Water-side connection of a central-heating boiler

摘要

The water-side connection of a central-heating boiler is to be designed in such a way that condensate formation owing to inflowing, cool return water is avoided. For this purpose, the return connection (9) leads into the upper, front region of the heating boiler, and to be precise in such a way that it is surrounded, with a forward-pointing extension (10), on all sides by a shaft (11) with a horizontal throughflow. Owing to the injection action, hot flow water is sucked through the shaft. A mixture of cool return water and hot flow water comes into contact with the boiler surfaces, with the result that condensate formation is prevented. <IMAGE>
