Abstract

The boiler is applicable in domestic and industrial heating installations with a timer, distinguishing between the day and night tariff for electricity. The boiler quickly heats the liquid to the temperature required by the consumer, does not consume energy during periods other than the periods specified for heating, whenever a liquid is drawn from it with a temperature higher than that needed by the consumer, and can release heat directly to the flow of the liquid flowing out of it. It consists of a control device (18), a heat insulated vessel for liquid (1) with electric heaters (5) and temperature sensors (6 and 7) in the lower part, covered with a cover (3), connected with the upper part of the space of a vessel (1) through a pipe (4). Through the bottom of the vessel (1), located under the cover (3), an outlet pipe (8) passes. The cold liquid flows in through the inlet of a filter (9), connected with the inlet (10) of a distributing device (11), the outlet (13) of which at valve (16), which is normally opened, is connected with the space under the cover (3), while its inlets-outlets (14) through pipes (17) are connected with the lower part of the space of the vessel (1), on the side of the cover (3).
