I asked the same question.

Before I came, I was told that winter herr will be fairly cold and we will need to get at least fan heater for the bedroom. Now it's almost Christmas (in fact today is the winter solstice in norther hemisphere) and for me this is actualy very nice hence no need for the heater yet.

So, is this normal for this time of the year ? will it get much colder ? Does it augur a long and hot summer ahead ?

Cheers
