Radiator
RAY-dee-ay-ter
Neutral Neutral
What it really means
The metal panel on the wall that gives out heat from the central heating. Most have a valve you can turn to control the heat in that room. If a radiator is cold at the top, it may need "bleeding" (releasing trapped air) — ask the landlord or look it up.
Chinese explanation
装在墙上、通过集中供暖散热的金属暖气片。多数带阀门，可调节该房间温度。如果暖气片上半部分不热，可能需要"放气"（排出积存空气）——可请房东处理或自己查教程。
Example conversation
A: My radiator’s only warm at the bottom.
B: It needs bleeding — there’s a little key for that valve at the top.
A：我的暖气片只有下半部分是热的。
B：需要放气——顶上的阀门有个专用小钥匙。
