Birch, plane, alder, spruce, pine. That's about 3 year's worth. Our house has a big stove in the middle and when it's minus 25 Centigrade a 'nest' of wood (maybe 30 pieces of wood) is burnt and when the ashes are not glowing anymore a steel plate is slid across the chimney keeping the heat in which circulates in the 'double skinned' stove. The bricks retain the heat and give it out gradually. There are electric radiators attached to the walls all round the house but these almost never come on as the stove does the lot. We just have T-shirts on here in mid-Winter. British houses are freezing inside!!
We just had 2 nights in a B&B in England and wish we had brought our own hot water bottles with us!
When I was a teenager my dad's second wife used to say "Put another sweater on." - Well, that's stupid: I say "Turn the heating up!". How can you concentrate on doing your homework when your nose is cold?
Houses in Britain are built poorly. In Scandinavia buildings are constructed with proper insulation and 3 panes of glass in windows.
Vehicles get plugged into the 240v electricity - engine water gets heated and there's an inside fan to warm up the air inside.
The sauna has obviously developed from Siberia where it's blooming cold (as a third of Finns came from Siberia, according to genetic analysis). It's simply a warm room where you can get out of the cold and a clean place where women can have babies. The only country in the world to have a different word for sauna are the Swedes - they just have to be awkward - they call it 'bastu'. That's one reason why Finns think Swedes are absurd.
Sauna is NOT a luxury - it's just a room with raised benches and a stove (electric or wood heated) at which you chuck spoonfuls of water. A little vodka and beer, and sauna is a nice place to have a chat and a think. Why the Brits are so against saunas and heating their cars with electricity which is so easily available, and environmentally better, is beyond me.
We should really take the best of both countries. Finland should really have nice pubs as in Britain - but is lacking in this department.
Finland has a nationwide good mobile phone and internet data network - Britain is complete crap in this. Why?
Neither country is better than the other in my experience, but I do think it's wasted opportunities not to grasp the good ideas and incorporate them into your own culture.
