It's an addictive hobby. We ordered a hybrid heat pump in March '22 and it was finally installed last week. It's 6 degrees C out here out and this thing is chugging along steadily. It's quiet too. Also adding more insulation as we speak (guys stomping over my WFH office roof now), so as these things happened to get installed in the same months, it's been an expensive month, with about €20k invested, before subsidies. But already thinking about what to do next. Expand the current set of 12 solar panels (has to happen eventually. Our home is about 200 square meter with mostly flat roof, so ideal for adding lots of solar myself), get a heat pump boiler for hot water for showers etc, better windows in some places, etc. Also got a dynamic energy tariff, busy setting up Home Assistant. I have a huge spreadsheet with potential measures, their potentials savings and estimated cost, iPython notebooks with temperature and energy usage graphs, comparison of a dozen heat pumps. Yep, addictive.
