    My flat suffers from poor mains pressure and we have a direct heat setup with combi boiler.
    The boiler is rated up to 3Bar, so I was thinking of installing a cold water tank to feed a twin pump supply cold and into the boiler for hot (both 15mm).

    My questions are
    - Is this a feasible setup
    - Can I use a single 28mm feed from the tank to a double 15mm manifold into the pump or should I install two 22mm/15mm feed pipes from the tank instead.

    Thank you in advance for any help you can offer.
