Had a radiator removed by plumber and since then the shower runs hot and then very cold then very hot again. Before the radiator was removed the shower was even temperature all the time. Worcester Bosch 28iJunior boiler was installed only 2 and a half years ago. Pressure on boiler is 1 and a half. Any ideas what has gone wrong?
