see guy who came to install solar on roof see we have the typical Portuguese solar water heater, so he then told us we are crazy because we have our regular electric boiler on, saying "you only need to use your electric boiler in the winter, in the summer you should only use the solar water heater" and then he switched off our boiler, then this morning we had had luke warm to cold water in shower, it's so interesting their standards of living are so much lower and every single thing here is about saving money and not life quality, opposite to Kardashev Scale #onlyinportugal
