How hot is the water temperature of ordinary radiators?

If the water temperature of the radiator exceeds 30 degrees, the radiator will heat up.

Since the trial operation in the early morning of 20 18 1 1.5, the water temperature of the primary pipe network has reached 46.9 degrees, and the water temperature of the return water has also reached 43.6 degrees. The water supply temperature of some secondary pipe networks has also reached 34 degrees and is rising continuously, and the return water temperature has also reached 27 degrees.

Under normal circumstances, the radiators in the homes of residents whose water supply temperature exceeds 30 degrees will feel good. This means that the radiators in some communities already have a certain temperature. However, the public need not worry, because the temperature rise is a gradual process, not overnight. Different pipeline lines and different residential locations have different heating processes.

Extended data

Although the radiator starts to heat up at 30 degrees, the standard heat dissipation of the radiator needs to calculate the heat emitted per unit time under standard working conditions (Δ t = 64.5℃). In addition, radiator heating generally has three situations:

1, inlet temperature 95, outlet temperature 70;

2. Inlet water temperature 75 and outlet water temperature 57;

3. The inlet water temperature is 55 and the outlet water temperature is 45.

Preparation before heating

Check the indoor radiators one by one, and check whether the valves of the indoor heating system are in good condition and closed, and can only be opened during heating and water injection; Check whether the connection points of indoor heating system are in good condition to avoid running, running, dripping and leaking; Check whether there are hidden dangers that hinder heating repair; During heating and water injection, people should be kept in the user's home for observation; When the heating system is full of water, manually release air until the water comes.

Jining News Network -248 heat exchange stations have all been started. On the 8th, the heating in Dongcheng District of Jining warmed up in an all-round way.
