IMPROVING THE RELIABILITY OF AN ELECTRIC CENTRAL HEATING BOILER

Electric boiler, reliability, damage analysis, design. The article presented an accomplished project of an improved construction of an electric boiler in terms of reliability. The improvement was achieved by identifying the causes of failures in the previous boiler construction and introducing solutions that proved to be effective during exploitation. The damage analysis indicated two main causes of failures, which were pollution of boiler water and surges in the electricity network. Changes from the previous construction included the elimination of the most unreliable unit, changing the regulation system, and effectively systemically securing a group of semiconductor switches
