Why is Steam heating better then hot water heating?

Answer 1

The key is that "evaporation is a cooling process". Boiling water molecules use a small amount of energy to make the jump from a boiling pot into the atmosphere. That small amount of energy used reduces the molecule's average kinetic energy (another term for temperature). When you come out of a pool or a shower, you feel so much colder than when you were in the water. That's because air currents are causing the water to jump off your skin. As the water jumps into the atmosphere, you feel the subtle drop in temperature.

Answer 2

It's more effective. Condensing water vapor at the boiling point to liquid water at the boiling point releases over 5 times more heat energy than cooling liquid water from the boiling point all the way to the freezing point. (See answer below if you were talking about cooking.) ---- When you boil food, a lot of the nutrients leech out into the cooking water. Assuming you drain the food before you eat it, you lose those nutrients. When you steam food, most of the nutritional value of the food remains. There's also a difference in texture when you steam rather than boil, but that's really up to personal preference.

Answer 3

Steam heating is often preferred over hot water heating because it heats up quickly and efficiently due to the high heat capacity of steam. Steam also distributes heat evenly throughout a space and can be used in a variety of heating systems. Additionally, steam systems typically require less maintenance than hot water systems.

Answer 4

Boiling water is at 212 degrees F (100C), while steam can be far hotter than that.
