Why is 1 radiator in my house cold?

If your home has 2 floors you should begin bleeding the downstairs radiators first. It’s also advisable to start with the radiator which is furthest away from the boiler.

Do you need to bleed all radiators?

How do I know if my radiator is working?

Should radiators heat from top to bottom?
We all know that heat rises, so having a radiator that’s cooler at the bottom than the top might not seem like cause for alarm.
