Here are questions to refresh what you had learnt:
1. Where are steam heating systems (SHS) can be found?
2. Where do SHS commonly use?
3. Without required pump, how does SHS distribute and provide heat?
4. What is the functions of a loose lid when contained water applied with thermal energy?
5. What happened to internal pressure as thermal energy applied to a sealed container?
6. How do water molecules react when both of the pressure and temperature are increasing?
7. When water transformers from liquid to steam/vapor, how many times does it expand?
8. Explain how 2-pipe steam heating system work.
9. What is steam hammering?
10. What needs to be installed to prevent rupture or steam hammering?

Areas of application here in Germany for steam heating systems.
Fields of application
Steam heating is hardly used in office and private buildings. It is mainly used in larger buildings such as exhibition halls or warehouses. Here it is characterized by low operating costs. Another advantage is that it heats up large rooms quickly. The poor controllability and the high space requirement are disadvantages that make steam heating unsuitable for conventional private houses.
The use of a steam heating system is particularly useful where process steam is generated. This is the case, for example, in industrial laundries or commercial kitchens. In this way, the steam that is generated anyway can be used for heating.

I would maintain that the pressure in the system plays no role in the circulation of steam and condensate. Rather its the change in density and the resulting convection current. The steam is light and rises up to the radiator (always situated ABOVE the boiler. The condensate is heavy and naturally drains back to the boiler. The system pressure dictates the temperature of the steam and therefore that of the radiator.

Can you do a comparison between a water evaporation air conditioners (swamp coolers, a change in state air conditioner (traditional air conditioner) and heat pumps and centralized chillers. I sure love my air conditioner during the short but very hot western Canadian summers. Looking at buying a heat pump to replace my AC and supplement my winter heating.

Hello and thank you for the very informative videos. Im now to steam heating and we just purchased a building with a steam boiler. Im trying to learn more about the older looking thermostats in each room that have a copper tube running into and out of it:
How does it works and how to replace them.

Why in the name of #%% do we not see induction technology; as heat souce? heatbuildings! Even a simple electric oil filled home portable space heater could use this technology! Making it possible to heat a building for a fraction of gas, coal, oil ect?

Lets suppose that we supply the radiator with steam 0. 5 barg. From steam tables we see that steam temperature is 112 C (233 F. Dont you think that this radiator is going to cause severe burnings to anyone who will touch it accidentally?

Hey The Engineering Mindset, how about video comparing steam heating and conventional hot water heating. I live in europe, it's first time I hear about steam heating so I'm curious about differences.

In my opinion steam heat is great for residential use. Although it takes a while for the radiators to get hot they retain the heat for a long time and your house does not get dry like with hot air heat

So if too many people shut off their radiator valves I assume the boiler would start to overpressurize? I assume the boilers have emergency pressure pressure relief valves so they don't just blow up.

Can you guys do vacuum pumps, boiler feeds and other boiler auxiliary equipment? Ive been referring a lot of new guys to watch these videos as they are super informative for an operating engineer!

As someone who lives in a tropical country, I never understood how heating systems work when watching western tv series. Thanks for this very informative video!

Thank you for continuing to share and educate those of us in the unwashed masses. You do an excellent job explaining whatever topic the video is on.

Thanks for another simplified and well explained video.
Question: Do you have to add water to this system at any time to compensate for losses?

Omg thank you! The example you gave with heating and covering the pot made it so easy to understand. Even my dumb monkey brain got the concept down!

So for example like in big nyc apartments that have the pipes running through the room lol. Do each tenant pay for the heater?

Hello, thank you. How much do you think can cost for the equipment only for heating the building (15m x 40m x 4m) up to 60 celsius?
