Bigger Central Heating Pumps?

[Paul Levers]

I have recently extended my gas central heating system and now I experience radiator balancing problems that I never had before.
I am running a 5M head pump and was wondering if anyone has had experiance of up rating to a 6M head pump and the benifits that would bring?

Radiator balancing or balancing radiators goes by several titles. You'll also hear it called balancing the central heating system. Unless it's referring to a warm air central heating system or underfloor heating it all means the same thing, ensuring that all the radiators get equally hot. Ideally they will all get hot together, in about the same time. If all your radiators get hot pretty evenly you don't need to balance the heating system. Adjusting radiator valves can sometimes make them leak so don't turn them if you don't need to.
