    Boiler woes

    I first posted this on the UKHA forums but it was suggested to post here for additional views.

    Our current boiler is starting to play up, I keep having to reset it
    as it fails to run when required. I know it is a particuliarly bad
    model as it has been on Watchdog, Potterton Suprima. In addition it
    is non-condensing and the Energy Saving Trust state efficiency of
    ~75%.

    So I am likely to replace it in the next few years, but this posses
    some questions:

    - Should I go the whole hog and change to an unvented system (what
    are the benefits?)

    - In the future I plan to install solar panels for hot-water and
    also a wood pellet stove for the front room with a small back-
    boiler. Therefore, the gas boiler will then become secodary heating
    source just providing top-up to the renewable heating supplies. But
    I need a system that can cope with this more complex setup.

    - Any recommendations on manufacturer? I am thinking Viessmann as
    they seem to have a good approach, German engineering and have good
    controls and integrated with their own solar system. But I have also
    been recommended Worcester Bosch and Baxi.

    Any thoughts, comments would be appreciated.
