inconsistant hot water supply

Hi,

Just moved into a new flat with an electramate water heating system. Im finding that I cant get enough hot water to run a bath and that showers are rarely hot and when they are dont stay hot for very long. Any help will be greatly appreciated.

thanks

I had this, you probably need to temperature sensor changed. I don't think this is an expensive part, but unless you know where to change it, then it can be hard...but it is literally unscrewing the original, put some seal around the new one, screwing it in and attaching the other end to the voltage boards....
