Guys - have some hot water issues - when i turn the shower tap on which is a mixer, hot water comes out then the boiler gets to a certain temp then cuts out - as soon as the temp drops by like 6 - 7 degrees the boiler fires up again - so i get hot n cold water as the boiler is constantly igniting and stopping. Any help would be very well appreciated.

Thanks
