<p>The washing water tank is particularly for a district-heating system. It comprises a corrosion-resistant vessel with bottom inlet and top outlet, also one or more heat-exchangers through which heating water flows. The inlet (2) to the vessel (1) is above the level of the heat exchanger (13,17), through which flow takes place from bottom to top. From the bottom (9) of the vessel a circulation pipe (10) with pump (12) leads to the top outlet (5). The pump, and the valve (15) in the inlet pipe to the heat exchanger, can be controlled by a thermostat (20) mounted above the inlet union (2).</p> |
