Why is my hot water not working but radiators are?

Why is my hot water heater not getting hot?

How does a hot tap work on a radiator?
You simply have to run the hot tap at a slower rate than you normally would. Diverter valves switch heat between the hot water and the central heating. When you turn your hot tap on, the diverter valve temporarily shuts off the water supply for your central heating, and when you turn the tap off, the valve reopens and feeds your radiators.
Why are my radiators always on with no hot water?
If your radiators are always on but you have no hot water The valve has almost certainly stuck in the heating position. The cylinder thermostat is calling for hot water from the boiler, but the stuck valve means it can only go through the radiators.
