Cheers, did what you suggested. Pressure stayed same all night. Must be the dhw heat ex. as I thought. Thanks for your input. Cheers.

Thanks, will try that tonight.

Yep, it's an internal filling loop. Thanks.

Hi, I've got a worcester 28cdi, and the pressure keeps rising. I keep draining some water out of a radiator, to take the pressure back down to 1 bar. Overnight, or during the day, it then rises back up to around 2.5 bar. Is the heat exchanger the problem? Is this something I can buy and fit...
