How long does a radiator last?

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.
