• PassivHaus appeals solely for the challenge and standard of build required, it doesn't make sense financially really (in the short term at least). It has helped with achieving planning for a marginally larger build, but the plot already had permission for 2x 2 beds.

    I'm currently looking into the ST panels/thermal store a bit more... it looks as if PV panels and a SunampPV "battery" will be a better solution than ST. We want to keep to as few panels as possible (the neighbour behind and Dad dislike the appearance of large arrays).

  • Fair enough. I think a proper integrated PV roof looks infinitely better than a stick-on array, but each to their own. Well done for going PH. What will your heating be (backup that is, I know with PH it is minimised). Solar water makes sense if you've got no easy alternative for hot water (I.e. if you were off gas grid).
