On waking this morning with heating turned off since 10pm last night; Living room 8.9C, bedroom 8.6C, hallway 8.9C, bedroom 3 (unheated) 6.5C, kitchen 8.3C Now you know why I hate these freezing temps. My exposed, detached, rural bungalow is insulated with max loft 270mm and cavity walls have been done. I must be losing it all via the suspended wooden floors which are vented via two air bricks in each room. In comparison, my previous house (1930s semi with crappy storage heaters), rarely dropped below 10C even in un-heated rooms.
