**Typical lifespan: 15–100 yr**

A wall-mounted heat emitter fed with hot water from a boiler, transferring heat mostly by convection.

> Victorian cast-iron radiators are still in service; pressed-steel panels corrode from the inside in 15-25 years.

## How that compares

*Radiator against things of a similar time.*

- Radiator: 15–100 yr
- Polar bear: 20–32 yr
- Giraffe: 20–28 yr
- Grizzly bear: 20–35 yr
- Bathtub: 15–50 yr
- Elevator: 20–40 yr
- Tractor: 15–50 yr
- Window: 15–40 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| Period | How many you would buy |
| --- | --- |
| Per year | 0.04 replacements |
| Over 10 years | 1 of them |
| Over a 30-year mortgage | 1.2 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
