Why do general heating boilers choose hot water boilers instead of steam boilers?

The use of steam boiler heating is prone to the following problems:

1. The temperature rises too fast, the radiator suddenly cools and heats suddenly, and it is easy to leak water.

Second, the pressure rise is too fast, the radiator is easy to cause metal fatigue, the life is reduced, and it is easy to cause the radiator to burst.

3. The surface temperature of the radiator is too high, which is easy to burn people. At the same time, it also causes bad indoor weather conditions. The indoor dust is decomposed above the radiator, causing the wall above the radiator to turn black.

4. If the heating effect of the heating pipe is not good before the steam supply, it will cause water hammer when the steam is sent. The water in the radiator will form a water hammer under the impact of the steam, impact the radiator and the pipeline, and make a loud noise. At night, it will affect the rest. , also damage the radiator and pipes.

5. The water in the boiler is heated to absorb the heat released by the fuel, and the water molecules become steam and absorb a part of the heat, resulting in energy waste. To sum up, steam heating is not economical, and there are many hidden dangers, so in recent years, the use of steam boilers as heat sources has become less and less.
