You can experience all sorts of problems with radiators: one radiator is not working; radiators are cold at the bottom, a radiator is leaking or none of the radiators are working. Such problems do not necessarily mean they need to replaced or indeed there is a problem with the radiator itself. To understand common radiator problems it is useful to understand how radiators work. Radiators are ‘wet’ heating systems, i.e. they are filled with water that has been heated by the boiler and circulated around the system. Heated water ‘flows’ from the boiler and then ‘returns’ back to it (hence system pipework is referred to a ‘flow’ and return’). Water and metal need to be prevented from reacting to each other to prevent problems. In this guide we give you expert advice on common radiator problems and solutions. We talk you through the likely causes and advise on repair or replacement.

This is mostly likely to be a problem with the boiler or the system pump. You may still be able to get hot water however. You will need to call a boiler repair engineer out to diagnose and repair.
Occasionally it can be a total blockage close to the boiler, but this is pretty rare.
