Yes well...
The problem here is that my house is on me ill and is completely uninsulated...
So, the moment you remove the heat it is freaking freezing...
I calculated the there is 50,000Kg of concrete in my bedroom roof... if you know the specific heat capacity of concrete you can work out that you need a nuclear explosion to actually heat it up...
