this customer has had problems since day on with previous installer - i have been recommended to her. I have visited once and tried to balance the system - to no avail....
basicalled its a vented system worcestor 40cdi
originally there was one pump on the system.
conservatory rads werent getting hot so the installer has put a pump before them 4 rads - now they get piping hot even on low setting on pump and lockshields only slightly open....
but the rest of the house suffers - especially the rads on the downstairs circuit.
the downstairs circuit branches off straight after the pump.... the pipes get hot coming down wall (15mm but the installer has then run it under the floor to 3 rads 2 of which are big doubles) the rads do not get warm even though the pipes are coming down the wall.
I am due back there tomorrow - i am thinking maybe the 2 pumps are working against each other as in the first pump is creating the flow towards a tee, the second pump is then taking the flow towards the conservatory only?
im planning on going tomorrow to look at the pipework layout under the floor boards. also perhaps - take the 2nd pump off the system.
the house is big dont get me wrong - but theres only 4 bedrooms and maybe ten metres from pump to furthest rad - and 16 rads on system ?
was thinking maybe take the 15/50 off and put 15/60 on?
would the 2 pumps be acting against each other and dragging the flow towards one rad - i alwasy though the pump just pushes and not pull?
