npub1zg9vcdj64tpznh3kpatank6pdhlh2wz4eq74zq23fru2nsmh7vfqjunh26 (npub1zg9…nh26) a heat pump for the hot water makes a big difference, too – both in demand and consumption (ours draws about 300 W electricity for about 1 kW of water heating). The downside is that the fan is not quiet enough so, in order not to hear it at night, I've got it on a timer to run only during the day – which also means that it's running when the performance coefficient is a tiny bit higher.
