New Radiator getting hot from hot water heating

[Morpheus Cane]

Hi all,
I had a new boiler fitted and while the plumber was here they fitted two new isolation valves in my airing cupboard so I could easily connect a new radiator in the extension I am building.
Well I have fitted the radiator and all seemed fine until I realised that the radiator also gets warm when the hot water is heating up, I have a combi boiler with a unvented hot water tank in the airing cupboard.
I have attached a photo and put arrows to the new valves.
Hope someone can see a issue and if there is a easy fix or if it will cause issues if left. Thanks

I was wondering the same, I think this may be a easier option than trying to find the correct part of the pipe to tee off from.

Bit of a bodge though and check valve will likely stick if your central heating water isn’t the cleanest

There should be 2 motorised valves on the primary flow to the cylinder. One is wired up via a enrgy cutout to prevent the hot water reaching over 85°c

Only if a 3 port is used no need when it's a 2 port

G3 states that there should be at least one 2 port connected via the energy cutout including 3 port valves be it flow share or hot water priority

Yes that's only for 3 port valves no need when it's an s plan system
