[Tommydee]

Could anyone tell what size water pump I need to run 10 radiators on my central heating system

Telephone your local plumbing centre they should be willing to help.

if you are using microbore (8mm) use a 15/60 as a very high resistance needs to be overcome

[stanleyman]

Ten rads in the average home with a standard bore system is well within the capacity of the smallest pump available.

All of the above answers are valid. Most manufacturers do a 15/50 and a 15/60. Frankly there's so little difference in cost you might as well use the bigger capacity pump and turn the head down using the three speed switch on the side.

Personally I reckon Grundfos are hide to beat and considering how dependent you are on the pump, its not worth scrimping for the few quid on a cheaper make. The Grundfos 15/50 and 15/60 are both about �50.
