Iron is tempered by heating and sudden cooling.

So, now you're not alternately heating and cooling the metal, just the air.

I'm still heating the air every time and cooling the air every time.

And you're only getting power from the air that's heating at the same time, but you're wasting energy heating and cooling the metal.

like heating, cooling etc. and turn them into things that we avoid spending energy on.

A lot of heating, frictional heating.

Heating Coil

Just the heating and cooling from the time when the sun is up and the time when it's dark is unbelievable.

It was cooling down until about 1900 or so.

Cooling factor

So it's impressive, the vacuum of space, how much heating and cooling goes on out there and how much sun changes things.

It's cooling off.

He's cooling down.

The heating doesn't work.

His affection is cooling.

Instead of heating and cooling the whole cylinder, what about if you put a displacer inside a little thing that shuttles the air back and forth.

If you want to send you know, cold into the Midwest, you buy at pipeline capacity, you buy up options on heating and cooling degree days.

This school has no heating.

This heating system burns oil.

Next, there's the heating lever.

We measured the electricity used during air cooling in the same way as heating, and compared the old model air conditioner to the energy conservation (2001) model.

Which is known as cooling.

We have a good heating system.

This process is sometimes called cooling.

Instead of blowing a hurricane of chilled air through the stadium, we can use radiant cooling technologies, like a floor heating system where water pipes are embedded in the floor.

Our dorm's heating system isn't working properly.

Is there central heating in this building?

Is there central heating in this building?

We're just heating up the gaseous water.

So things are really, really heating up.

How do you turn on the heating?

Heating is a third of our energy consumption in Britain, and quite a lot of that is going into homes and other buildings, doing space heating and water heating.

The problem is the efficiency is one hundredth of one percent, because you're heating all the metal of the chamber and then cooling all the metal of the chamber each time.

Large areas would be uninhabitable without heating in the winter or air conditioning in the summer.

Disappeared into one of the cooling ducts.

It's a superconducting chip. No cooling needed.

I did without heating all through the winter.

The iron broke down due to over heating.

That's an open buggy. It doesn't have heating.

And that's the story with climate change heating.

Heating and hot water supply needs heat energy.

Mother! I've turned the cooling unit back on.

There are many more hours of cooling time than warming time, and day after day, this results in a cooling effect.

This principle is embodied by a radiant cooling system.

I'm taking the temperature of the canal outside, pumping it through the heat exchange mechanism, it's turning through these amazing sails on the roof, and that, in turn, is falling softly onto the people in the restaurant, cooling them, or heating them, as the need may be.
