disconnect/isolating primatic cylinder

[jonCar]

Hi, i have a primatic cylinder system which i will be replacing soon, in the mean time is it possible to disconnect the f & r from/to the boiler and leave the cold water supply to the cylinder from the header so it can be used to supply DHW only by using the electrical immersion?
This will be a temporary measure for a week or 2.
Many thanks in advance.

Yes.

Isolate the boiler safely as the cylinder primaries you will be capping are also feed and expansion!

Thanks for reply, so I drain the CH system, cap the cylinder primaries and ready to use with immersion?

Yes.
