Using wind power/ Energy to heat a stratified buffer tank for central heating

    I am currently monitoring my wind speeds to assess the viability of a wind turbine as a possible heating source or to offset my ESB bill (will depend on smart metering which is due in 2009)

    Has anyone any figures or info on much Energy is required to heat a stratified tank i.e a buffer tank so it can be circulated for central heating. I am considering a 1000 / 2000 litre heavily insulated tank with two heating elements.

    Companies that sell wind turbines have touted the fact that the proven 2.5 kw can be used to heat a buffer tank but no real info is provided on the tanks used etc

    I am interested in figuring out how many kw are needed to keep a tank at a specific temperature e.g 60 C. The buffer tank will be circulated around the central heating system. I have insulated my house to a high spec so the next area to look at is the heating source.

    I would use the option of using my oil burner to top up the tank where necessary. Burner etc is in a shed so I have room to implement this project.
    Solar is being considered also to top up the tank but it may not suit the heating profile usage

    Any info or advice would be appreciated.
