Mind you, if its anything like our flat even if you left the heating on permanently with the thermostat turned full up it wouldn't get that warm. Although the impact on our gas bill would no doubt be spectacular.
That said, never lived in a house in Scotland that didn't have central heating, gas being the fairly obvious choice. I doubt thermostats are uncommon at all.
My parents house in Moray didn't have central heating - the halls of residence I lived in when I first went to University had central heating and felt tropical to me. No sooner had I got used to that then I went home again for the Xmas break and felt like I'd moved to Siberia...
When you think about it this product is so badly thought out on every level!
