Yeah I am just getting a bit confused about pumps thanks

From a text book
If we pump into an empty vessel, it would be easy for the pump to operate, the flow rate would be very large.
As the water became deeper in the vessel, the pump would find it harder to pump the water and the flow rate would become reduced.
Eventually the pressure due to the water would exactly match the pressure created by the pump, and the flow rate would stop.
The pressure at which the flow rate is zero, is called the pump head against a close valve.
This is the highest head that can be achieved by that particular pump.

It refers to the amount of resistance of the pipework on the circuit supplying the index radiator.
The ind...what radiator
sevotech,
The index circuit would be the circuit with the most resistance. You would need to calculate this along with the resistance of the heat exchanger etc to calculate the pump size required.
Ok thanks
So what does 1 head relate to in litres per second

You have been given some information which is likely to confuse you.
The 6m head means the pump can lift the water to a maximum height of 6m but that's with no flow.
As soon as you take flow then the head reduces.
The flow rate depends on the resistance of the circuit you are pumping round.
