Could you please advise ?
For my new kitchen I chose the above sink which has a tap hole on the
side.

I saw a nice really modern tap with spout reach of 190 but it requires
minimum 0.5 bar pressure to run the tap.  Seems that most of the
contemporary taps require 0.5 bar pressure or higher.

Could this mean that unless a pump is installed the hot water just
trickles ?
How would I know what bar pressure we have in the house. It is a
detached house with the water tank in the loft and the hot water
cylinder on the first floor in the bathroom.      My old fashioned tap
with hot and cold water opener on either side worked very well.

Should I go for a traditional tap with cold water opener on the right
and hot water opener on the left ?     I would want the spout to reach
the middle of the sink.   Has anyone got the same sink and can
recommend a suitable tap ?

thanks

The head of water at your hot tap is determined by the vertical distance
from the tap to the top surface of the water in your loft header tank. (The
position of the hot tank doesn't matter).

0.5 bar requires a head of just under 17 feet - whereas the actual head at
the kitchen sink in a modern 2-storey house is nearer 14 feet - unless the
header tank is mounted on a platform or brackets some distance above the
loft floor.

Chances are the the spec is somewhat conservative - and that it will
actually work, and give an adequate - if not brilliant - flow.

Thank you for the information -

Occasionally, taps can be converted by removing a flow restrictor on
the
inlet pipework. If there is one on the hot inlet, take it out! They
often
take the form of a plastic screw inserted into the pipe that seriously
reduces the available bore.

Is this relevant and true and would this make a difference ?

Such restrictors are often used on mains feeds to toilet cisterns. Don't
know about kitchen taps - never seen one on a hot tap. I would have thought
it was more likely to have one on the cold tap if this is mains - and the
hot gravity fed - to get get a better balance when blending hot and cold.

It may well be though on modern mixers, which may be designed to work on 
mains pressure CW and DHW, rather than stored.

There may be different models of the same type of tap available. When we 
fitted mixers in our bathroom you could get different ones depending on 
the water supply arrangements.

Note to the OP, make sure that the design of mixer is  suitable for 
mains CW/stored HW- these have separate hot and cold feeds down the 
spout. Ones for mains pressure Hot and cold can have one single spout 
where the water can really mix in the spout. Use one of these on  the 
other sort of system and the pressure of the cold water can cause 
problem with the hot flow.
