How many degrees does the radiator need?

There is no uniform requirement for water temperature of radiators in China. There are usually three situations: inlet temperature 95, outlet temperature 70; Water inlet temperature 75, water outlet temperature 57; Water inlet temperature 55, water outlet temperature 45.

In 2002, the country formulated the Indoor Air Quality Standard GB/T 18883-2002, which stipulated that the heating standard in winter was 16 ~ 24℃, and the indoor temperature that reached the standard was indoor comfort temperature. For example, the indoor heating temperature in a residential area is 18℃, and the design specifications for heating in most residential areas are: inlet water 80℃, return water 60℃, room temperature 18℃. The minimum standard of water inflow should be no less than 50℃.

Generally, radiators are installed in accordance with this specification. When the water temperature is low, the heat dissipation of the radiator will drop, and the heat load required indoors will not be reached, and the indoor temperature will not rise.

Treatment measures for not being hot at home in the early stage of heating;

At the beginning of heating, when the indoor heating is not hot, the radiator is not half hot or there is water noise in the radiator, it is necessary to open the manual exhaust valve at the end of the radiator to eliminate the air accumulated in the radiator, and close the exhaust valve after the water overflows.

In the process of heating, if the heating pipe or radiator is found to be leaking, the control valve or water supply main valve of the faulty pipe section should be closed and returned to the house, and the maintenance personnel of the property company should be notified in time or the heating company should be called for repair.

After debugging, the valves on the heating pipeline shall not be closed and opened at will. Keep a good heat dissipation space on and around the radiator, do not pile up sundries, and do not seal the radiator during decoration, so as not to affect the heating quality.
