Hi my name is ***** ***** lets see if we can get you sorted in the shortest possible time.
The name of the boiler is the sticker left behind when the system was filled as that is the inhibitor in the water.
Any other names on the boiler?
Customer: replied 1 year ago.
It says protherm.
Expert:  Andrew Smith replied 1 year ago.
Any other details as they have made a few?
Customer: replied 1 year ago.
Sorry mate that's it! Not ideal I know.

See if there are any similarities
Customer: replied 1 year ago.
Yes that looks like the one mate.
Expert:  Andrew Smith replied 1 year ago.
Ok, can you turn the heating off, turn the boiler off and then tell me if the boiler clicks when you run the tap?
Customer: replied 1 year ago.
No mate no clicks
Expert:  Andrew Smith replied 1 year ago.
That is why you have no hot water then.
Your divertor valve is not working and probably needs rewashering at the least
Customer: replied 1 year ago.
However, when its on central heating mode (ie winter mode) it seems to heat fine. And the hot water for shower works great no matter what mode. Its just summer mode and kitchen tap that is cold. Headwrecker!
Expert:  Andrew Smith replied 1 year ago.
Is it an electric shower?
It works fine in ch mode as the boiler is already running, when on hot water mode it is the divertor valve that fires the boiler.
Customer: replied 1 year ago.
So when it comes to fixing, I should tell a local plumber what? Thanks mate
Expert:  Andrew Smith replied 1 year ago.
That your divertor valve is not working and needs rewashering.
Ring a couple of local people and get the best price
