Hi, Can anyone give me some advice please?
I have a mira 415 running off a Worcester 24 combi, both are approximately 5 yrs old and the boiler is well serviced by British Gas.
The problem I have is that the temperature of the water goes from either freezing cold to scalding hot in a cycle of probably 30-50 seconds. No amount of adjustment of the control helps me. any ideas anyone?
Also what would I need to keep the pressure/temperature constant if someone flushed the toilet or used another tap?
any advice would be gratefully received. Thank you
