ok, no problem
Just triyng to work out why the flow is not good.
Looking at the unvented cylinder, it looks as if it also has a heating element, and only a cold water supply. There is no hot water in? Seems the eletric immesion heater is what heats it upo, or are there ones designed to be fitted to a combi boiler.
The tap is a mixer tap bought from B and Q. It is a Cooke and Lewis ( the one in the kitchen), but to be honest I don't mind the kitchen ones and the bath room as they are ok and although flow is not very good, it is still useable.
The kitchen tap I have is this one:

The main problem I am trying to overcome is the issue with the electric shower.
I will do a descale of the shower head.
Apart from that, any idea what I can look for a diagram to find where the filter for the shower might be to see if it is blocked?
I might also try a pair of these on the kitchen mixer tap to see if they flow the water any better than the flexi pipes:

They seem to have a bigger bore ( 13mm) compared to the 10mm one I have at the moment.
Edit >> I have just seen this on the description of the tap: Fitted with a Neoperl water saving aerator that regulates the flow of the tap and helps you save water with every use
Does this make it flow less? Is the aerator the bit that is screwed to the end?
Edit 2 >> ~Kitchen tap sorted. I removed the aerator from the end of the tap, and the flow is double what it was! both hot and cold. So it seems the flow is ok there and it was the tap design that is doing that.
So now need to work out why the electric shower is so bad.
If you think the combi boiler will be ok to provide shower with hot water, then I probably use that for the upstairs shower when coming to fit it in the next few months and leave the one downstairs as electric as a second bathroom.
If the flow is not very good , can a pump be fitted to the shower? or can you not fit pumps to combi boiler fed systems? I like to have powerfull shower!
Edit 3 >> ( the last edit I promise ) : I just tested the shower with it turned to ice cold. The pressure out of the shower head is really good. Almost like a power shower. but the downside is that it is ice cold. As soon as you turn up the temperature, the flow/pressure drops considerably. Is this normal for electric unpumped showers? Is there a better shower than can be used to replace this to give me a good flow? I do have 10mm cable all the way to the CU unit for when this shower was put in, so the cable will take the supply if a better option is available.
the one I have is this one:

Will something like this be a better option for me as it is a pumped shower?
