How Do Radiator Heaters Work?

Radiators draw heat from water or steam and use that heat to warm up surrounding air. By doing this they can effectively be used to heat up a room.

Radiators are made from aluminum because it’s an excellent conductor of heat. Hot water travels through the radiator and the exterior fins naturally heat up over time. As those fins heat up, the surrounding air heats up as well.

Radiators are one of the oldest and most effective ways of heating a home. They’re still used in buildings all over the world today and there are only a few options more effective being relied on. Radiators are still desirable because of their simplicity and their ability to heat a space evenly and comfortably. In order to get the most out of your radiator heating system, or decide if radiators are the right option for you, it’s important to understand how they work.

Radiator Heat Transfer

If you’ve ever looked at a heat radiator you’ll notice that most of them are heavily folded. They have a bunch of creases and are made of some type of metal like cast iron. The creases or folds are designed to increase their surface area so that the metal comes into contact with more air.

Natural Air Circulation

It’s uncommon for a home heating radiator to have any sort of blower because it simply isn’t needed. As the air surrounding the radiator heats up it rises up and out of the way and new cooler air comes in to take its place. A rotational current of air forms around the radiator causing all the air of the room to slowly heat up.

How do steam radiators work?

Steam radiators are one of the oldest types of radiators and are still commonly used today. Steam radiators are connected to a boiler given the task of heating up water. The boiler heats water until it forms into steam. The steam then travels up through the vertical pipe to the radiator where the thermal energy is given off through the fins. As the heat is lost from the steam, it slowly begins to turn back into water. Eventually the steam becomes water and flows back down into the boiler for heating once again.

The cycle of heating and cooling repeats over and over again in order to spread heat to the rest of the home.
