Yep, and cooling is rapidly becoming a problem comparable to heating; summers are getting hotter but Finnish construction norms are still all about keeping homes warm in the winter as opposed to cool in the summer. Few Finnish homes have AC, except for those that have two-way heat pumps. Portable AC units have been in very high demand in the past few summers due to heat waves that used to be exceptional but are quickly becoming the norm.
