    Just a quick update

    My January Pinergy bill landed, and it's €140 Net after €30 FIT.

    So €140 to run the house, cooking and heating, and run an EV. That's less than €5 per day 🤩

    Heatpumpmonitor.org has my SCOP at 3.9 👍

    Hi champion, I have been lurking in the background for some time now. Your figures are very impressive, considering that your walls are cavity/hollow blocks do think that the external insulation that you plan is worth the expense ?

    The only way it can be worth it is by doing a self install of the wrapping.

    I am possibly spending less than €500 a year on electricity for heating, so I wouldn't have a hope in hell of recouping the €20k+ that it would cost to have it done by a company, over my lifetime.

    Yes, the house is far more comfortable now, and will be even more so, which is just about making it worth doing myself.

    Of course, the low running cost is down to my batteries and 5c Pinergy night rate power
