What are hypocausts?

Hypocausts are heating systems used by people long ago, like a warm floor that helps keep rooms cozy.

Imagine you're playing on the floor in your living room, and it feels like it’s been warmed up just for you. That's kind of what hypocausts do, they heat up the floor so the whole room gets warmer too.

Hypocausts work by using hot air from a fire below the floor. Think of it like having a little fire underneath your feet, but instead of burning your toes, it warms up the whole room.

Inside the walls or under the floor, there are special spaces called ducts, and hot air moves through them like in a tunnel. This warm air goes up into the room, just like when you blow on your hands to make them warmer!

People used hypocausts in big buildings like bathhouses and homes long ago. It’s like having a built-in heater that keeps everyone comfortable, even during cold days outside. Hypocausts are heating systems used by people long ago, like a warm floor that helps keep rooms cozy.
