water pressure question - will high pressure mixer work with low water pressure?

That may seem like an odd question but basically we've picked the mixer we want for our new bathroom but its got a minimum of 1bar operating pressure. We currently have a conventional system and wont have that kind of pressure although its not bad. We will be upgrading the heating system sometime in the future once the extension is being done as we dont want to have to get the boiler installed now and then moved.
So I'm wondering what exactly will happen with the mixer? Will it simply not function at all or just provide a poor flow of water? Could live with the latter but not the former.
The backup plan is to source a cheap low pressure mixer with the same spacing for the pipes (seems to be fairly standard 150mm as far as i can tell) and use this until we get the system upgraded.
Any thoughts or advice?

As the cold (mains) water flow is probably at a higher pressure than the hot water, you may get a very poor hot water flow, or if it has a thermostat, it may cut out altogether.
if you have problems you could install a booster pump to increase the flow rate before it hits the taphead.It's nice to be nice .....:beer:
You HAVE checked google before asking, haven't you?;)

As I got home last night the obvious solution dawned on me, keep the existing shower mixer and use that until we get the boiler changed. I've measured it and the pipe spacing is the same so it should be possible I think. :j0
