    Hello to all, i am currently about to start plumbing my house. the trouble is do i use, oil, gas or geo. was always thinking bout the oil, but it is so expensive to buy and can only get worse i supose. then i heard mixed reports about geo, but wow is it expensive to put in. is there some type of calculation that i can use to work out how much oil would i use. if anyone can help me i would be very greatful. house 4000 sq ft. it will be airtight. 50mm insulated board on the inside of the outside walls, 38mm insulated board on all ceilings. insulation everywhere. i am looking for an approx figure in €€€€€'s as how much oil would cost. anyone else out there that has a building similiar to mine.

    You need to know (at a minimum) the result of 2 calculations before deciding on how best to supply heating to your house.
    1. The annual heat demand
    2. The heat load.
    Without these calculations, imo, you will not be able to make an informed decision. Also, your house needs to be compliant with part L of the building regs. Do you know that your house will comply?

    you need to get a BER assessor to do a ber on your house he will be able to answer all these questions and see that your house comply with part L of building regs should cost around 250 small money in the big scheme of the cost of your house

    A BER has nothing to do with the calculated/guaranteed energy usage for heating. A BER is a guesstimation. Not a calculation.
    Get a civil engineer or an energy advisor or a heating engineer in. Someone with a professional indemnity insurance covering this type of work.

    @ the OP:

    The sourcing of thermal energy depends on the demand and on what is available.

    To decide between the economics of oil or gas (or HP) it is important to know what the return temperature would be.
    The most economic boilers are condensing boilers. However these won't be economical at all if the return temperature from the heating circuit does not allow to run them in a condensing modus.

    Spend a few hundred on proper advise to avoid thousands being wasted.
