water warm, not hot?

It may be that your mixer valve is furred up with lime - it is a common problem on the Myra shower valves. Take the shower valve apart (it is a pain) and use some de-scaler on the spring/mixer valve. leave it to descale for specified time then reassemble it. It should work fine, but if it is a hard water problem it will happen again. The best advice if this is the case is to change the complete shower unit - because the problem will keep coming back.
