Hi,

Just a quick question....... When looking at different circulation pumps what does the sizes mean regarding 4m, 6m & 8m head???

Thanks.

It's relates to the total height you need to pump the fluid, taking in to account any friction.

In laymans terms head is a measurement of the oomph that a pump has.

The head is the total pressure drop round the circuit, due to friction etc. It has no connection with how high the pump has to push the water.

It has nothing to do with height; just friction.

Dear doityourself, are you trade? Gsr? Or just an annoying know all?

Thats what i need laymans terms!!!

My pump is situated in the airing cupboard upstairs next to the hot water tank at about waist height. Would this make any difference to what pump i need say in terms of the pump not being on ground level????

It does relate to the height it needs to go actually and it takes in to account frictio. The meters head is a calculation of psi which also determines how far it will push it

The head is the total pressure drop round the circuit, due to friction etc. It has no connection with how high the pump has to push the water.

Geodetic head is the difference between the switch off point of the pump and the outflow height where the Manometric head is the sum of the total friction loss and geodetic head.
