Have you checked your coolant level? If it's low that could be the easiest answer. However if you haven't kept up with reasonable coolant services I'd say your heater core is blocked. There's lots of DIY repair videos on YouTube. Here's one:

Could also be your blend door. Do a search on here about that. There is a ton of information about that. Very common problem for the X-Type.

If your coolant has been low you may also have an air trapped in the heater core.
