CZ267292A3 - Heat-saving water heater with a reservoir - Google Patents

Abstract

The purpose of the invention is to save heat energy when heating water. This purpose is achieved by an economical electric heater water, which consists of at least one electric heating a plate (1) with a metal layer (2) to which it is pressed on both sides a helically coiled tube (3) with water inlet (4) a with water drainage (5) to hopper (6) with drain pipe (7) and everything is protected by a thermally insulating layer (8) with a thermostat (9) and sheath (10) with indicator light (11)

Description

Energy-saving electric water heater with storage tank.

Vinegar techniques of water heating in the home.

BACKGROUND OF THE INVENTION.

Nowadays, electric heaters with heating coils radiating with heat and unused light radiation are used for domestic water heating. This advantage is recently solved by instantaneous water heaters consisting of at least one electric heating plate to which are screwed twisted pipes with water inlet and outlet from both sides. However, these protected by a thermal insulation layer have the disadvantage that they do not allow the heating of larger amounts of water and that the pipe must be metal for uneven heating.

SUMMARY OF THE INVENTION The above-mentioned disadvantages eliminate the economical electric water heater with a reservoir according to the invention, which consists in that it consists of two electric heating plates provided with a metal layer to which a screw-shaped coiled pipe with inlet and outlet water is pressed the hot water tank is placed in contact and everything is protected by a thermally insulating layer with a thermostat, a jacket with an indicator light and a supply conductor. The advantages of an economical storage tank heater are not only energy savings, since the electric heating plates do not contain resistive spirals, but the electrically conductive carbon layer converts electricity to the highest degree and the twisted pipes transfer heat to the metal reservoir. There, keeping the heated water at an optimum height, but also in that of the metal layer of the heating plates, distributes heat over the entire surface and thus allows the use of plastic nraot pipes, for example polyethylene, polypropylene, polybutene.
