Okay, kiddo, do you know how sometimes when it's cold outside, we put on a warm jacket to stay cozy? Well, imagine if you could do that for an outdoor space like a patio or backyard. That's exactly what a patio heater does!
Basically, it's a special machine that you can set up outside to help keep you warm when it's chilly. It uses either propane gas or electricity to create heat, kinda like your stove or oven does in the kitchen.
The patio heater looks kinda like a tall lamp with a metal head on top. That metal part is where the heat comes out, which can keep a small area warm enough for people to hang out and enjoy the fresh air without shivering.
But just like with anything that gets hot, safety is super important. So if you ever see a patio heater, make sure you ask a grown-up to carefully set it up and operate it. And that way, you can enjoy spending time outside even when it's cold!
