    Hi all, just wondering if anyone can recommend someone to do a phpp heat demand calculation? Not too worried about being certified but need an indication of heat demand to decide on a heating system.

    Thanks

    why phpp if its only an indication

    “I can’t pay my staff or mortgage with instagram likes”.

    How else would you get an idea of your heating demand without doing it?

    at a simple level:

    for each room: surface area by U value by delta T

    then add in for ventilation heat loss.

    see attached from SEAI

    The phpp calc is a lot more onerous and will cost you more for an indication figure

    “I can’t pay my staff or mortgage with instagram likes”.
