How to turn off the heating?

How to turn off the heater: find a valve on the left side of the heater, make the scale point to 0, stop working, find a second valve on the right side of the radiator, and screw this valve clockwise to the end.

Heating can be divided into water heating and air heating. Usually radiator refers to water heating, that is, circulating water is heated by wall-hung boiler or boiler, and then linked to radiator through pipeline. Finally, the appropriate temperature is output through the radiator to form the indoor temperature difference, and finally, the whole indoor temperature is evenly increased through thermal circulation.

Warm air is hot air. As soon as the cold air comes in, it is heated into hot air by the radiator. Hot air rises and forms convection with indoor cold air. Cold air circulates near the heater and is heated into hot air. Hot air circulates in the house and the room is warm. The common heating facility in the north is water heating scheme. In fact, the earliest design demand mainly comes from the freezing of water pipes in winter in areas where the temperature will reach below 0℃, and the countermeasures arising from this phenomenon.

Selection skills of heating

1. Central heating users: Central heating is a clean and guaranteed heating method, and the heating group transports municipal heat to users' homes through pipelines. This method has low cost and relatively high safety performance. Pure aluminum radiator, die-cast aluminum radiator and aluminum alloy radiator should not be used, because aluminum is afraid of alkaline water. In order to protect steel boilers, heat exchange stations and pipelines, the pH of central heating is generally adjusted to10 ~12, which is alkaline.

2, low-temperature heating users, the water temperature does not exceed 85 degrees: hands can endure 2 seconds on the heating, the temperature is lower than 85 degrees. It is not suitable to use composite radiator, because composite radiator mostly heats indoor space through air convection. The water temperature is too low, the air convection speed is slow, and the heat dissipation effect is attenuated. Every time the water temperature decreases by 10 degrees, the heat dissipation effect will decrease by 40%, resulting in the situation that the heating feels very hot, but the room is always not hot.
