I have a central heating system as there is a lot of cold weather in my part of Australia.

In Russia there are central systems in towns (well, most common). But in some villages you may see Russian oven like that: http://en.wikipedia.org/wiki/Russian_Oven

We have an underfloor-heating system. Every Korean house is built with heating pipes embedded in each room's floor. Being covered with a blanket and warmed from below, I easily fall asleep.
