Conditions for use of external cylinder units are justified, process parameters for their operation with indoor location are determined. Recommended residual level of cylinder filling (24-33%) for use of gas for needs of cooking and hot water supply is determined which allows to ensure continuous gas supply, forming consumers’ buffer stock in case of untimely delivery of cylinders due to organizational and technical reasons.
