my combi boilers got too much water pressure hence the shower starts off hot then works its way cold
can i restrict the water pressure going to the boiler or is there some adjustment in the shower mixer valve assy
shower mira 415
boiler worchester 924
it sounds as though your thermostatic cartridge inside your mira is playing up. The 415 is made for high pressure systems so it has nothing to do with your boiler.A new cartridge will cost about £40 but if the shower is under 2 years old it will be covered by mira and they should replace it for free

sounds like a prob with your shower. boiler and shower should work together really well. if, when you have the shower on the boiler turns itself on and off then its a prob with the boiler, possibly scale or sludge
