That reminds me of a house built here in SE Canada in New Brunswick. It's a super efficient home with quadruple glazed windows and walls 1m thick or something like that. The entire house is heated with a unit using the power equivalent to a hair dryer. Just for some perspective it can easily get to -20C or -30C in winter in New Brunswick. It's airtight and very well insulated but yes built that way from the start.
