Advice about twin coils

[jimgiraffe]

Hi

Just got a twin coil cylinder, for an unvented system, do i need to connect in the solar coil before using the cylinder or can I do it at a later date???

Cheers

Can connect it whenever you want. Customer had new boiler and unvented cylinder with twin coils as wanted solar thermal. Couldn't affor it all at once so the boiler was changed and twin coil cylinder installed. Solar to be added at a later date.

I thought that was the answer but began to doubt myself.
