INDEPENDENT WATER SUPPLY SYSTEM Russian patent published in 2009 - IPC F24D3/00 

FIELD: heating systems.

SUBSTANCE: independent water supply system includes hot water tank which is equipped at least with one heat generator, hot water supply and return pipelines connected to the tank, and pipeline used for being connected to cold water source, the first circulation pump installed in hot water supply pipeline, shutoff valves and water gauge device installed in the tank and electrically connected to the appropriate shutoff valve installed at the tank inlet in the main pipeline used for being connected to cold water source. In addition, system includes cold water supply pipeline, pump and pressure control; at that, as shutoff valves installed at the tank inlet, water supply system includes on-off hydraulic valve. Pump is installed in the pipeline used for being connected to cold water source; at that, at the pump outlet this pipeline is hydraulically connected to cold water supply pipeline and has the possibility of being connected to the tank through the above on-off hydraulic valve in one of its positions. Pressure control is installed in hot water return pipeline; at that, hot water supply pipeline at the outlet of the first circulation pump through the pipeline which is additionally introduced, in which there installed are appropriate shutoff valves hydraulically connected to pressure control inlet, and outlet of the latter is connected to tank. At that, supply pipelines of hot and cold water accordingly, hot water return pipeline and pipeline used for being connected to cold water source, have quick-disconnect connections to be connected to external pipelines.

EFFECT: developing independent transportable heat supply system meant for hot and cold water supply and heating, and providing unused water economy.
