We’ve had problems with recurring damp in our room on the ceiling at the join to the front wall. HA have been out several times and tried replacing insulation in the loft and even put vented roof tiles on. It hasn’t worked. As a result the room always feels cold whether the heating is on or not. I dug out the gro egg and it’s saying the room is 14.2 degrees. I’ve been looking at oil filled radiators and halogen heaters, what’s the most cost effective way to heat it up a bit?
