I had the same problem. The reason the water gets cold is that it runs through the water heating coil too fast, so it doesn't get hot. The mixing valve will add cold if your output is too hot, but if it's too cold the mixer can't help.

The cheap/easy solution, and this worked quite well for me, is to install a water-saving shower head. This will slow the flow through the heating coil in your boiler, and you should have good hot showers. If you want, try running the hot water very slowly while you shower. You should get hot water almost forever. If that works, get a new shower head so you can have a nice spray.
