Why would you install with a gas combi? Tell us what you are trying to achieve?

Usually to get higher DHW flow rates, or possibly somewhere to bin off some excess solar PV.

Maybe simpler to do it upstream of the combi rather than after. Then small amounts of temp rise give massive uplift in flow rate.

You can also do it way more cheaply than a mini store. As a mini store is based on heating medium in the cylinder and domestic water in the tubes.

 

So you really need to connect the combi to system boiler for the proposed to work.
