Fitting a combi boiler to exsiting system boiler pipework

Hi,

New to the Forum can anyone give me any advice to this,

Looking at replacing my system boiler ( tank fed cylinder etc..) with a combi. Just need some help with how to connect to exsiting pipework)

Is this correct,

Cap of exsiting hot water just past the tee when it comes of the cylinder. Then connect new hot water outlet from boiler to exsiting hot water pipework (15mm)?

The boiler is going to be in a new position so do i just tee into nearest hot water pipework?

Cold will just go into boiler (15mm)

Do I connect new flow and return to exsisting flow and return?

What about the flow and return that was used to heat water in old cylinder?

Any help would be appreciated.

Thanks

I'm sure all these questions will be put to rest when you installer fits the boiler for you

Just make sure he doesn't leave any dead legs and notifies the boiler installation as per regulations

Little chance of getting advice on this forum about how to install your own boiler from a professional installer.
