No double glazing or central heating Chez Col!
Basement utility room - unheated.
What would be the main living room in most people's houses is a bike shed, gym, store room in mine and though it has a gas fire, I never use it - unheated.
Kitchen - unheated, except by cooking.
Lower stairs, landing, upper stairs - unheated except by heat that escapes from elsewhere.
First floor room which most people would have as a bedroom, but is my living room - unheated unless temperature drops below about 10 degrees C, then it is whatever temperature the little gas wall heater gets it to. It is actually quite efficient so I would prefer not to turn it on above 10 degrees unless visiting softies make me.
My attic bedroom/office has a gas fire which is incapable of going low enough for me so I don't tend to light it until the temperature drops below 10 degrees. I get fuzzy-headed once the temperature gets above 20 degrees so unless it is very cold outside, I'd probably turn the fire off every now and then to let the room cool down a bit.
Bathroom - unheated. Usually only receives heat from elsewhere in house plus heat escaping from the water heater. Unfortunately ... the cold winter completely killed the bugger! It froze up and cracked a pipe and I can't afford to get it fixed. The front of the heater is off to allow the escaping water to drip down into the cistern below. This means that there is effectively a hole in the bathroom wall allowing an icy blast in. So bathroom temperature = close to external ambient at times. Washing in cold water in a room at freezing point is character-forming! I could boil a kettle, but I only bother when I'm washing my hair.
The lack of hot water over the past couple of months has had me doing the washing up in my unheated kitchen with cold water. You get used to it, and the feeling comes back in my fingers after an hour or so ...
