    Here is what im planning on doing.

    Installing a 6 KW turbine while building my house

    With this "Free" electricity im going to be running my house on it as much as possible.

    What i what to do is have an immersion heater to heat my rad, & hot water. with a back up heater of maybe a Back Boiler or Pellet burner.

    My house will be at an B1-A3 rating with a HVAC systems It is 220m2

    Can someone tell me is this Plan is wise Or even possible. With the way Oil is going at the moment and for ever more. It would be a BIG mistake on installing one in a new house.

    A couple of thoughts:

    6kW will be the maximum output of the turbine under ideal conditions, and will not be available most of the time. It is unlikely that you will be able to supply all the energy needs of the house from this supply, so a normal ESB supply will also be needed. However a grid-tied wind turbine system will feed excess power back into the national grid when available and you will be paid for it.

    Electric heating is always expensive, I would look into a geothermal system combined with underfloor heating. This can be very efficient and the output of the wind turbine can offset some of the cost of the electricity used by the heat pump.

    There are systems using stored water at high temperature to provide heating, and the output of a wind turbine can be used to heat this store directly. They can be used in conjunction with evacuated tube solar panels which also provide heat input to the thermal store. This can be an efficient system, however the thermal store needs to be very large, and highly insulated in order to make it practical. The initial costs would be very high.

    You really need expert advice to design the overall system, try and find a consultant who is not trying to sell you anything in order to get impartial advice.

    Yes this will be a grid tied turbine

    I am of course going to get a Pro in to set it all up and what not. Just putting the Question out there to see if anyone else has gone down the same lines.

    As for Geo thermal and underground. Im not a big fan of them at all Hence the Rads!

    But doesn’t all good ventures have a initial high cost!!!!
    An when you are borrowing 180k what another 15-20 on top of that.
