Central heating pump ?

[sinbad197]

Hi all,

This is possibly a stupid question but i was wondering if a modern combi boiler needs a seperate central heating pump ? Im doing the pipe work 22mm flow and return, its about 25metres total pipe run, 7 radiators, about 12kw total with a vaillant ecotec pro 28 boiler.

Would i need a seperate pump for this ?

Many thanks!
