Hi! I've recently bought a Beko 7kg condenser dryer and noticed that it gets very warm to touch when on. It's located in a reasonably sized bedroom and air can circulate all round and under it. None of the air vents are obstructed. I put in on for 50 mins on high and when I checked it after 30 mins, the room temperature had gone up 2.5 degrees and the top of the machine was the temperature of a hot radiator. Is this normal?
