I've had a Mira show for about 15 years, lately it's temp has been fluctuating, so I phoned the service desk, as I think it needs a new thermostatic control cartridge.

The lady on the service desk went through the causes, and rather than have me pay for a new cartridge, she said it might be the flow being too high, so the combi boiler can't heat the water quickly enough.

So a possible cure is to fit a restrictor.

So she sent one free of charge, just to see if it cures or helps.

Not bad customer service for a 15 year old product
