If like to add to the space heater. I've got solar panels, the guy installing them also has infrared panels. We got to try one out, and never looked back.
A infrared panel will warm a small space very effectively. Way better then water radiator heating (which is the norm here). It's also instantaneous and is a radiant heat (like a wood burner).
We've ditched all our gas heater radiators and went with infrared. It's cheaper and easily regulated per room.
electric water kettle (fuck gas stoves and also faster),
Are they not common where you live? I'm in my 30s and have had electric kettles my whole life. I don't have one at the moment though - my espresso machine has instant hot water and that's been sufficient, and much faster.
Also - if you're in the USA and think kettles are fast, you should see kettles in countries with 240v power. People from Australia complain about how slow kettles are in the USA.
