Thank you very much. One hot unit is fine as we are just two people. So based on what you said the choice is between 10.5Kw and combi. In general I assume combi will give a better pressure, please correct me if I am wrong.
And how can I measure the pressure and flow?
Hi
I recently moved to my new house. I am a fan of powerful shower and unfortunately I found a 8.5Kw electric shower which is not good at all.
Now I have some options and any help would be appreciated:
-replace it with a 10.5Kw if the wiring allows. It costs about £400 including the labor...
