts are responsible for heating the water in the tank. Each of them is a copper heating element, which is located inside a steel "glass" and therefore does not come into direct contact with water. This design increases the life of the heating element, eliminates the "hiss" and "buzz" during water heating (although relay clicks will still be audible) and reduces the amount of scale in the tank.

Adjustable to within a couple of degrees

This boiler is electronically controlled. The dashboard is very modest in terms of functionality. It has an LED indicator for the operation of the water heater, a button for turning the appliance on and off, buttons for adjusting the temperature and a small LED display for displaying it. Using the buttons, you can set the temperature in the range from 8 ° C to 70 ° C. A mode with water heating to such a small value as 8 ° C is needed, strictly speaking, exclusively for frost protection, so that the water in the boiler installed in a room that is not heated and not used in winter (for example, in a country house or in a summer kitchen ) did not turn into ice. The water heater is equipped with a very precise electronic thermostat. Thanks to him, the temperature of the water in the tank will never differ from the value set by the user by more than 1 - 3 degrees.

Features and nuances

The display not only displays the temperature, but also displays information from the built-in self-diagnosis system of the device in the form of error codes. However, the instruction manual assures that the Bosch Tronic 8000 T ES 100-5E 0 WIR-B boiler has only two types of errors: a short circuit and failure of the temperature sensor. Although the design of the water heater allows it to be mounted to the wall in a vertical and horizontal position, it is not possible to rotate the LED display by 90°. How it is supposed to adjust the temperature is a mystery (users who choose the horizontal mounting method can rack their brains over it themselves).
