* Every household has an electric kettle
* Kettles boil very quickly (due to power differences)
* Most households have radiator-style heating, which takes much, much longer to heat up a room than US-style forced-air heating
The US secretly has 240V power almost everywhere, but we use center-tapped transformers upstream of the service connection that provide two 120V legs (180 degrees out of phase). So lighting and appliances all get 120V (typically 15A), with the exception of high-power items like cooktops, ovens, and these machines we have for drying our laundry indoors.
I'd suggest that over redoing your outlet, though you will have to periodically descale your water boiler, because of sheer utility and portability (you can move and you'll still be able to just plug it into a standard 1-phase 120V outlet.)
Recently we had a bought of dry cold weather. In -10 C and dry I was wearing less insulation and feeling warmer than +5 C with high humidity. Real eye opener to understanding the impact of humidity and how I can adapt to my winter climate better.
