    i am starting a new build and need to make a decision on heating SOON. i am trying to decide between geothermal with ufh or a solid fuel range heating radiators with oil for back-up. maybe solar panels with either of them. everyone i have spoken to has a different opinion and i could really do with some advice with someone who knows what there talking about e.g someone who has had geothermal ufh for a few years. please help!!!

    Your architect/civil engineer will tell you about the energy demand. This is the point to start.

    Without knowing all the details a basic thing most people can agree on is this

    Geothermal is excellent if
    1. Its installed correctly and sized correctly.
    2. Its installed into a house which is reaching for excellent insulation and airtightness standards this is prob most important in any new build.
    3. You get a good quality geothermal unit.
    4. You understand the way underfloor works that it doesnt give a blast of heat like with rads . The whole purpose is to create a Constant , comfortable ambiant temperature. When people are used to rads it can be hard to adjust to underfloor, personally i love it , others dont. So to maintain this ambient temp , people must understand opening windows or doors or any draughts from outside etc can dump out that heat pretty quick and it will take a while to build up again.


    If your not looking to excel in the insulation and airtightness standards personally i would go with oil/ solid fuel stove and link them both to a buffer tank .

    I agree with heinbloed , you need to find out the enery demand and see what suits then.

    What does the term " excellent" stand for , Outkast_Ire?

    What is the anticipitated price per kwh thermal energy? And what price does the HP installer/seller guarantee?

    There are worlds between the sales men bubble and logic.

    excellent at the moment with current technologies and products to me would be a home that reaches that tries to reach the passivhaus standard or gets very near to it. that to the best of the knowledge strives for less than 20kwh/per m2 per annum. That would be my start point and find a heatpump thats suits from that.

    Im not overly familiar with heatpump brands as the im not installing them and its been a few years since a new build house has even asked about them . Is the Op wants to go for heatpump id reccomend her to do a good amount of research on them first.
