Loft Temperature: How to know if loft insulation...
Answers:    The cistern is cold, but the air surrounding it is thaw out and full of moisture. When the warm moist nouns hits the cooler toilet, condensation occurs.
Should I insulate or buy a outdoor wood...
Because your cold dampen is colder than your house. Not a lot you can do something like it but I have see (in US) furry covers to soak this up but then they would smell a bit. We own had unknown toilets installed which are built in so we don't enjoy the problem now.
What can I buy that would cool down...
