If the top of a radiator is cool and the bottom is warm, that is air, and bleeding it is a five minute job.

Turn the heating off and let everything cool. Start with the radiator furthest from the boiler, or downstairs if you have two floors. Open the bleed valve at the top corner a quarter turn with the key, hold a cloth under it, and close it as soon as water comes instead of air.

Then check the boiler pressure. Letting air out drops it, and if it falls below about one bar you will need to top up before the heating will fire properly.

If it needs doing every few weeks, air is getting in from somewhere and that is worth investigating.

A single radiator staying cold while the rest of the house is fine is usually one of three things, and two of them you can check yourself.

First, the valve. Thermostatic valves seize, particularly over summer when they sit untouched. Take the head off and press the pin underneath. If it does not spring back, that is your fault and a new head is inexpensive.

Second, air, if it is cold at the top only. Bleed it.

Third, balancing. If that radiator is nearest the boiler it can actually be starved because the others are taking the flow, or the lockshield at the far end is closed too far.

If none of that shifts it, the radiator itself may be blocked with sludge.

Warm downstairs and cold upstairs almost always means air, and it collects at the highest point of the system.

Bleed the upstairs radiators first, starting with the one furthest from the boiler. Check the pressure afterwards and top up if it has dropped below about one bar.

If they still stay cold, look at the pump. An older pump losing performance can push water round the ground floor but not lift it reliably to the first floor, and that shows up exactly this way.

The reverse pattern, cold downstairs and warm upstairs, points at sludge instead, since debris settles low in the system.

If your boiler sounds like a kettle coming to the boil, that noise has a name and a cause.

It is called kettling. Scale or sludge has built up on the heat exchanger, water gets trapped against a hot surface, and it flashes to steam. The banging and rumbling is that steam collapsing.

It is not immediately dangerous but it is doing damage. The heat exchanger is the most expensive part of the boiler and kettling shortens its life considerably. In hard water areas it comes from scale, everywhere else it is usually system sludge.

Caught early it is a clean and a filter. Left a year or two it can be a new boiler. Worth acting on the noise rather than getting used to it.
