Hi all,
Can anyone give me some advice as to why when I switch central heating to water only in summer, it doesn't take long for the sounds of rushing water in and around the circulation pump inside the airing cupboard. If I call for radiator heating and the 3 way valve goes to mid position, all goes quiet with the system. The pump is an old WSP GOLD fitted in 1996 (year of house build) and this when circulating the full system is fairly quiet apart from a bit of humming heard.
I have recently cleared a blockage from F&E tank in loft which was the 15mm feed pipe to the heating system. I have also circulated FERNOX DS40 for a week and cleared a lot of sludge from the system. All radiators now heat up well, however, when calling for hot water only and 3 way valve closes to the radiators, the noise is loud and annoying. It feels like it might be damaging the pump running like this. Does any have any solutions to water only heating (quietly) Thanks in advance.
