Plug provided with air hole is tightly inserted into neck of casing. Plug is fastened by screwed cap provided with air hole which is not aligned with hole in plug. Method of detecting of slow leaking of water from heating system is based upon the fact that temperature graph of the system is built in summer without heating. For the purpose values of water level in level-metering pipe of the tank at steady temperature are put along abscissa and values room temperature are put along ordinate; received calibrated curve is subject to calibration. The graph is taken as averaged temperature calibration graph and steady values of outside temperature are drawn above corresponding values of level. When taking subsequent measurements, the averaged temperature is determined again and if the value of level get lower it is assumed that water loss takes place because of leakage or evaporation of water caused by disturbance in leak-proofness of the air bag.
EFFECT: simplified design of tank; better degree of protection of membrane.
