Convection.
A chimney heat exchanger system efficiently transfers heat from flue gases to water for heating by using metal tubes or coils that run through the chimney. As the hot flue gases pass through the chimney, they heat up the metal tubes, which in turn heat the water circulating through them. This process allows for the transfer of heat from the flue gases to the water, increasing the overall efficiency of the heating system.
Hot air spinning upwards is called convection. This occurs when warmer air rises and cooler air sinks, creating a circular motion that transfers heat energy from one area to another. Convection is a natural process that helps distribute heat in the atmosphere and oceans.
If you have something that is not actually in the process of reacting and is getting hotter or colder, heat is being transferred. (Though technically, heat is always being transferred.)
The same process is used to lift a hot air balloon off the ground. Everything on the earth is under atmospheric pressure. Think of that as the weight of everything above you weighing down. Even air has some weight. When air (a gas) gets warmer, such as in the fireplace or in the burner of the balloon, then the molecules are excited and they move farther apart from each other. This causes the air to weigh less (become less dense). When the air weighs less, then it rises. The chimney is built right next to the fire to give a place for the air to rise. The smoke particles are carried away and up the chimney along with the rising air.

To start off, a Chimney Liner is a clay ceramic, or metal conduit installed inside of a chimney. The main purpose of a Chimney Liner is to contain the combustion products, direct them to the outside atmosphere, and to overall protect the chimney walls from heat and corrosion. You need a Chimney Liner because the flue gases are acidic and will literally eat away at the mortar joints from inside the chimney. As the mortar joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into the living areas of the home.

This process is known as convection.

A heat sink is a device or fixture that transfers heat from a component, such as the CPU or processor, it acts like a radiator in which it transfers the heat into the air. Aluminum is shaped by the extrusion process which is like squeezing tooth paste out of a tube.
Conduction is the main process that transfers thermal energy through the metal saucepan. Heat is transferred from the heat source to the metal pan through direct contact of particles within the material.
