All this proves is that you have low mains pressure

Compltely and utterly wrong

main pressure is about 8 bar

what i have is a combi that cant heat water fast enough and has
minuscule hott water store


Bite the bullet and do the proper job, Mains pressure hot water tank
fed from whatever boiler you have and if in a hard water area all fed
via a pukka ion exchange softener.

Then never have a hot water shortage ever again

Yes, cos storing hot water in a tank until you use it is better than having
it on demand.

Correct.

My combi is ten years old, never been serviced and supplies continuous hot
(hard) water every time the tap is turned on, likewise the mixer shower,
which is powerful enough to actually hurt if it's on full.

no, it doesn't unless yu have around 50Kw rating


No water softener ever been in this house
To the OP, get a combi if you have reasonable mains pressure, if it comes
out of the tap like someone having a ****, go the other option


oh the water comes out aright. Cold

work out how big a combi needs to be to say dump 400 litres a minute of
water at 60 degrees

then work out how much more expensive that is than a small boiler with a
mains pressure hot water tank

then do the sensible thng
