We’re in Ireland so frequent the wife’s uncle’s peat bog during the summer to cut and foot the turf and draw it in so should get a years supply no bother, this can be supplemented by bought wood should we need it.
Solar panels (or photvoltaics) are best used on south facing roofs, otherwise loose their effectiveness.
Our house is on a south facing site and the plan would be to have the solar panels on the garage/workshop roof. I don’t think there is a feed in tariff in Ireland.
Think about underfloor heating as well, but you need consider where your hot water tank and manifold are for efficient heating.
I am thinking about it given the open plan living space in the design. Plan would be to have the tank inside the main house while the boiler would be in a service room in the garage approximately 8 metres from house. I assume the manifold would be near the tank, would I be right?
