    Hi was just looking at the select range from hwos particularly the motorized valves and circulating pumps. I service and repair oil boilers but don't do any plumbing work as I'm not a plumber but I have done oftec 101, have a fga etc. What I'd like to ask is can you replace a 5mtr head circulating pump with a 6mtr head, or would that be to powerful or with these newer pumps can they adjust and find their own speed.

    You may find that say the existing pump is set on 3 the new pump will need to be set on 1 or 2. Should say in the instructions.
