Expansion tank 50litr Mehrafrooz

The open-air source is, as can be seen from the illustration, a reservoir that is connected to the open air and exterior air pressure is applied to the surface. To prevent water overflow and to regulate system pressure, an open expansion source is installed above the top radiator (generally on the roof). Open expansion sources are used for low pressure central heating systems with a maximum temperature of 180 degrees Fahrenheit. How Open Source Source Works As noted above, as the volume of water circulating in the central heating system increases as the temperature rises, the water level in the open expansion spring rises and the static pressure equals the height of the source relative to the boiler. This pressure applies to all the water in the thermal installation system and causes the water to rise from the pipes of the transmission system. For this reason, open source should always be installed at a height (at least 2 meters) above the highest radiator. The pressure range of these sources depends on the height of the open source installation relative to the boiler. The open expansion source also controls the amount of water in the cycle through the mains water pipe and by the float therein, so that in the event of any leakage in the installation cycle that reduces the volume of water in the expansion source, Adding municipal water as much as the output of the cycle, the amount of cycle water remains constant. How to install open source expansion The connection of the open expansion source to the central heating system is accomplished through two circular pipes to the circulating water transfer system. The reason for installing a round pipe to these sources is the circulation of hot water in these tanks. Because open source water is exposed to cold winter weather, there is a possibility of freezing of water in the reservoir and preventing hot pot circulation in the reservoir. In addition to these two circulating pipes, open expansion springs are also connected to municipal water to compensate for the water shortage required by a floating valve.
