Hot water heater query
Hi, some advice needed here please.
I am in the process of fitting a hot water heater to my 1930 Tudor. I have all the bits and pieces, the last of which was the hook up kit that the vendors sell. It's advertised as having a scoop to help the flow of water to the heater. However whereas the heater itself, hoses fittings etc are all nominally half inch ID, the scoop is more like 10mm ID. Now this would seem to be restricting the flow of water and thus reduce the available from the heater. I could easily make a scoop of half inch ID by using the larger tapping of the new pipe, but do the makers know what they are doing? Should I keep the scoop as it is or enlarge it .
All comments/advice gratefully received.
Cheers
