T off from a combi boiler

[f49h]

Hi Guys
I am fitting a mixer shower. It would be a lot easier if i fit the pipes in a cupboard next to my combi boiler. I was going to T off the hot water pipe from the boiler to the shower and T off the inlet to the boiler to the shower.
If i T off from the boiler inlet (cold) will it have any effect on the boiler. e.g. will it strave the boiler of water
Cheers

Since a combi will only really feed one outlet at a time then it will make little difference.

Unless your incoming mains pressure is particularly low then that will be ok.

Cheers Guys

the pressure is around 3 bar
