Ferroli Combi Boiler

[JeniPeni]

The water in our shower (which runs from the combi boiler) is not staying at a constant temperature. The water will run hot, but then its cold water that sprays after a few minutes - and then back to hot again. We've turned the water off at the mains for about 20 mins to clear any airblocks, this done the trick for a day or so, but the problem is back again. Any suggestions? Thanks in advance.

Not sure if this helps. My water pressure is not that great. It affects the shower temp if anyone flushes the toilet, turns another tap on or garden hose,etc, while the shower is running. Only solution is for anyone to be aware that someone is in the shower.

ps even a drop in pressure at the water works can affect it.

thanks for that Johnny; its not the water pressure from washing machine etc, if someone is in the shower, the water still stays warm. Dodger, it looks like the same problems/solutions that you posted - thanks.
